Owners Manual

Controls & Connection

Front Panel

1 – USB Connector

USB 1.0 port for connection to a PC running Windows XP or Vista. With a connected PC you may run the DC-One Editor Graphic User Interface Application. The DC-One can be operated, edited and configured for installation with an easy to use, intuitive interface. Any available firmware updates downloadable from www.electrovoice.com can be loaded via the USB port as well; allowing for easy in-field updates.

2 – Input Level Meters

The DC-One does not itself have input level controls. Proper input level adjustment is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer (or other audio output device), as the vast majority of today’s mixer-outputs are dBu calibrated. When the mixer is operating at optimal levels, so is the DC-One. The input meters monitor the input level of either analog or AES-EBU inputs, depending on the input mode selection set in the Setup Menu.

Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +3dBu (green) and / or +6dBu (Yellow) LED indicators. As the DC-One is a digital audio device – and digital clipping produces very unpleasant results, the Clip (red) LED should not light. If the DC-One’s input does clip, reduce the output level of the connected mixer.

3 – LCD Display

The back-lit, 192 x 32 graphic LCD display allows for operation and editing of the DC-One without the need for an attached PC. The contrast can be set in the Setup Menu for varying lighting conditions and viewing angles.

The LCD display works in conjunction with Menu buttons, Select buttons and Value buttons - to operate, navigate and edit the DC-One’s parameters.

In Run mode, the LCD displays the number and name of the currently selected factory or user preset. Pressing the Recall or Store buttons switches to their respective menus. Pressing the Edit or Setup menu buttons switches the display to the last edited parameter.

In Edit and Setup mode, the top line of the LCD display shows the currently selected parameter edit screen. Use the Select buttons to activate the top line of the display, and the value buttons to scroll through available parameter edit screens.

Edit / Setup – Scroll forwards/backwards through Edit / Setup screens when the top line of the LCD screen is active. Scroll forwards through values for the selected parameter in an Edit / Setup screen.

6 – Edit / Compare Button

Pressing the Edit button while in Run mode places the current preset in Edit mode and the Edit button lights. The LCD display shows the last edit screen that was selected. From this point, any edit screen can be displayed and altered.

Pressing the Edit button again “compares” the edited preset, if parameters have been altered, to the original un-edited preset. This compare function will audibly switch between the altered parameters and the previously stored settings, allowing you to hear the effect of any DSP changes that have been made. Use this feature to monitor progress in editing or creating presets.

Subsequently recalling a new preset will prompt you to save changes, which you may do or not.

7 – Setup Button

Pressing the Setup button while in Run mode displays the Setup menus in the LCD display and the Setup button lights. In this mode, any Setup menu can be displayed and altered. Changes made to Setup menu items are saved automatically.

To exit Setup mode, press the Setup button again. The LCD display will revert to Run mode.

19 – Output Level Button

Pressing the Level button places the current preset in Edit mode and jumps to the Output Channel Level screen. Subsequent button presses step through the six output channels.

20 - Output Level Meters

Each output channel has an eight-segment output level VU meter. Meter response characteristics can be selected in the Setup menu: Normal Fast, Peak-Hold Slow Decay. The yellow segment indicates that limiting is being applied to the output channel. The red segments indicates clipping of the D/A converters and should be avoided by adjusting the Output Level of the output channel. It is important to understand how the meters work and what they are displaying. The Output Meters are displayed as “dB to Limiter Threshold”. In other words, these meters will display the headroom between the output level and the limiter threshold. When viewed in conjunction with the Gain Reduction meters, this provides a complete display of level and headroom before and after limiting has been engaged to allow system levels to be optimized.

This also means that the output metering will be displayed differently depending on the limiter threshold setting.

21 – Output Gain Reduction Meters

Each output channel has a four-segment gain reduction meter that shows the effect of the output channel Limiter on output level; from 0dBu to -12dBu.

22 – Output Channel Mute Buttons

Each output channel has a lighted Mute button. Pressing the Mute button turns off the output of that channel. The button lights red as an alert. Press the Mute button again to restore the output channel’s signal.

Output channels may also be muted from the DC-One Graphic User Interface Application, if the unit is connected to a PC. Muting a channel in any window of the application will light the channel Mute button on the front panel of the unit as well.

Owners Manual

23 – Output Channel Function Indicators

Each output channel has a four-segment function display for informational purposes only. For any given configuration possible with the DC-One, an output channel may be identified as a sub, low, low/mid, mid, mid/hi, hi or full range output. One or two adjacent LED are displayed to indicate all possible output bandpasses. (Full range is indicated by no lit LED’s.)

Rear Panel

24- A.C. Inlet

The DC-One features a standard IEC A.C. inlet that will accept universal power cords. The DC-One power supply is auto-ranging and can accept voltages from 100 - 240VAC, 50 – 60Hz. Only A.C. cords approved for use in your country should be connected to the DC-One.

25 – A.C. Fuse

The A.C. inlet includes a fuse holder that contains the mains fuse as well as a spare fuse. If necessary, replace the fuse only with a specified 5x20mm, T800mA, L250V replacement. Disconnect A.C. power before replacing a fuse. Before turning the unit back on, assess the condition of the A.C. receptacle powering the DC-One. If fuses continue to blow, refer servicing of the DC-One only to qualified service personnel.

26 – A.C. Power Switch

The A.C. power switch turns power to the DC-One On and Off.

27 – Link/Relay Interface

The operating mode of this dual purpose interface is selected in the Setup menu. Operating modes are:

RS-232 Interface – Used to link two DC-Ones together in a Master / Slave setup. Connection is made via a standard 9-pin null-modem serial interface cable with female connectors.

Contact Closure Port – Eight contact closure pins plus ground for interfacing to 5v contact closure systems. Each pin can be assigned a preset that is recalled when voltage on that pin is detected. The lowest pin number takes priority in multiple controller systems.

28 – Balanced XLR Outputs

Each output channel has an electronically balanced XLR connector for connection to system amplifiers. Each output channel can output different frequency ranges depending on its assignment and cross-over settings.

Care must be taken to assure that each output is connected to an appropriate amplifier and loudspeaker to avoid damage or unexpected results. Note that a new preset may change the assignment of channel and its frequency range. For instance an output assigned to Hi frequency speakers in one preset, may be assigned as a sub output in another. See chapter “Configurations of the DC-One” for connection examples.

29 – AES/EBU Digital Input

In addition to the analog audio inputs, an AES/EBU digital stereo input is provided and selectable in the Setup menu. The input conforms to IEC standard 60958 Type I. Connections must be made with three-conductor, 110-Ohm, twisted pair cabling and an XLR connector.

30 – Balanced XLR Thru

Each analog audio input is connected to an electronically buffered and balanced output as a through connector. The signal does not go undergo any digital conversion or processing. These connectors are used to pass input audio to a second DC-One used as a slave or to other audio inputs in the system.

31 – Balanced XLR Inputs

Each input has an electronically balanced, locking XLR connector. In stereo or dual modes, connections to both inputs must be made. In mono modes, only one connection need be made, typically to Input A.

32 – -6dB Pad

Input levels to the DC-One can be reduced -6dB prior to the A/D converter to compensate for higher-level output from mixers and other audio devices. For ideal signal to noise performance when connecting the DC-One to high output level devices engage the -6dB pad rather than turning down the output of the connected device. The DC-One’s Input Level Meters (2) will indicate incoming signal level and whether attenuation is required.

Owners Manual

Installation

For proper operation, all directions regarding installation and connection must be followed.

Mounting

The DC-One should be mounted in a rack-mount enclosure or rack rails. The unit is 1RU tall by 14” (353mm) deep. Proper clearance for air circulation around the unit must be provided. Do not block any vent holes on the unit. For secure mounting and electrical insulation, correct rack screws must be used – #10-32 screw with plastic / nylon cup washer. All four mounting points provided by the rack ears must be secured.

Power Connection

The DC-One must be connected to A.C. power only by means of the provided IEC A.C. cable or by a power cable provided by the dealer / installer to match the configuration of your country or region. The DC-One must only be connected to a properly wired, three pin, grounded A.C. outlet. A.C. power must range from 100 – 240VAC, 50 – 60Hz. The DC-One internal power supply is an auto-ranging design; no adjustments are necessary to configure it for proper A.C. power.

Audio Cables

Always use correctly shielded audio cables when connecting to the DC-One.

Balance Input / Output Connections

To minimize induced noise caused by audio cables and to maximize the length of cables used, balanced connections are strongly advised for both Inputs and Outputs. The XLR jacks provided on the DC-One are configured as pin 1 ground, pin 2 hot (+), pin 3 cold (-). Cable shielding must be connected to pin 1. XLR – XLR cables or ¼” tip-ring-sleeve – XLR cables can both be used for balanced connections to the DC-One.

Un-balanced Input / Output Connections

Un-balanced connections can be made to the DC-One, although induced noise from cabling may be increased. Cables should also be less than 15” (5m) in length. Unbalanced connections can be 6dB lower in level as well. To match the audio level obtained with a balanced connection, it is necessary to tie pin 3 to ground at the XLR connector. This may increase noise.

RS-232

Two DC-Ones can be used in combination as a Master / Slave for managing larger sound reinforcement systems. A 9-pin D-sub connector is provided on the rear of each unit for data line connections. A standard female-to-female RS232 cable that conforms to the null modem wiring convention is used to connect the two units. Cable length should be kept to less than 45 feet (15m) for the most reliable operation. These cables are readily available at local computer dealers.

Operation of the DC-One 9-pin port for RS-232 connections is selected in the Setup menu.

Relay Contact Closure

The same 9-pin port used for RS-232 connection to another DC-One can alternately be used to recall presets from relay contact closures. Pins 1 – 8 are the input lines and pin 9 provides the ground reference. When the DC-One detects a connection between pin-9 ground and pins 1 – 8, as completed by an external relay, a preset assigned by the user to pins 1-8 is recalled into memory and the DC-One returns to runtime mode.

Owners Manual

USB

Connecting the DC-One to a PC for operation via the DC-One Graphic User Interface application is accomplished via the front panel USB port. The port conforms to the USB 1.0. Type B specification. Type B USB cables are readily available at computer dealers.

Connection to Amplifiers

It is very important to confirm correct connection to all amplifiers. The DC-One has the ability to configure each output for a specific frequency range; sub, low freq. mid freq, high freq. You must make sure that each output is connected to the correct amplifier and loudspeaker(s). Incorrect connections could lead to unexpected results or damage to loudspeaker components.

Note also that each preset in the DC-One includes DSP and bandpass parameters for the output channels. It is possible for a new preset to change an output from Hi to Sub, for instance. Make sure that connections to amplifiers and loudspeakers are correct before using a new preset.

Input Level Adjustment

The final step in setting up, installing and connecting the DC-One is to set proper input levels to the unit. The DC-One does not itself have input level controls. Proper input level setting is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer (or other audio output device). The input meters monitor the input level of either analog or AES/EBU inputs, depending on the input mode selection set in the Setup Menu.

Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +3dBu (green) and / or +6dBu (Yellow) LED indicators. As the DC-One is a digital audio device – and digital clipping produces very unpleasant results – the Clip (red) LED should never light. If it does, reduce the output level of the connected mixer.

Input levels to the DC-One can be reduced -6dB with the rear panel pad switch to compensate for higher-level output from mixers and other audio devices. For ideal signal to noise performance when connecting the DCOne to high output level devices, engage the -6dB pad rather than turning down the output of the connected device.

Editing & Operation

Factory Presets

The DC-One comes with 60 factory presets to configure and manage typical sound reinforcements systems. Factory presets can be recalled at will. Limited editing can be performed from the front-panel LCD user interface such as output level, mute and limiter threshold setting. Installers can identify factory presets with system configurations that are not appropriate for the given installation and lockout and hide them from the operator.

User Presets – Standard Editing

The DC-One uniquely allows for limited access to and visibility of parameters. Via the DC-One Graphic User Interface Application, the installer can determine which parameters may be accessed.

For more on Standard and editing see page 22.

User Preset – Full Editing

The DC-One can also be configured in full-edit mode. All matrix routing presets are available including 2 x 6 Full Edit. All DSP parameters are accessible and adjustable. Resulting settings can be saved into 20 User Preset locations for later recall. Editing can be performed from the front-panel LCD display or on a PC with the DC-One Editor Graphic User Interface Application. Full editing is recommended only for experienced installers / operators.

Owners Manual

Run-time Mode

LCD Display

On power-up, the DC-One boots and displays the run-time screen. The current preset memory location and name are displayed as well as the configuration on which the preset is based.

Caution Before operating the sound reinforcement system, and any time a new preset is

recalled, check the configuration display to make sure that it is appropriate for your system and that connections to your system are correct for the current configuration. Failure to do so could cause unexpected results or damage to the system or its components.

The LCD display’s contrast can be adjusted in the Setup Menu to accommodate different viewing angles.

Input Level Meters

During operation, the left and right input level meters display the signal present at the DC-One’s analog and Digital inputs. The DCOne does not itself have input level controls. Proper input level setting is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer or other audio source.

Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +3dBu (green) and / or +6dBu (yellow) LED indicators. As the DC-One is a digital audio device – and digital clipping produces very unpleasant results – the Clip (red) LED should never light. If it does, reduce the output level of the connected mixer.

Output Level Meters

Each output channel has an eight-segment output level VU meter. Meter response characteristics can be selected in the Setup menu: Normal Fast, Peak-Hold or Slow Decay. The yellow segment indicates that limiting is being applied to the output channel. It is important to understand how the meters work and what they are displaying. The Output Meters are displayed as “dB to Limiter Threshold”. In other words, these meters will display the headroom between the output level and the limiter threshold. When viewed in conjunction with the Gain Reduction meters, this provides a complete display of level and headroom before and after limiting has been engaged to allow system levels to be optimized. This also means that the output metering will be displayed differently depending on the limiter threshold setting.

Standard Edit Mode

The DC-One defaults to Standard Edit mode wherein, input and output channel parameters are appropriately linked. (Refer to “Configurations” illustrations to see which channels are parameter-linked for each configuration.

Linked parameters are always identical in value. For instance, setting a graphic eq curve for Input A, sets the same curve for Input B, if the configuration has linked stereo inputs. Either input channel can be edited; changes will be reflected in both. The same is true for parameters of linked output channels. The only exception to the linking of parameters is the Mute buttons. Output channels can be individually muted at any time, either from the DC-One front panel or the Graphic User Interface application.

Full Edit Mode

In the Setup menu, the edit mode can be changed to Full Edit. In Full Edit, no parameter links are enforced, regardless of the configuration selected. Any parameter can be changed without any effect on other parameter values.

Input Channel Hi-Pass Filter

Use the < Select > buttons to make the top line of the Edit screen active and the Value Up and Down buttons to navigate to the Input Hi-Pass screen.

The first DSP block in the DC-One’s signal flow is the stereo Hi-Pass Filter. In any sound reinforcement system, the Hi-Pass filter is crucial for maximizing the efficiency and performance of the PA system. Both analog and digital audio sources can include significant sub-sonic (infra-sonic) program material and artifacts. Audio frequencies below the threshold of human hearing can still be present at the amplifier inputs, and the amplifiers and loudspeakers will do all they can to reproduce to reproduce them; at a great cost of power and efficiency.

Hi-Pass filters can set a frequency, below which, signals will be attenuated or reduced. The cut-off frequency selected for the hi-pass filter – below which the frequencies will be attenuated - will vary depending on the program material and connected loudspeaker system. For example, full range music can produce frequencies down to the theoretical limit of human hearing (20 Hz), some acoustic music can be limited to frequencies above 60 Hz, and voice-only reproduction is limited to much higher frequencies. Hi-pass filter applications and settings will be determined by the needs of the given DC-One preset selected for the program material and sound reinforcement system.

HPF

For detailed EQ plot images please see page 45

The DC-One Hi-pass filter offers several response curves, or slopes, to suit the needs of the given application. Select the curve that best meets the needs of your particular situation:

Freq - The cut-off frequency for the Hi-Pass filter. The frequency range is from 20 Hz to 200 Hz and is adjustable in 1 Hz increments. Select the frequency setting that is appropriate for the attenuation slope selected and type of program material.

Bypass – No sub-sonic or low-frequency filtering is applied. Use this to bypass the Hi-Pass filter.

Slp - Slope or degree of attenuation.

6dB/Oct – A very gentle attenuation of frequencies below the

selected cut-off frequency; good for acoustic music that is generally within known frequencies, but may drop below; without much energy.

12dB/Oct – Steeper attenuation of frequencies below the selected cut-off frequency; useful when un-expected lowfrequency material may be encountered. When 12dB/Oct is selected, Q band is available - from 1.4 to 2.0.

Input Channel Parametric EQ

Use the < Select > buttons to make the top line of the Edit screen active and the Value Up and Down buttons to navigate to the Input PEQ screen.

The DC-One provides a stereo nine-band multi-mode filter generically referred to as the Input PEQ (Parametric Equalizer). The Input PEQ is a very powerful and complex set of multi-mode filters. Care must be given configuring these filter bands, as they interact and can produce unexpected results. Using the DC-One Editor PC application is strongly recommended to set all but the most simple eq curves.

Each band of the Input PEQ can be configured for a specific filter mode, frequency, slope or Q and gain setting. Attention must be paid to the ultimate output gain through the rest of the DC-One’s audio path, as it is possible to boost frequency ranges to the point where the internal or external audio paths of the system may be clipped. Monitoring the output VU meters of the DC-One’s output channels will indicate internal clipping; the input meters of connected amplifiers should do the same.

To bypass any band of the DC-One’s Input PEQ multi-mode filter bank, set the desired band’s gain to 0.0dB. This will have the effect of bypassing the selected filter band.

PEQ

For detailed EQ plot images please see page 45

The following section details the type of filters that can be selected for each of the Input PEQ’s 9 bands and their parameters:

Low-shelf

The Low-shelf filter is a “hinge” type; in that frequencies below its frequency setting can be boosted or cut; hinging on the cut-off Frequency. The amount of boost or cut (Gain), and the extent of width of the filter’s transition band (Slope), are determined by the low-shelf filter’s settings. (See Response/Q and Gain.)

Use the < Select > buttons to navigate to the filter setting you wish to adjust, and the Value Up and Down buttons to alter these settings. Press the Value Up and Down buttons once to increment values by one unit, or press and hold to scroll rapidly through available values. (Values do not wrap around.)

Hi-shelf

The Hi-shelf filter is a “hinge” type; in that frequencies above its frequency setting can be boosted or cut; hinging on the cut-off Frequency. The amount of boost or cut (Gain), and the width of the filter’s transition band (Slope), are determined by the hi-shelf filter’s settings. (See Response/Q and Gain.)

Owners Manual

For detailed EQ plot images please see page 44

PEQ

PEQ is shorthand for Parametric Equalizer. A parametric equalizer has three parameters that determine the frequencies that are affected by it; Center Frequency, Q (filter-width) and Gain. Parametric filters are ideal for identifying, isolating and correcting problematic frequency ranges.

The Frequency parameter determines the center of a range of frequencies that will be adjusted by the PEQ. The Q parameter will determine the range of frequencies adjacent to the center frequency that will also be effected; the greater the value, the smaller the range of adjacent frequencies that will be effected. The gain parameter determines the amount of boost or cut that is applied to the frequencies that are affected by the filter.

Low -pass

The Low-Pass filter determines the ultimate high frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. The low-pass filter is useful for reducing excessive high frequency energy that can create stress on high frequency transducers and listener fatigue.

Available parameters are Frequency and Slope. The frequency parameter determines the frequency above which frequencies will be attenuated. The slope determines how quickly frequencies above the cut-off frequency will be attenuated. (See response curve.)

For detailed EQ plot images please see page 45

Hi-pass

The Hi-Pass filter determines the ultimate low frequency that your sound reinforcement system is allowed to reproduce; given the capabilities of amplifiers, speakers and transducers. Keep in mind that the DC-One signal path already includes a hi-pass filter prior to the Input PEQ DSP block. Settings to this filter in most configurations may be redundant or interactive with the initial HiPass filter.

Available parameters are Frequency and Slope. The frequency parameter determines the frequency below which frequencies will be attenuated. The slope determines how quickly frequencies below that will be attenuated. (See response curve.)

Input Delay

DC-One offers an input delay that is useful for compensating for different arrival times of sound originating from loudspeakers that are closer or further away from the listener than others. A technique known as the Haas Effect allows the operator to create the illusion that

Available Input Delay parameters are Delay, Units and Bypass. The Delay parameter allows the user to determine the Delay time values (-200.00ms to +700.00ms.) and the Bypass parameter simply toggles between On/ Off.

To access the Input Delay, press the Delay button found on the input processing menu. Subsequent button presses will toggle the display between Input A and Input B. Input delay parameters are accessed using the <SELECT> button to navigate between Delay and Bypass using the VALUE up/down keys to adjust values.

Routing

Input selections (In-A, In-B or In-A+B) can be applied to any or all of DC-One’s six outputs. Choose a desired output channel from the output menu and press the Edit button to scroll to the Routing window using the Value up/down arrows.

Using the <SELECT> key to navigate to the Source parameter, apply a desired input selection to a selected output channel using the VALUE up/down keys to choose between inputs (In-A, In-B or In-A+B).

Cross-Over (Output Channels)

The DC-One’s crossover is an advanced frequency division process that is accomplished by applying a variety of high-pass and low-pass filters to a predetermined set of crossover points.

Speaker systems are generally made up of several drivers that are dedicated to a specific range of frequencies that result in the efficient reproduction of the audio spectrum and a smooth sound. The DC-One crossover routes frequencies to the appropriate drivers to accurately reproduce sound. The crossover network can also be used to insure that low-frequency energy is not accidently routed to the mid-range or tweeter drivers that may result in potential damage.

For detailed EQ plot images please see page 45

Available DC-One crossover parameters are Type and Frequency.

To access the Crossover screen,

filter. Different slopes and filter responses (6dB, 12dB with different Q values, Bessel, Butterworth, Linkwitz-Riley) are available and the filter can be bypassed. Again, the Hi-Pass frequency parameters are linked to the corresponding LoPass frequency parameter depending on the Configuration that is currently being used. High pass frequencies are set with a pre-determined frequency that attenuates frequencies below (the crossover point). On the contrary, a Low Pass filter passes frequencies below the crossover point and attenuates those above.

Crossover Alignment Delay

Use the <SELECT> button to navigate between the Crossover parameters. Adjust the values of each parameter using the up/down VALUE arrows.

Delay - Use this parameter to compensate for physical offsets of the acoustic centers of transducers within a loudspeaker cabinet. For example, due to cabinet construction, the acoustic center of a high frequency transducer may be mounted behind or in front of the acoustic center of the low frequency transducer. The Delay parameter can align the audio signal between the multiple transducers within the loudspeaker.

Delay (Output Channels)

DC-One’s output delays can be applied to output channels OUT1 - OUT6 and can be used to compensate for the positioning of cabinets or speaker arrays relative to each other or the original sound source.

The Delay parameter determines the delay time of the corresponding channel or the distance between different loudspeaker clusters. The delay time or physical distance is displayed in milliseconds, microseconds, feet, inches, meters, or centimeters.

To access the Delay screen, press the Delay button found on the output processing menu. Subsequent button presses will toggle the display between OUT1 to OUT6. Use the <SELECT> key to navigate between Delay (-200.00ms to

(50.0ms to

Limiter threshold values are determined by the amplifiers and loudspeakers that are used in the system. One important consideration in setting the limiter threshold value is the input sensitivity and gain of the connected amplifiers. Because different amplifiers can have different sensitivities, it is common to need to calculate the limiter offset to a factory preset based on the amplifier sensitivity. The DC-One offers a unique solution to this problem with the Amp parameter. All EV Factory Presets include limiter threshold values. You may use the Amp parameter to select the model of EV amplifier that you are using and the limiter threshold offset will be automatically calculated based on the amplifier gain and sensitivity. When an amplifier is selected from the list, the actual Threshold parameter will be locked to ensure that proper settings are maintained. It is very important to ensure that the proper amplifier is selected from the list, as an improper selection can result in incorrect Limiter settings for your system and may result in system damage. If a nonEV amplifier is used in the system, selecting “Other” from the amp list will allow the Threshold setting to be directly edited, however, the amplifier documentation should be consulted so you can calculate you limiter offset (if any) as needed. The Amp parameter is only available when using a Factory Preset.

Note: Sound travels at different speeds depending on the density of the surrounding air it is traveling through. Cold air is denser than warm air thus, travels slower than it would if the air was warmer. Temperature can have a major influence with greater distances, particularly with respect to widely separated speaker arrays surrounding the audience for example. Temperatures might vary wildly between an indoor environment and an outdoor evening environment for example.

V = 331m/s + (0.6m/s/C) * T

The speed of sound at room temperature is 346 meters per second. At freezing temperatures sound travels at 331 meters per second. V is the speed of sound and T is the temperature of the air. This formula finds the average speed of sound for any given temperature (celcius). The speed of sound is also affected by other factors such as humidity and air pressure.

This chart describes the channel assignments and linking schemes of the different configurations available in the DC-One.

Channels and parameters indicated with the same colors are linked. When making a change to one channel or parameter this will also affect the linked parameter or channel.

A dashed box around a Lo-pass/Hi-pass filter combination in adjacent channels indicates that these filters are linked. Changing the filter type and frequency of the Lo-pass filter will automatically change the linked Hi-

pass filter on the adjacent channel and vice versa.

These links are only enforced while in Standard Edit Mode. When entering Full Edit Mode, all channel and parameter links are removed.
