SRM-Flex Connect

Introduction

Do you want to control SRM-Flex via your Android or iOS device? Of course you do! Well, you’ve come to the right place! Afer all, the SRM-Flex Connect App is designed to be used in conjunction with SRM-Flex.

At this point, you must be well-versed in — or at least somewhat familiar with — the ins and outs of SRM-Flex. More information about SRM-Flex may be found by visiting the SRM-Flex Owner’s Manual.

You should be able to stream audio from any

Reference Guide

Bluetooth-paired device. However, the SRM-Flex Connect app is needed to mix audio, including wireless adjustments of level, EQ, reverb and more.

The SRM-Flex Connect app does not mix audio on its own. It requires an SRM-Flex to fully function.

SRM-Flex Connect is great for mobile freedom to control everything from levels and EQ to room-enhancing sound like reverb and speaker modes for amazing sound in any situation.

SRM-Flex Connect allows control of SRM-Flex via Bluetooth with the following devices:

SRM-Flex Connect V.0

This version of the Reference Guide is written and designed for SRM-Flex Connect V.0. With each sofware update, some screen shots may look slightly dierent than what you see within these pages and there could be some functional dierences, as well.

So there you have it. We hope you like it. If you have any questions or comments about this Reference Guide (or our other documentation), please don’t hesitate to contact us: www.mackie.com/support

About This Guide

The entire guide does not need to be read to ﬁgure out how to use the SRM-Flex Connect app. However, a certain amount of familiarity with the SRM-Flex and its features is assumed.

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.

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 SRM-Flex Connect app.

Things to Remember:

• Never listen to loud music for prolonged periods.

• Life is short. Be cool.

Getting Started

With SRM-Flex Connect, SRM-Flex users beneﬁt from the full power of their SRM-Flex with an easy-to-use application that ﬁts right in their hand.

* This is a list of our test devices, but a variety of other devices are anticipated to work with Android v6.0 and higher and Apple iOS .0 and higher.

There are a few steps to accomplish before messin’ around with the SRM-Flex Connect app. For starters, we’ll take a look at how to download, install and update the app. Next, we’ll pair the device with the hardware via Bluetooth. The last step is setting levels.

Additional Bluetooth Notes [Android and iOS]:

Part III: Level Setting Procedure

If the device had been previously connected to a SRM-Flex via Bluetooth, but it displays “Not Connected”, it’s quite possible that the SRM-Flex is not powered on.

The bluetooth level of most phones and tablets are directly linked with the level controls of the SRM-Flex. In other words, you may raise

SRM-Flex Connect

However, the bluetooth level of some older phones and tablets are not linked with the level controls of the SRM-Flex, but is rather a supplementary level control. In other words, the volume of the Bluetooth on the device needs to be up in order to hear audio over Bluetooth. If this does not make sense, please refer to Appendix C: Optimizations for step-by-step instructions.

or lower the volume with either the phone / tablet or SRM-Flex.

The Bluetooth may disconnect when aected by Electrostatic Discharge [ESD] or electrical fast transients (EFT). If this occurs, manually reconnect the Bluetooth connection.

The following steps will help you set up SRM-Flex quickly. Note that these same instructions may be found on page 4 of the SRM-Flex Owner’s Manuals, but are listed again below.

These startup instructions are intended for the hardware only. Once proven that the SRM-Flex performs as desired, then pair it with a device and control it via the SRM-Flex Connect app.

. Make all initial connections with the power switch OFF.

2. Connect height extension module(s) and/or HF driver

column to the base station.

3. Plug signal sources into SRM-Flex, such as:

• Microphones plugged into the mic inputs.

• Instrument level sources, such as acoustic guitars

w/active pickups into the instrument inputs.

• Line-level sources such as keyboards, drum machines,

or MP3 players plugged into the line-level inputs.

4. Push the line cord securely into the IEC connector

and plug the other end into a grounded AC outlet.

5. Turn the SRM-Flex on.

6. Pair and connect a phone or tablet via Bluetooth.

7. Be sure that the volume of the input is the same as it

would be during normal use.

8. Slowly bring up the main output level to a comfortable

listening level.

9. Read the rest of the SRM-Flex Owner’s Manual and the

SRM-Flex Connect app Reference Guide for more details!

SRM-Flex Connect

Welcome

The welcome screen is the ﬁrst thing you will see afer tapping the SRM-Flex Connect app. Here you are able to demo or start using the app.

If an Android or iOS device and SRM-Flex have been paired previously, the SRM-Flex Connect app will automatically load.

However, if SRM-Flex Connect IS NOT connected to an SRM-Flex via Bluetooth simply tap ‘Demo’ to demo the app.

SRM-Flex Connect – Three Main Views

From here on out, operation is virtually identical between Android and iOS. In addition to the opening Welcome view, there are three main views in the SRM-Flex Connect app and this page outlines what may be accomplished with each of these three views. Soon enough we will go through each of these in detail.

Mixer View

If the ﬁrmware version in the SRM-Flex is older than the SRM-Flex Connect app, you will be prompted to update the ﬁrmware. The latest ﬁrmware is built into the SRM-Flex Connect app, so there is nothing additional to download. Just follow the on-screen prompts.

System View

As seen in the image above, the System View allows access to deeper functionality including Settings, Memory and more. From here you’re able to one-touch navigate back to the Mixer View.

Reference Guide

Mixer View

Introduction

As mentioned earlier, the Mixer View allows access to key controls such as levels, metering, mutes and more.

1. Mute

Mute buttons do just what they sound like they do.

SRM-Flex Connect

They mute — turn o — the signal on the channel(s).

Mute buttons illuminate red when engaged and are gray when disengaged.

2. Channel Name

The input and output channels are labeled between the mute buttons and faders and meters. These labels display the fader value as the fader level is adjusted; in the case to the right, –4.2 dB on the BT channel.

That’s not all! If you press and hold a ﬁnger over the channel name, the keyboard appears. Here you’re able to rename all inputs and outputs. Simply type in the name you want for that input / output followed by tapping the ‘Done’ button.

Are emojis more your thing? Use those instead of text! Check out channels 3-4 (keyboard) and the Bluetooth channel (phone containing backing tracks).

Input Channels 1–2

3–4

BT / 5–6

Main Mix

3. Channel Faders and Input Meters

The touch sensitive faders adjust the channel’s relative volume to the master bus. Adjustments are made by touching and dragging channel faders up and down.

The input meters display the input signal level to the channel before all channel processing.

• Channels -4: –

• Bluetooth Channel: – dB (o) to +0.0 dB (max)

dB (o) to +6.0 dB (max)

You may notice some latency with the metering. This is due to the limitations of Bluetooth, not the SRM-Flex.

4. EQ Channel View

The buttons located at the bottom of channels  and 2 allow access to the selected channel’s Channel View.

When tapped, the entire selected channel strip slides to the lef and the main mix strip remains on the right. The middle then becomes occupied with the selected channel’s EQ section. See the following page.

The sliders on the EQ button lie horizontally in mixer view and vertically in channel view. Simply tapping this button again returns you to the mixer view.

Nav to Mixer ViewNav to Channel View

SRM-Flex Connect

5. Main Mix

The main mix strip looks and works nearly identical to that of an input channel strip. The only dierences are: () this fader adjusts the main output level of the SRM-Flex and (2) instead of an EQ button at the bottom of the strip, there is a gear icon button. This takes you to the system view and it is detailed below.

Reference Guide

7. Low EQ

This ball gives you up to 5 dB boost / –5 dB cut below 80 Hz. The processing is ﬂat (no boost or cut) at the center position. This frequency represents the punch in bass drums, bass guitar, fat synth patches, and some really serious male singers (as opposed to really funny male singers). Double-tap the EQ ball to reset it to ±0 dB.

6. System View Button

The gear icon button located at the bottom of

the main mix strip allows access to the System View.

When tapped, all channel strips disappear and the main mix strip remains on the right. The rest of the screen then becomes occupied with the System View settings.

As seen below, the button in mixer view [gear icon] and channel view [vertical sliders] diers. Simply tapping this button again returns you to the Mixer View.

Nav to Mixer ViewNav to System View

Channel View

Main MixInput Channel EQ and Reverb Send

8. High EQ

This ball gives you up to 5 dB boost / –5 dB cut at

6.0 kHz, and it is also ﬂat at center. Use it to add sizzle to cymbals, and an overall sense of transparency, or edge to keyboards, vocals, guitar and bacon frying. Turn it down a little to reduce sibilance, or to hide hiss. Double-tap the EQ ball to reset it to ±0 dB.

Introduction

As mentioned earlier, the Channel View allows access to the channel EQ and reverb level controls. From here you’re able to one-touch navigate to the Mixer View and System View.

2-Band EQ

SRM-Flex Connect has 2-band equalization at carefully selected points — low shelving at 80 Hz and high shelving at 6.0 kHz. “Shelving” means that the circuitry boosts or cuts all frequencies past the speciﬁed frequency. For example, dragging the low EQ ball 5 dB to the top boosts bass starting at 80 Hz and continuing down to the lowest note you never heard and 6.0 kHz on up boosts the treble in the case of the high EQ.

With too much EQ, you can screw things up royally. We’ve designed a lot of boost and cut into the equalizer circuit because

we know everyone will occasionally need that. But if you max the EQs, you’ll likely get mix mush. Equalize subtly and use the bottom side of the EQ balls (cut), as well as the top (boost).

9. Reverb Send

This slider allows you to select the amount of reverb

you would like to add per channel from o (far lef,

0.0%) to max (far right, 00.0%). Reverb is available on input channels

 and 2, but not the other channels.

Don’t hear any reverb? Make sure it’s turned on either via the SRM-Flex or SRM-Flex Connect app.

Reference Guide

System View

Introduction

As mentioned earlier, the System View allows access to deeper functionality including Settings, Memory, access to the About view and more.

0  2

SRM-Flex Connect

As seen in the screen shot above, there are three system menu buttons from which to choose. The currently selected tab will illuminate white and is underlined green.

Speech EQ Mode – This mode features a signiﬁcant low frequency roll-o to get rid of unwanted thumps. It also adds boost and sparkle to mid-range and high frequencies, critical for speech applications.

This plug-and-play mode is perfect for applications where speech is the primary audio source in need of clear and precise intelligibility.

Live EQ Mode – This mode is ﬂat, perfect for singer-songwriters and other live performers.

RVB Mode – Are you interested in adding some reverb to the signal? It can’t be more straighforward. Simply tap “” (small room), “2” (medium room) or “3” (large room) to turn it on and “O” [Default] to turn it o. The border of the selected mode will illuminate green, as well as the text to conﬁrm the reverb mode status.

Setting reverb levels was discussed on the previous page, call-out number nine.

• Settings

• Memory

• About From here you’re able to one-touch navigate back

to the Mixer View with a simple, single tap of the Mixer View button.

Nav to Mixer View

10. Settings

The settings tab is where to select an EQ mode,

reverb mode, make LED selections and more.

EQ Mode – This allows you to change the SRM-Flex’s

mode to tailor it to best suit your particular application. Simply press the text of the speaker mode you want. The border of the selected mode will illuminate green, as well as the text.

The three speaker modes are as follows:

LED Bar Mode – In addition to meter displays on SRM-Flex Connect, main meters are also displayed on the LED bar located on the top panel of SRM-Flex.

The two LED bar modes are as follows:

Meter [Default] – Meter – aka peak meter mode – displays bouncing meters.

Volume – Volume mode, on the other hand, is a solid bar, no bouncing meters. This updates as the level is (manually) changed.

The LED Bar Mode choices listed above only apply to SRM-Flex. The SRM-Flex Connect meters will always be bouncing happily (even when the LED Bar Mode is set to

‘Volume’).

Front LED Mode – There are two horizontal LED bars on the front of SRM-Flex. One bar is located near the bottom of the base station / subwoofer and the other near the top of the high frequency driver column.

Music EQ Mode [Default] – This mode is full range,

but focuses on increased bass and brilliant high frequencies. This is the place to start for most DJ / music playback applications.

SRM-Flex Connect

The three front LED modes are as follows:

On [Default] – The LEDS illuminate in all their glory.

Signal – The LEDS illuminate when there is signal

at the outputs.

O – The LEDS do not illuminate; they are turned o and SRM-Flex is in ‘stealth’ mode.

System View Continued...

Reference Guide

Auto Connect – When ON [Default] is selected, this allows a previously paired device to auto reconnect if both the device and SRM-Flex are powered on and in range.

As such, when OFF is selected, a previously paired device will not reconnect automatically regardless of the range or on/o status of the device and SRM-Flex. The border of the selection will illuminate green, as well as the text to conﬁrm your choice.

The Bluetooth connection may disconnect when aected by electrostatic discharge (ESD) or electrical fast transients (EFT). If this occurs, manually reconnect the

Bluetooth connection.

11. Memory

When the memory tab is selected, settings for SRM-Flex may be saved to memory and recalled at a later time. What’s more, each setting may be custom-named! No more having to reset levels upon every power-up or trying to remember what each snapshot represents.

Rename – Tap this to bring up the blinking cursor and keyboard. Simply type in the name you want for that snapshot followed by tapping the ‘Done’ button.

This is what you will see when the ‘Memory’ tab

is tapped for the ﬁrst time:

There are a whopping 0 user snapshots and another

to recall the default settings.

Lef to right are save, recall and rename: Save – Tap this to save the current settings

to the corresponding snapshot.

Please be aware that the new settings will replace the currently saved settings.

Recall Default Snapshot – Tap this to return all settings — faders, mutes, EQ, etc. — to their default settings. It is a convenient way to start with a fresh slate, essentially “zeroing out” the board.

This selection will always remain at the top, above all the user snapshots.

12. About

Once tapped, the ‘About’ tab displays information about the SRM-Flex Connect app version that is currently installed on the device.

Recall – Tap this to recall the settings of the selected

snapshot.

Troubleshooting

If you think your SRM-Flex 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) where you will ﬁnd lots of useful information such as FAQs and other documentation. You may ﬁnd the answer to the problem without having to part with your SRM-Flex.

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):

() — Restart the device. Don’t just restart the SRM-Flex Connect app. Restart the device! Completely power it down, then power it back up.

(2) — Restart the SRM-Flex. This is especially useful afer sofware updates where the hardware and sofware aren’t quite on the same page. A simple reboot of the hardware can sometimes work great wonders.

Poor sound

• Is it loud and distorted? Make sure that you’re not overdriving a stage in the signal chain. Verify that all level controls are set properly.

• Is the input connector plugged completely into the jack? Be sure all connections are secure.

Noise

• Make sure all connections to the SRM-Flex are good and sound.

• Make sure none of the cables are routed near AC cables, power transformers, or other EMI-inducing devices.

• Is there a light dimmer or other SCR-based device on the same AC circuit as the SRM-Flex? Use an AC line ﬁlter or plug the SRM-Flex into a dierent AC circuit.

(3) — Level setting procedure. If you are having any sound (or non-sound) issues, try following the level setting procedure as outlined on page 8 to verify that all of the volume controls in the system are properly adjusted.

No power

• Our favorite question: Is it plugged in? Make sure

the AC outlet is live [check with a tester or lamp].

• Our next favorite question: Is the power on?

If not, try turning it on.

No sound

• Is the level of the input source turned all the way down? Verify that all the volume controls in the system are properly adjusted.

• Is the signal source working? Make sure the connecting cables are in good repair and securely connected at both ends. Make sure the output level control of the source is turned up suciently.

• Make sure the source(s) are not turned o or muted. If you ﬁnd something like this, make sure the level is turned down before disengaging the oending switch.

Hum

• Try disconnecting the cable(s) connected to the main input jack(s). If the noise disappears, it could be a “ground loop,” rather than a problem with the SRM-Flex. Try some of the following troubleshooting ideas:

• Use balanced connections throughout your system for the best noise rejection.

• Whenever possible, plug all the audio equipment’s line cords into outlets which share a common ground. The distance between the outlets and the common ground should be as short as possible.

Bluetooth / Other Issues

• Are you running the latest and greatest SRM-Flex Connect sofware? Go to the Play Store [Android] or App Store [iOS] and check for an update.

• Leave SRM-Flex Connect and then return by pressing the Home button on the device.

Appendix C: Android and iOS Optimizations

Android Optimizations

Below is a list of ways to trick out your Android device to optimize its use with the SRM-Flex Connect app. When you have some additional time, use your favorite search engine to search “trick out your Android device” for other ways to optimize your Android device. All of the following tips and tricks may be found by going to Settings on the Android device.

Android Optimization # : Mute sounds, including phone calls, email alerts, calendar event warnings, alarms and other extraneous Android noises (except music apps; those will continue to play).

If a mic is plugged into an SRM-Flex, the person on the other end of a call can’t hear you, so they’re better o leaving a voice mail, anyway.

First, go to Sound and tap ‘Do Not Disturb’.

Reference Guide

Next, tap ‘Turn on now’. The previous screen will show that ‘Do Not Disturb’ is now ON.

Android Optimization #2 : The bluetooth level of most phones and tablets are directly linked with the level controls of the SRM-Flex. In other words, you may raise or lower the volume with either the phone / tablet or SRM-Flex.

Simply go to Sound and drag the ‘Media volume’ slider to the right.

Note that the call volume, ring volume and alarm volumes are all o [sliders fully lef].

Android Optimization #3 : SRM-Flex Connect and Auto Updating Apps

Android allows apps to be updated in the background. This is great for consumer apps like games, etc. However, you use apps like SRM-Flex Connect and auto-updating your apps can cause problems if the process is not properly understood. Before you update that app, let’s ﬁrst understand how updates generally work.

. You are notiﬁed of a SRM-Flex Connect update through the Play Store.

2. You download and install the update. Boom. The app is updated.

But now, the operating system can update an app in the background automatically, including the SRM-Flex Connect App. While highly unlikely, it is possible that this could cause serious problems during a presentation or performance. Obviously this is not something you want to happen. To avoid this, we strongly recommend you disable automatic updates for Apps.

Here’s how:

Tap the Play Store icon to open it.

In the upper-lef corner are three horizontal lines, sometimes referred to as a ‘hamburger’. Tap it.

Reference Guide

From here you will want to tap ‘Settings’ followed by ‘Auto-update apps’.

Lastly, simply select “Do not auto-update apps.” It will be noted in your settings!

Reference Guide

Android Optimization #4 : Blocking calls.

To block calls, go to Settings > Network & internet and put the phone into ‘Airplane Mode’.

Then go to Settings > Connected devices and turn Bluetooth back on.

SRM-Flex Connect

iOS Optimizations

Below is a list of ways to trick out your iOS device to optimize its use with the SRM-Flex Connect app. When you have some additional time, use your favorite search engine to search “trick out your iOS device” for other ways to optimize your iOS device. Most of the following tips and tricks may be found by going to Settings > General on the iOS device.

iOS Optimization # : Prevent the device from turning o in the middle of a presentation (or worse yet, a rockin’ karaoke performance!).

Simply change the Auto-Lock from its current selection to “Never”.

Reference Guide

SRM-Flex Connect

iOS Optimization #2 : Turn o Lock Sounds and Keyboard Clicks.

iOS Optimization #3 : Mute sounds, including email alerts, calendar event warnings, alarms and other extraneous iOS noises (except music apps; those will continue to play).

Use Side Switch to: Mute

Flip the side switch on the device (next to the volume up/down switch) so that the orange dot is visible. It indicates that the device is indeed muted (except for the music apps).

. You are notiﬁed of a SRM-Flex Connect update through the iOS App Store.
