PROEL MQ Series Overview Video

This video provides an overview of the PROEL MQ Series compact mixers. Please note that some features shown, such as digital effects, compressors, and USB connectivity, are available on other models within the MQ series (e.g., MQ6FX, MQ12USB, MQ16USB) and not on the MQ6 model specifically.

4. Setup

4.1 Unpacking and Inspection

Carefully unpack the mixer and check for any signs of damage. Ensure all components listed in the packaging are present. If any items are missing or damaged, contact your dealer immediately.

4.2 Power Connection

Ensure the mixer's power switch is in the OFF position.
Connect the provided power adapter to the DC input jack on the rear of the mixer.
Plug the power adapter into a suitable AC power outlet.

4.3 Input Connections

The MQ6 features two types of input channels:

Mono MIC/LINE Inputs (Channels 1-2): Use XLR cables for microphones or 1/4" TRS cables for line-level instruments (e.g., keyboards, guitars with preamps).
Stereo LINE Inputs (Channels 3/4, 5/6): Use 1/4" TRS cables for stereo line-level sources. If connecting a mono source, use the L/MONO input.

4.4 Output Connections

MAIN MIX Outputs: Connect your main speakers or power amplifier to the XLR MAIN MIX L and R outputs. These outputs are electronically balanced.
PHONES Output: Connect your headphones to the 1/4" PHONES jack for monitoring.

5. Operating Instructions

5.1 Powering On/Off

Before powering on, ensure all channel GAIN and MIX level knobs are set to their minimum position.
Turn on the mixer using the power switch on the rear panel.
When powering off, first turn down all output levels, then switch off the mixer.

5.2 Channel Controls (Mono Channels 1-2)

MIC/LINE Input: Combo jack for XLR microphones or 1/4" TRS line-level sources.
LO CUT (75 Hz): Engages a high-pass filter at 75 Hz to remove unwanted low-frequency rumble.
GAIN: Adjusts the input sensitivity for the connected microphone or line source. Set this to achieve a strong signal without clipping (indicated by the PEAK LED).
HI (12 kHz): Adjusts the high-frequency (treble) content of the channel.
LOW (80 Hz): Adjusts the low-frequency (bass) content of the channel.
PEAK LED: Illuminates when the input signal is too high, indicating potential clipping. Reduce the GAIN if this LED lights up frequently.
Level Knob: Controls the channel's contribution to the main mix.

5.3 Channel Controls (Stereo Channels 3/4, 5/6)

L/MONO, R LINE Inputs: 1/4" TRS jacks for stereo line-level sources. Use L/MONO for mono sources.
HI (12 kHz): Adjusts the high-frequency (treble) content of the channel.
LOW (80 Hz): Adjusts the low-frequency (bass) content of the channel.
Level Knob: Controls the channel's contribution to the main mix.

5.4 Main Mix Section

PHANTOM POWER ON/OFF: Activates +48V phantom power for condenser microphones connected to the XLR inputs. Ensure condenser microphones are connected before activating phantom power.
Level Meters: Displays the output level of the main mix. Aim for levels around 0 dB to avoid clipping.
MIX Level Knob: Controls the overall output volume of the main mix.
PHONES Level Knob: Adjusts the volume for the headphone output.

6. Maintenance

Cleaning: Use a soft, dry cloth to clean the mixer's surface. Do not use abrasive cleaners, solvents, or waxes.
Storage: When not in use for extended periods, store the mixer in a dry, dust-free environment.
Cable Care: Regularly inspect all cables for damage. Replace frayed or damaged cables to prevent electrical hazards and ensure optimal performance.
Ventilation: Ensure the ventilation slots are clear of dust and debris to prevent overheating.

7. Troubleshooting

Problem	Possible Cause	Solution
No sound output	Mixer not powered on. Main MIX level too low. Channel level too low. Incorrect cable connections. Speakers/amplifier off or muted.	Check power switch and adapter. Increase MAIN MIX level. Increase individual channel level. Verify all audio cables are correctly connected. Ensure speakers/amplifier are on and not muted.
Distorted sound	Input GAIN too high. Output level too high. Damaged cables or equipment.	Reduce channel GAIN until PEAK LED no longer illuminates. Reduce MAIN MIX level. Check and replace faulty cables or equipment.
No microphone signal	GAIN too low. Phantom power off (for condenser mics). Faulty microphone or cable.	Increase channel GAIN. Activate PHANTOM POWER if using a condenser microphone. Test with a different microphone or cable.
Hum or noise	Ground loop. Unshielded cables. Interference from other electronics.	Ensure all equipment is on the same power circuit or use a ground loop isolator. Use high-quality shielded cables. Move mixer away from power supplies or other noisy electronic devices.
