DL16S • DL32S Owner’s Manual

Chapter  : Welcome

Hello everyone! This is the DL6S • DL32S Owner’s Manual...we hope you like it!

Instead of one massive document containing detailed information about the hardware and sofware, we have divided them into separate manuals. Simply decide if you need assistance with the hardware or sofware and dive on in. The water here is warm and crystal clear.

The following pages describe the hardware side of things and should remain relatively unchanged throughout the life of your product. The sofware, though, is another story. The Master Fader app is always being updated...even right now this very minute! This means frequent updates to the Reference Guide, ﬁrmware and more. With each major release comes an updated Reference Guide.

So there you have it. Again, we hope you like it. If you have any questions or comments about this Owner’s Manual, please contact us at: www.mackie.com/support

About This Guide

This guide is designed to be accessible, with subsections as complete as practical to minimize having to electronically leaf back and forth looking for the whole story. This guide provides the following resources:

• A general overview of the DL6S • DL32S’s facilities and features.

• Dissection-by-dissection description of each input and output.

• Hookup diagrams depicting some of the more common setups.

As the saying goes, “a picture tells a 000 words”. With that thought in mind, we added quite a few illustrations, screen shots and other images throughout to accompany the text.

This icon marks information that is critically important or unique! For your own good, read and remember them...it is a good idea to pay special attention to these areas in the Owner’s Manual marked with the “VERY IMPORTANT” hand icon.

There’s an illustration of a microscope, so, of course, you’re going to get more detailed information when you see this little guy. There are explanations of features and practical tips listed here.

It’s a good idea to pay attention to text displayed next to a note icon, as this icon draws attention to certain features and functions relating to the usage of the mixer.

Chapter 2 : DL6S and DL32S Side and Rear Panels

Introduction

The side panel of each DL6S and DL32S is ouﬁtted with a power connector and power switch, while the Kensington Lock resides on the rear panel.

Power Connector

This is a standard 3-prong IEC power connector. Connect the detachable power cord (included in the packaging) to the power receptacle, and plug the other end of the power cord into an AC outlet.

Make sure that the AC power is matched to the AC power indicated on the side panel (below the IEC receptacle).

Warning: Disconnecting the plug’s ground pin is dangerous. Don’t do it!

In fact, it’s a bad idea to remove anything from – or add anything to, for that matter – the line cord. Again, don’t do it!

DL16S • DL32S Owner’s Manual

Power Switch

Press the lef side of this rocker switch in to turn the DL6S or DL32S on and press the right side of this switch to turn the mixer o.

Kensington Lock

An optional Kensington Lock provides an extra level of security should the mixer be lef alone, unwatched. There are a wide variety of cable apparatuses to choose from to secure your mixer via the Kensington Lock security slot. Feel free to decide on what type works best for you by perusing the Kensington website: http://www.kensington.com/

As a general guide, the DL6S • DL32S should be turned on ﬁrst, before any external power ampliﬁers or powered speakers. As such, it should also be turned o last. This will reduce the possibility of any turn-on or turn-o noises in the PA.

While the Kensington cable and lock provide some level of security, it is NOT foolproof or guaranteed protection. LOUD Audio, LLC. is not responsible for the loss, thef, damage or destruction of your mixer whether a Kensington Lock has been used or not.

Chapter 3 : DL6S and DL32S Front Panel

Introduction

Each DL6S and DL32S mixer is ouﬁtted with one /4" phones output jack (and corresponding phones knob), a USB interface slot to stream multichannel audio to and from, an external Ethernet connector slot, a built-in Wi-Fi antenna and power and Wi-Fi LEDs.

The DL6S has 8 XLR input jacks, 8 combo input jacks and 8 XLR output jacks, while the DL32S has 6 XLR input jacks, 6 combo input jacks and 0 XLR output jacks. Let’s take a look at each of these features, starting with the inputs.

XLR and /4" Inputs

All channels may accept a balanced mic or line-level signal using an XLR connector. They are wired as follows, according to standards speciﬁed by the AES (Audio Engineering Society).

In addition to accepting balanced mic or line-level signals using an XLR connector, channels 9-6 [DL6S] • channels 7-32 [DL32S] may also accept /4" line-level signals driven by balanced or unbalanced sources.

To connect balanced lines to these inputs, use a /4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for Tip-Ring-Sleeve, the three connection points available on a stereo /4" or balanced phone jack or plug. TRS jacks and plugs are used for balanced signals and stereo headphones and are wired as follows:

To connect unbalanced lines to these inputs, use a /4" mono (TS) phone plug, wired as follows:

SLEEVE

DL16S • DL32S Owner’s Manual

XLR Outputs

These male XLR connectors provide balanced line-level signals that represent the end of the mixer, where the signals enter the real world. Connect these to line-level inputs of your main PA system, stage monitors, external eects devices, headphone ampliﬁers, and/or whatever else you desire. The PA/monitor speaker system could either be passive (powered by external ampliﬁers) and/or powered (with built-in power ampliﬁers). You may run separate mixes since all outputs are independent of each other and are completely routable via the Master Fader control sofware. Pretty cool, huh?!

They are wired as follows, according to standards speciﬁed by the AES (Audio Engineering Society):

This knob is used to adjust the volume from the phones output jack, from o to maximum gain (max). The phones knob is an analog control, and is therefore NOT recallable.

Warning: The headphone amp is loud and could cause permanent hearing damage. Even intermediate levels may be painfully loud with some headphones. BE CAREFUL! Always turn the phones knob all the way down before connecting headphones, soloing a channel or doing anything new that may aect the headphone volume.

Then turn it up slowly as you listen carefully.

For the most part, this LED will illuminate solid green when the mixer is powered on and funtioning normally. However, this LED has several other identiﬁers, as well. Please refer to the table in Appendix D for all possibilities.

Wi-Fi LED

For the most part, this LED will illuminate solid green when Wi-Fi is functioning normally and a tablet or computer connection is established. However, this LED has several other identiﬁers, as well. Please refer to the table in Appendix D for all possibilities.

Force Update / Network Reset Button

The force update / network reset button is conveniently located in between the power and Wi-Fi LEDs. In a perfect world, this button would just sit there without a care in the world, umbrella drink in hand, beach, surf and sun on a daily basis. In all likelihood, this button will live his / her dream out, while the rest of us can only dream of such a life.

The DL6S, DL32S and Master Fader app do a great job at letting you know when either (or both) the sofware and ﬁrmware need updating, but this button here forces a complete ﬁrmware update if the need ever arrives.

Force Update: Here’s how to force a ﬁrmware update: ﬁrst, turn the mixer o. Now, with a bent paperclip, poke the force update button, then power up the mixer with the button depressed. The mixer will boot and you will be prompted with an update bubble the next time a tablet or computer with the Master Fader app is turned on.

Network Reset: Press the button for 5 seconds and release to reset the network settings to its default. This is useful if you’re not sure of the current conﬁguration, if the mixer isn't being discovered by Master Fader or can’t connect. It resets the mixer to access point mode using the default network and password. Additional information regarding default conﬁguration is discussed in greater detail on the next page.

Network Reset+: Press and hold the button for 30 seconds, then release. Like Network Reset above, Network Reset+ resets the mixer to access point mode using the default network and password, but it also completely reloads the ﬁrmware in the Wi-Fi module (leaving all other ﬁrmware intact). Use this if Network Reset doesn’t solve the network related problem or if instructed by support.

Now that you know how to force an update and reset the network, here’s a friendly reminder that you should let the button remain peaceful, calm and tranquil, only forcing a ﬁrmware update if instructed by Tech Support. Thank you for listening!

Save any current show to your tablet or computer before forcing an update or you may lose it. The show and your sanity!

USB Interface

The USB type B connector allows multiple channels – 6x6 [DL6S] • 32x32 [DL32S] – of recording and playback to a connected computer over USB 2.0 by presenting the DL mixer as an audio class 2.0 compliant device. What this means is that connecting it to a Mac should work automatically with no additional drivers. Windows drivers will require separate installation, but this is included. Simply download it from our website!

Any combination of channels or outputs may be selected as the record source and playback destination.

More information about recording and playback may be found on page 0.

Page 9

Wi-Fi Antenna

DL16S • DL32S Owner’s Manual

The DL6S and DL32S both feature built-in Wi-Fi for wireless control via Master Fader from iOS, Android or Mac/PC.

By default, your mixer will use the built-in Wi-FI (Access Point mode). There are no changes necessary; it is ok to leave all settings as-is. Gently remove the antenna from its “clasp” and rotate it 90° CLOCKWISE so it points straight up. On your device running Master Fader, go into the Wi-Fi settings and look for the default SSID (Mackie DL6S or Mackie DL32S). Connect and enter the default password (MixWithMackie). You should be good to go!

Wi-Fi SETTINGS:

Default Wi-Fi Name - Mackie DL32S or

Mackie DL16S

Default Wi-Fi Password - MixWithMackie For security, we recommend changing your

Wi-Fi password in the Master Fader app.

NEED TO RESTORE DEFAULT Wi-Fi SETTINGS?

Power up the unit and wait 30 seconds. Press and hold the recessed reset button for 5 seconds.

(Found between the front panel Power and Wi-Fi LEDs) The Wi-Fi name/password will revert to the defaults listed to the left.

If not using the built-in Wi-Fi, there are two other options that may be conﬁgured with Master Fader.

In External Router mode, you can connect your mixer to an external router using a cable plugged into the mixer’s Ethernet port. See below for more detail.

Another option is using Wi-Fi Client mode to connect wirelessly to an existing Wi-Fi access point. In this mode, a router is not physically connected to your mixer. Instead, the venue runs a dedicated (and protected) Wi-Fi access point for their internal use. If using this mode, there are a few steps necessary to get dialed in. These are settings in the Master Fader control app and more detail can be found in the Master Fader Reference Guide.

Utilizing the built-in Wi-Fi will satisfy most users. Only those with very speciﬁc Wi-Fi requirements (extra-wide range demands, integration with existing network, etc.) would need to use the External Router or Wi-Fi Client modes.

Ext. Control Connector

Only one networking mode may be selected: () Access Point, (2) External Router OR (3) Wi-Fi Client. Complete directions for choosing and conﬁguring these modes may be found in the Master Fader Reference Guide.

The purpose in life of this 00 Mb network connector is to connect the mixer to an external Wi-Fi router via CAT5 Ethernet cable, thus enabling wireless control.

Plug one end of the CAT5 Ethernet cable into the mixer’s network connector [Ext. Control] and the other end of the CAT5 Ethernet cable into a LAN port on the router, NOT a WAN port. Most routers allow the use of either a straight-wired cable or crossover cable, but if you have a choice, a straight-wired CAT5 Ethernet cable is the way to go to ensure smooth operation with any router.

Do NOT connect an external router when using Access Point mode. This can create an unstable network causing some devices to stop operating properly. When conﬁguring for External Router, change the settings with Master Fader, then connect the external router.

Chapter 4 : Recording and Playback

Introduction

As mentioned a couple of pages ago, recording and playback is possible when a computer is connected to the DL6S or DL32S via the USB type B connector. No additional drivers are required to work with macOS. Windows will require the installation of the Mackie USB driver.

Any combination of channels or outputs may be selected as the record source and playback destination.

Getting Started

Recording and/or playback with a DL6S or DL32S is possible from a DAW application or from other applications such as iTunes, Windows Media Play, Spotify or other programs.

All of the necessary connections have been outlined in great detail on the previous pages. We urge you to re-read these sections before venturing into recording territory. That said, if you've already been there, done that, and are ready to record, here's a quick primer on getting started.

. PC users: install the latest driver from the Mackie website. Installation instructions are included with the download. Please follow the directions listed on that document for setting up the mixer's USB driver settings. Mac users: no driver required.

2. Turn down all knobs.

3. Disengage all switches.

4. Plug signal sources into the mixer, such as:

• Microphones plugged into the mic inputs. (Engage phantom power if needed.)

• Line-level sources such as keyboards, drum machines, or MP3 players plugged into the line-level inputs.

5. Connect cords from the L/R outputs to powered speakers (or to an amplifier connected to passive speakers).

6. Push a USB cable securely into the mixer’s USB connector and plug the other end into any open USB port of the computer.

7. Turn the mixer on.

8. Turn the computer on.

9. Turn the powered speakers (or amplifiers) on.

0. To set the DL6S or DL32S as the default playback or recording device, open the Sound preferences on the computer and select the DL6S or DL32S.

. If using the DL16S or DL32S with a DAW application, open the DAW and navigate to the DAW sound preferences. Select the DL6S or DL32S as the input and output device. Please refer to your DAW reference guide for additional details.

3. Be sure that the volume of the input is the same as it would be during normal use.

4. Slowly bring up the master fader to a comfortable listening level.

Playback from iTunes or other music apps occurs via the return channels on Master Fader.

Several hookup diagrams are available on the next few pages. These help visually explain the text listed here.

Page 11

Appendix A : Hookup Diagrams

Live Sound: House Engineer

DL16S • DL32S Owner’s Manual

Here’s a pretty common setup utilizing the DL32S. Mics are connected to input channels -6 which may be used to mic up a drum set, guitar and bass cabinets, acoustic guitar, lead and background vocals, a horn section, etc. A pair of synthesizers are connected to channels 25-26 and 27-28 and a couple of axes into inputs 3 and 32, all via /4" input jacks. And there are still an additional 0 unused inputs available for extra mics!

Outputs 9-0 are assigned as the L/R main outs [default]. These connect directly to a pair of Thump8S powered subwoofers which are connected to a pair of Thump5BST powered loudspeakers. Outputs 3-8 are assigned as aux sends -6. These are sent to six separate Thump2A powered loudspeakers set up as monitors for the band. Outputs -2 are sent to transmitters for in-ear monitors.

The house engineer will set the LR main mix, as well as get the multitrack recording of the band’s live show utilizing the multi-plaform device of his/her choice.

Page 12

DL16S • DL32S Owner’s Manual

Live Sound: Self-Engineered

Here’s a setup for all the musicians out there who whine for “more me” in the mix. Set up and connect each musician’s instrument, the PA and monitors just like they would be in any other live situation.

The house engineer’s multi-plaform device of his/her choice is at the bar (right next to a shot and a beer, of course – unseen in the illustration above; afer all, it is a good-sized venue) where he/she will set the LR main mix, as well as get the multitrack recording of the band’s live show.

Up to 20 devices may be connected to the DL6S • DL32S. As such, each band member may control their own mix from their own “station”. As seen in the illustration above, the drummist, bassist, vocalist, keyboardist, DJist and samplerist each have a device. Six musicians, six devices, six-plus outputs (conﬁgured as auxes). Coincidence? We think not. Whining problem solved!

Page 13

Studio Recording

DL16S • DL32S Owner’s Manual

In addition to being live mixers, the DL6S • DL32S also make great mixers for studio recordings.

Start by simply setting up and connecting all the necessary mics, instruments and other inputs.

Next, set the levels and create the mix you desire.

A computer – Mac or PC, your choice! – is connected to the USB connector on the front panel for recording up to 6x6 channels (DL6S) or 32x32 channels (DL32S).

Now listen to your masterpiece via headphones (connected to the phones output jack).

Voilà, you just recorded and played back up to 6x6 or 32x32 channels while sittin’ in your underwear...the only way to write and record!

As much as we like to write and record in our underwear (and urge you to do the same – it’s comfortable!), please save it for the studio. No one’s interested in seeing you play a live gig in your Fruit of the Looms®. Trust us, we did it...once.

Appendix C : Rack Ear Installation Instructions

Introduction

Each DL6S and DL32S mixer arrives with one pair of rack ears set into the packing foam, visible upon opening the box. It allows the mixer to be mounted in a standard 9" rack. A manual Phillips screwdriver is the only tool required for installation.

Procedure

() — Turn o the mixer and disconnect all cords. Place the mixer front side up / rear side down on a sof and dry ﬂat surface.

(2) — Using the Phillips head screwdriver, remove the four screws, washers and corner pieces as shown below

and keep them in a safe place. You don’t need them now, but you may need them again someday.

DL16S • DL32S Owner’s Manual

(3) — Using only the new screws supplied, secure the rack ear brackets to each side of the mixer as shown below. Hand-tighten the screws securely.

As seen above, the rack ears on the DL6S are the same size and interchangeable. In other words, both rack ears work on either side of the mixer. The rack ears on the DL32S, however, dier in size. It is pertinent that you place the “smaller” rack ear on the lef-hand side of the mixer (mixer front facing you); the “bigger” rack ear allows extra space for the power cord and should be attached to the right side of the mixer.

Since we’re still discussing the DL32S, you should know that the side handle needs to be removed, as well. This allows enough space for the mixer to be rack-mounted. Simply use the Phillips head screwdriver to remove the two screws and keep them (and the handle) in a safe place. Like the screws and corner pieces from step 2, you don’t need them now, but you may need them again someday.

(4) — Oer up the mixer to the rack and secure it in place with four rack screws (not supplied).

Appendix E : Service Information

Troubleshooting

If you think your DL6S • DL32S has a problem, please check out the following troubleshooting tips and do your best to conﬁrm the problem. Visit the Support section of our website (www.mackie.com/support) to get some ideas or contact our technical support heroes. You may ﬁnd the answer to the problem without having to send your DL6S • DL32S away.

Here are three useful tips that could correct any of the issues outlined below (or possibly any other issue that we haven’t yet discovered):

(1) — Restart the tablet, phone or computer. Don’t just restart the Master Fader app. Restart the tablet, phone or computer! Completely power it down, then power it back up.

(2) — Restart the mixer. This is especially useful afer ﬁrmware and sofware updates where the mixer and tablet or computer aren’t quite on the same page. A simple reboot can sometimes work great wonders.

(3) — Restart the external router (if connected). Internet disconnectivity got you down? Unplug and re-plug the router. This may resolve any connection issues.

There are no user serviceable parts. If none of these tips work, please refer to “Repair” on the next page to ﬁnd out how to proceed.

DL16S • DL32S Owner’s Manual

No Power

No Sound

• Our favorite question. Is it plugged in? Make sure the AC outlet is live [check with a tester or lamp].

• Our second favorite question. Is the side panel power switch in the ON position?

• Are all the lights out in town? If so, contact the local power company to get power restored.

• Are all the connections good and sound? Make sure all of the connecting cables work and are securely connected at both ends. Try the same source signal in another channel, set up exactly like the suspect channel.

• Is the signal source powered on? Is it working (and making union scale)?

Page 24

DL16S • DL32S Owner’s Manual

Noise / Hum

• Are you using unbalanced cables? Swap them out with balanced cables to see if that ﬁxes the problem.

• Turn the input gains down one-by-one. If the oending noise disappears, it’s either that input or whatever is plugged into it. If you unplug the whatever-is-plugged-into-it and turn the input gain back up and the noise is gone, it’s from your whatever.

• Is phantom power required for the microphone?

• Sometimes it helps to plug all the audio equipment into the same AC circuit so they share a common ground. Make it so.

• Has the band been together long?

No Interwebs

• Read the chapter titled “Wireless Setup” in the Master Fader Reference Guide. This section is very important and reading it cover-to-cover is the best troubleshooting.

• Is your tablet, phone or computer connected to the correct wireless network? Ensure that it didn’t hop onto to a dierent wireless network.

Repair

• Did you select the correct mixer from the tools > devices screen?

• Are you running the latest and greatest Master Fader and DL Series ﬁrmware? Go to Google Play, App Store or Mackie website to check for an update.

• If using an external router, did you connect the Ethernet cable to the correct port? Be sure to use the LAN port and not the WAN port.

• If using an external router, did you connect and power on the router BEFORE turning on the mixer?

• Force quit the Master Fader app.

• If using an external router, try another Ethernet cable.

• If using an external router, try another router.

Appendix F : Glossary Of Terms

The glossary contains brief deﬁnitions of many of the audio and electronic terms and acronyms used in discussions of sound mixing and recording. If you would like more information, we recommend the following:

The Audio Dictionary — Glenn White Tech Terms — Peterson & Oppenheimer Handbook For Sound Engineers — Glen Ballou Pro Audio Reference — Dennis Bohn Sound Reinforcement Handbook — Gary Davis

A/D Converter — Analog-to-digital converter. A device that transforms incoming analog signals into digital form.

AFL — An acronym for Afer Fade Listen, which is another way of saying post-fader solo function.

Attenuate — To reduce or make quieter.

Aux — Short for auxiliary.

Auxiliary — Long for aux. In sound mixers, supplemental equipment or features that provide additional capabilities

to the basic system.

Aux Send — A mixer bus output designed to send a signal to an auxiliary processor or monitor system.

DL16S • DL32S Owner’s Manual

Balanced Input — An input consists of two leads, neither of which is common to the circuit ground. This is a “dierential pair”, where the signal consists of the dierence in voltage between the two leads. Balanced input circuits can oer excellent rejection of common-mode noise induced into the line.

Balanced Output — In a classic balanced audio circuit, the output is carried on two leads (high or + and low or –) which are isolated from the circuit ground by exactly the same impedance.

A symmetrical balanced output carries the same signal at exactly the same level but of opposite polarity with respect to ground.

A special case of a balanced output carries the signal on only one lead, with the other lead being at zero voltage with respect to ground, but at the same impedance as the signal-carrying lead. This is sometimes called impedance balanced.

Bandwidth — The band of frequencies that pass through a device with a loss of less than 3 dB, expressed in Hertz [Hz] or in musical octaves. Also see Q.

Channel — A functional path in an audio circuit: an input channel, an output channel, an FX channel and so on.

Channel Strip — An audio channel consisting of a long, vertical strip.

Clipping — A form of severe audio distortion that results from peaks of the audio signal attempting to rise above the capabilities

of the ampliﬁer circuit. Seen on an oscilloscope, the audio peaks appear clipped o. To avoid clipping, reduce the system gain in or before the gain stage in which the clipping occurs. Also see headroom.

Compressor — This is a dynamic processor used to smooth out any large transient peaks in an audio signal that might otherwise overload your system or cause distortion. The amplitude threshold and other parameters such as attack time, release time, and tire pressure are adjustable.

Condenser — Another term for the electronic component generally known as a capacitor. In audio, condenser ofen refers to a type of microphone that uses a capacitor as the sound pickup element. Condenser microphones require electrical power to run internal ampliﬁers and maintain an electrical charge on the capacitor. They are typically powered by internal batteries or phantom power supplied by the mixer.

Console — Another term for mixer. DL32S mixer = DL32S console.

D/A Converter — Digital-to-analog converter. A device that transforms incoming digital signals into analog form.

dB — See decibel.

Page 26

DL16S • DL32S Owner’s Manual

Glossary Of Terms Continued...

dBu — A unit of measurement of audio signal voltage in an electrical circuit, expressed in decibels referenced to 0.775 VRMS into any impedance. Commonly used to describe signal levels within a modern audio system.

Decibel (dB) — The dB is a ratio of quantities measured in similar terms using a logarithmic scale. Many audio system parameters measure over such a large range of values that the dB is used to simplify the numbers. A ratio of 1000:1 = 60 dB. Since dB is a unitless quantity, it doesn’t matter if it’s volts or dollars. (Just try asking the chief engineer for a 3 dB raise). When one of the terms in the ratio is an agreed upon standard value, such as 1.23 V, 1 V or 1 mw, the ratio becomes an absolute value. For example, +4 dBu, –10 dBV or 0 dBm.

Delay — Delay “delays” the audio signal for a short period of time. Delay can refer to one short repeat, a series of repeats or the complex interactions of delay used in chorusing or reverb.

Dipping — The opposite of peaking, of course, used in audio to describe the shape of a frequency response curve. A dip in an EQ curve looks like a valley, or a dip. Dipping with an equalizer reduces a range of frequencies. (See guacamole).

Doubling — A delay eect where the original signal is mixed with a medium (20 to 50 ms) delayed copy of itself. When used carefully, this eect can simulate double-tracking [recording a voice or instrument twice].

Dry — Dry means without eects. It is just the signal alone; no reverb, no delay, etc.

DSP — Digital Signal Processing accomplishes the same functions found in analog signal processors, but performs them

mathematically in the digital domain, with more precision and accuracy than its analog counterpart. Since DSP is a sofwarebased process, parameters and processing functions are easily changed and updated be revising the Master Fader app.

Dynamic Microphone — The class of microphones that generate electrical signals by the movement of a coil in a magnetic ﬁeld. Dynamic microphones are rugged, relatively inexpensive, capable of very good performance and do not require external power.

Dynamics Processor — A type of processor that only aects the overall amplitude level of the signal (sometimes as a function of its frequency content), such as a gate, compressor, or limiter.

Dynamic Range — The range between the maximum and minimum sound levels that a sound system can handle. It is usually expressed in decibels as the dierence between the level at peak clipping and the level of the noise ﬂoor.

Echo — The reﬂection of sound from a surface such as a wall or ﬂoor. Reverberation and echo are terms that are ofen used interchangeably, but in audio parlance a distinction is usually made: echo is considered to be a distinct, recognizable repetition (or series of repetitions) of a word, note, phrase or sound, whereas reverberation is a diuse, continuously smooth decay of sound.

EIN — Equivalent Input Noise. A speciﬁcation that helps measure the “quietness” of a gain stage by deriving the equivalent input noise voltage necessary to obtain a given preamp’s output noise. Numerically, it’s the output noise at a given gain setting minus the gain. EIN is usually measured at a maximum gain and typically ranges from -125 to -130 dBu.

EQ — Short for equalization.

EQ Curve — A graph of the response of an equalizer, with frequency on the x (horizontal) axis and amplitude (level)

on the y (vertical) axis. Equalizer types and eects are ofen named afer the shape of the graphed response curve, such as peak, dip, bell and shelf.

Equalization — Long for EQ. Equalization refers to purposefully changing the frequency response of a circuit, sometimes to correct for previous unequal response (hence the term, equalization), and more ofen to boost or cut the level at certain frequencies for sound enhancement, to remove extraneous sounds, or to create completely new and dierent sounds.

A lot of how we refer to equalization has to do with what a graph of the frequency response looks like. A ﬂat response (no EQ) is a straight line; a peak looks like a hill, a dip is a valley, a notch is a really skinny valley, and a shelf looks like a plateau (or shelf). The slope is the grade of the hill on the graph.

Fader — Another name for an audio level control.

Page 27

Glossary Of Terms Continued...

Filter — A simple equalizer designed to remove certain ranges of frequencies. The high-pass ﬁlter attenuates frequencies below its cuto frequency.

FOH — Front Of House. See house and main (house) speakers. No engineer ever goes to the BOH because there’s never enough time to drink beer.

Frequency — The number of times an event repeats itself in a given period of time. Generally, the time period for audio frequencies is one second, and frequency is measured in cycles per second, abbreviated Hz, honoring Dr. Heinrich Hertz (who did not invent the rental car company). One Hz is one cycle per second. One kHz (kilohertz) is 1000 cycles per second.

The audio frequency range is generally considered to be 20 Hz to 20,000 Hz (or 20 kHz). This covers the fundamental pitch and most overtones of musical instruments.

Gain — The measure of how much a circuit ampliﬁes a signal. Gain may be stated as a ratio of input to output voltage, current or power, such as a voltage gain of 4, or a power gain of 1.5, or it may be expressed in decibels, such as a line ampliﬁer with a gain of 10 dB.

Gain Stage — An ampliﬁcation point in a signal path, either within a system or a single device. Overall system gain is distributed between the various gain stages.

DL16S • DL32S Owner’s Manual

Gate — A dynamics processor that automatically turns o an input signal when it drops below a certain level. This can reduce the overall noise level of your mix by turning o inputs when they are not in use. Threshold, attack time, hold, and release time are some of the adjustable gate parameters.

Graphic EQ — The graphic equalizer uses sliders for its boost / cut controls, with its operating frequencies evenly spaced through the audio spectrum. In a perfect world, a line drawn through the centers of the control shafs would form a graph of the frequency response curve. Or, the positions of the sliders give a graphic representation of boost or cut levels across the frequency spectrum.

Ground — Also called earth. Ground is deﬁned as the point of zero voltage in a circuit or system, the reference point from which all other voltages are measured.

In electrical power systems, ground connections are used for safety purposes, to keep equipment chassis and controls at zero voltage and to provide a safe path for errant currents. This is called a safety ground. Maintaining a good safety ground is essential to preventing electrical shock. Follow manufacturer’s suggestions and good electrical practices to ensure a safely grounded system. Never remove or disable the grounding pin on the power cord.

In sensitive electronic equipment, tiny currents and voltages riding on the ground (so it’s not truly zero volts) can cause noise in the circuits and hamper operation. Ofen a ground separate from the power ground is used as the reference point for the electronics, isolating the sensitive electronics from the dirty power ground. This is called a technical ground.

Quality audio equipment is designed to maintain a good technical ground and also operate safely with a good safety ground.

Ground Loop — A ground loop occurs when the technical ground within an audio system is connected to the safety ground at more than one place. This forms a loop around which unwanted current ﬂows, causing noise in the audio system. Never disable the safety ground in an attempt to solve hum problems.

Guacamole — A delicious dip comprised mostly of avocados. Speaking of dips, refer to dipping.

Hertz — The unit of frequency, equal to 1 cycle per second. 1000 Hz equals 1 kHz.

House — In audio-land, the house refers to the systems (and even persons) responsible for the primary sound reinforcement

in a given venue. Hence, we have the house mixer or house engineer, the house mix, house mix amps, main house speakers, etc.

Hz — Short for Hertz.

Page 28

DL16S • DL32S Owner’s Manual

Glossary Of Terms Continued...

Impedance — The A.C. resistance, capacitance, and inductance in an electrical circuit, measured in ohms [ ]. In audio circuits (and other AC circuits) the impedance in ohms may ofen be much dierent from the circuit resistance as measured by a DC ohmmeter.

Maintaining proper circuit impedance relationships is important to avoid distortion and minimize added noise. Our input and output impedances are set to work well with the vast majority of audio equipment.

Knee — A knee is a sharp bend in a compressor gain curve, not unlike a sharp bend in your leg.

Level — Another word for signal, voltage, power, strength or volume. Audio signals are sometimes classiﬁed according

to their level. Commonly used levels are: microphone level (–40 dBu or lower), instrument level (–20 to –10 dBu), and line level (–10 to +30 dBu).

Line Level — A signal whose level falls between –10 dBu and +30 dBu.

Main (House) Speakers — The main loudspeakers for a sound reinforcement system. These are usually the largest and loudest

loudspeakers, positioned facing the audience; the sound is typically delivered from the stage. This is also called the PA.

Mains — Short for main or house speakers in a sound reinforcement system.

Master — Me. I am your master. Obey! The master on the Master Fader app, though, refers to the master fader.

It aects the total level of the selected output in which one or more signals are mixed together.

Mic Amp — See Mic Preamp.

Mic Level — The typical level of a signal from a microphone. A mic level signal (usually – but not always – coming from

a microphone) is generally lower than –30 dBu. With a very quiet source [a pin dropping?] the signal may be –70 dBu or lower.

Some microphones, notably vintage or vintage-style condenser mics, deliver a higher signal level than this for the same sound pressure level. A “hot” mic output level isn’t necessarily a measure of the microphone’s quality; it’s just an option that the designer(s) chose.

Mic Pre — Short for Mic Preamp.

Mic Preamp — Short for microphone preampliﬁer. An ampliﬁer whose job is to bring the very low microphone level signal

up to line level, or in the case of a mic preamp built into a mixer, the mixer’s internal operating level [approximately 0 dBu].

Mic preamps ofen have their own volume control, called gain, to properly set the gain for a particular source. Setting the mic preamp gain correctly is an essential step in establishing good signal-to-noise ratio and sucient headroom. The DL Series mixers are ouﬁtted with Onyx mic preamps.

Mixer — An electronic device used to combine various audio signals into a common output. Dierent from a blender, which combines various fruits and alcohol into a common libation.

Monaural — Long for mono. Literally, pertaining to or having the use of only one ear.

In the audio ﬁeld, monaural describes a signal or system which carries audio information on a single channel with the intent of reproducing it from a single source. One microphone is a mono source; many microphones mixed to one channel is a mono mix; a stereo (or – to be picky – a two-channel) mix of many microphones panned lef and right is a stereo mix of mono sources.

Monaural listening, and therefore mono compatibility of a stereo mix, is more important than you might realize. Most people hear television audio and clock radios in mono.

Monitor — In sound reinforcement, monitor speakers [or monitor headphones or in-ear monitors] are used by performers to hear themselves. In the video and broadcast world, monitor speakers are ofen called foldback speakers. In recording, the monitors speakers are those used by the engineer and production sta to listen to the recording as it progresses. In zoology, the monitor lizard is the lizard that observes the production sta as the recording progresses. Keep the lizard out of the mixer.

Mono — Short for monaural (and mononucleosis for that matter).

Mute Groups — Mute groups allow you to quickly mute (and unmute) multiple channels and/or outputs with a single tap. There are a multitude of possibilities in which to assign and enable mute groups: productions featuring a rotating cast of musicians, theater productions, a house of worship and more. It is also great for muting all inputs during song breaks or in-between sets. You may create as many as four separate mute groups with Master Fader.

Noise — Whatever you don’t want to hear. This could be hum, buzz or hiss; or it could be crosstalk, digital hash, or your neighbor’s stereo; or it could be white noise, pink noise or brown noise. It’s also how your parents describe your band. Afer all, it’s what they don’t want to hear.

Noise Floor — The residual level of noise in any system. In a well-designed mixer (such as the DL Series mixers), the noise ﬂoor will be a quiet hiss, which is the thermal noise generated by electrons bouncing around in resistors and semiconductor junctions. The lower the noise ﬂoor and the higher the headroom, the more usable dynamic range a system has.

Nyquist Sampling Theorem — This theorem states that, when an analog signal is converted to a digital signal, it must be sampled at a frequency that is at least twice the highest audio frequency present in the analog signal. If the audio frequency should exceed one-half the sampling frequency, aliasing may result. Thus, if an analog-to-digital converter is sampling at 44.1 kHz, the audio signal should not exceed 22.05 kHz.

PA — Acronym for Public Address. Today, people who work with PA systems like to say they’re working in “sound reinforcement”. See SR.

Pan — Pan sliders are used to position (or even dynamically move) a monaural sound source in a stereo mixing ﬁeld by adjusting the source’s volume between the lef and right channels. Our brains sense stereo position by hearing this dierence in loudness when the sound strikes each ear, taking into account time delay, spectrum, ambient reverberation and other cues.

Peaking — The opposite of dipping. A peak is an EQ curve that looks like a hill, or a peak. Peaking with an equalizer ampliﬁes a band of frequencies.

PFL — An acronym for Pre-Fade Listen. Broadcasters call it cueing. Sound folks call it being able to solo a channel with the fader down.

Phantom Power — A system of providing electrical power for condenser microphones (and some electronic pickup devices) from the microphone input jack. The system is called phantom because the power is carried on a standard microphone audio wiring in a way that is “invisible” to ordinary dynamic microphones. The DL Series mixers use a standard +48 volt DC power, switchable on or o.

Generally, phantom power is safe to use with non-condenser microphones, as well, especially dynamic microphones. However, unbalanced microphones, some electronic equipment (such as some wireless microphone receivers) and some ribbon microphones can short out the phantom power and be severely damaged.

Phase — The time relationship between two signals, expressed in degrees around a circle. 0˚ and 360˚ represent an in-phase relationship. Both signals change in the same way at the same time. Anything else is out of phase.

180˚ out-of-phase is a special case which, for a continuous waveform, means that at any given time the two signals have the same amplitude but are opposite in polarity. The two legs of a dierential output are 180˚ out-of-phase. The polarity invert button (found in the EQ view) reverses the signal polarity.

When out-of-phase signals are mixed, there will be some cancellation at certain frequencies, the frequencies and the degree of cancellation being a function of the amount of phase shif and the relative amplitude of the signals. Attention to mic placement and careful listening will allow you to use this eect creatively.

Post Fader — A term used to describe an aux send (or other output) that is connected so that it is aected by the setting of the associated channel fader. Sends connected this way are typically (but not always) used for eects. A post-fader output from a mixer channel is usually post-EQ.

Pre DSP — Pre DSP is ideal when using the auxes for monitor mixes and you want compression and other eects in the main mix, but not the monitors. Pre DSP is available in all auxes, but not the FX.

Pre Fader — A term used to describe an aux send (or other output) that is connected so that it is not aected by the setting of the associated channel fader. Sends connected this way are typically (but not always) used for monitors.

Q — A way of stating the bandwidth of a ﬁlter or equalizer section. An EQ with a Q of .75 is broad and smooth, while a Q of 10 gives a narrow, pointed response curve. To calculate the value of Q, you must know the center frequency of the EQ section and the frequencies at which the upper and lower skirts fall 3 dB below the level of the center frequency. Q equals the center frequency divided by the dierence between the upper and lower 3 dB-down frequencies. A peaking EQ centered at 10 kHz whose –3 dB points are 7.5 kHz and 12.5 kHz has a Q of 2.

Reverberation, Reverb — The sound remaining in a room afer the source of sound is stopped. It’s what you hear in a large tiled room immediately afer you’ve clapped your hands.

Reverberation and echo are terms that are ofen used interchangeably, but in audio parlance, a distinction is usually made: reverberation is considered to be a diuse, continuously smooth decay of sound, whereas echo is one or more distinct, recognizable repetitions of a word, note, phrase or sound which decreases in amplitude with every repeat.

Highly reverberant rooms are called live; rooms with very little reverberation are called dead. A sound source without added reverb is dry; one with reverb added is wet.

RFI — Radio Frequency Interference. High frequency radiation that ofen results from sparking circuits. This may be manifested in a number of ways in audio systems, but is usually evident as a high-frequency buzz or harsh sound.

RMS — An acronym for root mean square, a conventional way to measure the eective average value of an audio signal or other AC voltage. Most AC voltmeters are calibrated to read RMS volts, though on many meters that calibration is accurate only if the waveform is sinusoidal.

Sampling Frequency — This is the rate at which an analog signal is sampled during the analog-to-digital conversion process. The sampling rate used for CDs is 44.1 kHz, but professional recordings are ofen sampled at higher sample rates.

Send — A term used to describe the output of a secondary mix of the input signals, typically used for monitors, headphone amp or eects devices. These are the aux sends on the DL Series mixers.

Shelving — A term used to describe the shape of an equalizer’s frequency response. A shelving equalizer’s response begins to rise (or fall) at some frequency and continues to rise (or fall) until it reaches the shelf frequency, at which point the response curve ﬂattens out and remains ﬂat to the limits of audibility. If you were to graph the response, it would look like a shelf. Or more like a shelf than a hiking boot. See also peaking and dipping.

Signal-to-Noise (S/N) — This is a speciﬁcation that describes how much noise an audio component has compared to the signal. It is usually expressed in dB below a given output level. The S/N of the DL Series mixers is 92 dB.

Solo — Italian for alone. Solo allows you to listen to individual channels singly or in combination with other soloed signals.

Sound Reinforcement — A system of amplifying acoustic and electronic sounds from a performance or speech so that a large

audience can hear clearly. Or, in popular music, so that a (hopefully) large audience can be excited, stunned, or even partially deafened by the tremendous ampliﬁcation. Sound reinforcement means essentially the same thing as PA [Public Address].

Spaghetti — That mess of wires and cables in the back of your rack and/or console. You really can tame this beast.

SR — An acronym for Sound Reinforcement, which refers to the process (or a system for) amplifying acoustic and electronic

sounds from a performance or speech so that a large audience can hear clearly. Or, in popular music, so that a (hopefully) large audience can be excited, stunned, or even partially deafened by the tremendous ampliﬁcation. Sound reinforcement means essentially the same thing as PA [Public Address].

Stereo — Believe it or not, stereo comes from a Greek word that means solid. We use stereo or stereophony to describe the illusion of a continuous, spacious sound ﬁeld that is seemingly spread around the listener by two or more related audio signals. In practice, stereo ofen is taken to simply mean two channels.

Tinnitus — The ringing in the ears that ofen results from prolonged exposure to very loud sound levels.

TRS — Acronym for Tip-Ring-Sleeve, the three parts of a two conductor (plus shield) phone plug. Since the plug or jack

can carry two signals and a common ground, TRS connectors are ofen referred to as stereo or balanced plugs or jacks.

TS — Acronym for Tip-Sleeve, the two parts of a single conductor (plus shield) phone plug. TS connectors are sometimes called mono or unbalanced plugs or jacks. A 1/4" TS phone plug or jack is also called a standard phone plug or jack.

Unbalanced — An electrical circuit in which the two legs of the circuit do not have the identical impedance to ground. Ofen one leg is also at ground potential. Unbalanced circuit connections require only two conductors (signal “hot” and ground). Unbalanced audio circuitry is less expensive to build, but under certain circumstances is more susceptible to noise pickup.

View Groups — View groups allow you to see only the channels that you want to view, hiding the rest. This improves organization and allows for faster navigation. You may create and assign as many as four separate view groups with Master Fader.

Volume — The sound level in an audio system. Perhaps the only thing that some bands have too much of.

DL16S • DL32S Owner’s Manual

VRMS — Acronym for Volts Root Mean Square. See RMS.

Wet — A signal with added reverberation or other eect like echo, delay or chorusing.

XLR Connector — Three-pin connectors now universally used for balanced microphone connections. Also known as Cannon,

as Cannon was the original manufacturer of this type of connector. In sound work, a Cannon connector is taken to mean a Cannon XLR-3 connector or any compatible connector. You can tell who the audio geezers are when they refer to XLR connectors as Cannon connectors.

Z — The electrical symbol for impedance.

Zymurgy — The science of brewing, an important part of our technology and history. We needed something other than just

a plain ‘ol “Z” to end the glossary.
