Frequently Asked Questions - CM10-LIVE Citronic

How do I connect the mixer to an amplifier?

Use quality 6.3mm jack leads (balanced or unbalanced) to connect L+R outputs from the mixer to the amplifier. Ensure all volume controls are turned down before connecting, and switch the amplifier on last.

How do I use phantom power?

Press the '+48V' switch on the control panel to activate phantom power. This is required for condenser microphones and is available on XLR inputs. Ensure microphones are connected before switching on.

How do I adjust the internal delay effect?

For LIVE models, use the DELAY control to adjust time between repeats and the REPEAT control for number of repeats. The EFFECT control adjusts overall effect level. Each channel has an EFF knob to feed signal to the delay.

Can I connect external effects?

Yes, plug a jack lead into the EFFECT output to defeat the internal delay. This acts as a mono send to an external effect unit. Return the processed signal via a mono or stereo channel using the channel fader for overall level.

How do I play music from a USB drive or SD card?

Insert a USB pen drive or SD card (with compressed audio files) into the rear panel slots. The player auto-starts playback through the stereo channel. Use transport controls (Play/Pause, skip) on the control panel.

What should I do if there is no power?

Check that the power adapter is connected properly and the mains outlet voltage matches. Ensure the power adapter is working. The power LED should illuminate. If not, try a different outlet.

How do I set the gain level for a channel?

Make the loudest expected sound into the microphone or instrument. Gradually increase the GAIN control until the red PEAK LED starts to light, then back off slightly so the LED hardly lights.

Why is there no sound from the speakers?

Check that all faders (channel and MAIN) are not fully down. Verify input connections and that the GAIN is not too low. Also check amplifier/recorder levels and that speakers are connected properly.

How do I use the AUX output?

Each channel has an AUX control that sends a pre-fader signal to the AUX output. Adjust the AUX output level with the master AUX control. This is useful for monitor mixes or external processing.

What is the difference between LIVE and STUDIO models?

LIVE models (e.g., CM10-LIVE) include a USB/SD media player and internal delay effect. STUDIO models (e.g., CM8-STUDIO) have USB audio input/output for computer recording instead of the media player.

Connection

Before connecting to amplifier or other equipment, turn down all volume controls to avoid loud noises which may cause damage to other equipment. Always switch amplifier power on last in line with volume levels down.

Using good quality 6.3mm jack leads (balanced or unbalanced), connect L + R outputs from the mixer to the amplifier, recorder or whichever equipment is to receive the main mix output.

If phantom power is to be used, press the "+48V" switch in.

Connect microphones, DI boxes and other balanced low impedance audio inputs to the mono channels using a quality XLR lead.

Connect high impedance and line level signals to the mono inputs using a 6.3mm jack lead.

For the stereo channel, connect left and right line level signals via 6.3mm jack or RCA leads (unbalanced).

Channel inserts may be connected to individual processing equipment like EQ or compressors. These connections completely interrupt the signal flow and divert to the external processor before returning to the channel for volume adjustment via the channel fader. This requires a stereo to 2 x mono jack lead – the 2 mono ends are send and return connections, the stereo connection is wired as per below.

Recording equipment can be connected via the "REC" outputs using a twin RCA lead and the 6.3mm jack AUX output can be connected to monitoring or external processing equipment if required. Individual levels can be adjusted to the AUX output via the individual channel AUX controls.

For CM-LIVE models, if the internal delay effect is not required, a send can be connected from the "EFFECT" jack output to and external effect unit, whereby the EFF channel controls act as individual level controls to the EFFECT output (same as for AUX output)

With all faders down, connect the supplied AC adapter to the 12Vac input and to the mains supply (ensure correct supply voltage) – the power LED will illuminate (if phantom power is selected, this LED should light also)

Checking

Test each channel's gain level by making the loudest expected sound into it and increasing the GAIN control until the red PEAK LED starts to light. Then back the GAIN off slightly until the PEAK LED hardly lights at all.

Test the main mix output by increasing the MAIN fader and selected channel faders whilst making sound through the channel(s) - the L + R output LED ladders should begin to show the output as it varies up and down.

Connecting a pair of headphones to the PHONES stereo 6.3mm jack is a good way of checking the mix output, remembering to gradually increase the PHONES level control.

Turn down all faders and then switch power on to connected equipment (amplifier last in line) and increase volume levels. Gradually increase MAIN and channel faders again and the sound should be heard through the speakers or be indicated on the recording equipment.

Operation

Each channel has a 3-band EQ (LOW/MID/HIGH), which can be used to balance the mix of frequencies and emphasise certain aural characteristics in the signal. Adjust these as required, noting that and overall increase may require an equivalent reduction of the GAIN control to compensate (otherwise clipping may occur from EQ boost).

Use the PAN control to position the channel input either to the left or right side of the stereo field. This can be useful to help separate and define sounds within a mix but be aware that extreme settings can be counter-productive by removing the channel from certain listening positions.

Use the AUX control to feed the correct amount of the channel signal to the AUX output. This routing is “Pre-fader” and is independent from the channel fader setting.

For CM-LIVE models, there is an EFF control, which feeds a part of the signal to the internal delay effect. Overall controls for DELAY (time between repeats) and REPEAT (number of repeats) are on the right-hand side of the control surface - these can be adjusted as required. An EFFECT control adjusts the overall level of the delay effect.

If external effects are to be used, plugging a jack lead into the EFFECT output defeats the internal delay effect and acts as a mono line level "send" to the external effect unit. The output(s) from the external unit will need to be "returned" via a mono or stereo channel and added to the mix, whereby the channel fader takes the place of the overall EFFECT level control.

Channel faders should be used to adjust the individual levels in the mix and the MAIN fader is for overall level. Turn down amplifier levels when changing any connections or powering down the mixer to avoid speaker damage.

USB features

For the CM-LIVE models, The USB and SD card connection is for the internal media player, which can offer playback of compressed digital audio files through the stereo channel. When a USB pen drive or SD card with such files on is connected via the rear panel, the player recognises this and automatically begins playback through the stereo channel. The player status is indicated by a small backlit LCD screen, as shown below...

A. Indicates media type (music/audio)
B. Indicates Play status (Play / Pause)
C. File / Folder indication
D. Bit resolution of file
E. Media source (USB / SD card)
F. Elapsed / Total track time
G. Track name
H. Spectrum output display

Transport controls allow navigation through tracks on the memory device. These are outlined below...

For CM-STUDIO models, connecting a USB A to B lead from the rear panel USB connector to a USB port on a PC or Mac computer allows audio to be transferred between the mixer and computer. The PC or Mac will recognise the CM-STUDIO mixer as an external USB audio device and the mixer can be selected as an audio source within recording software and as an output to the mixer, received as a main mix return. The firmware offers plug-and-play compatibility with Windows XP/Vista/7 and OS/X onward.
