Frequently Asked Questions - PROMIX22U VELLEMAN

How to connect a microphone to the mixing console?

Use an XLR input on the mono channels. Plug the microphone into the MIC input. Adjust the gain with the TRIM potentiometer for an optimal level.

Can I use instruments like a guitar directly on the line input?

Yes, the LINE input accepts unbalanced signals. Use a mono 1/4" jack cable. The gain is sufficient for weak signals.

How to adjust the equalizer on the mono channels?

Turn the HIGH (12 kHz), MID (2.5 kHz), and LOW (80 Hz) potentiometers to boost or cut up to 15 dB. The center click corresponds to the neutral position (0 dB).

What does the PEAK LED on a channel mean?

The PEAK LED lights up when the signal approaches saturation (3 dB before). If it stays lit, reduce the TRIM gain to avoid distortion.

How to connect the mixing console to a computer?

Use the USB port on the rear. Connect a USB cable to your computer. The signal is routed to channels 4/5/USB. Make sure the volume of these channels is turned down before connecting/disconnecting the USB cable.

What type of power adapter to use?

Use exclusively the supplied power adapter (18 VDC / 300 mA). Plug it into the socket on the rear of the mixing console.

Can I record the mix on a tape recorder?

Yes, use the REC OUT (RCA) outputs to connect a recording device. The signal comes from the MASTER MIX.

How to monitor the sound with headphones?

Plug your headphones into the PHONES output (TRS 1/4"). Adjust the volume with the PHONES potentiometer. The signal comes from the MASTER MIX.

What to do if the mixing console does not power on?

Check that the power adapter is properly plugged in and that the wall outlet works. Make sure the POWER switch is set to ON. If the problem persists, contact your dealer.

How to clean the mixing console?

Disconnect the device before cleaning. Use a soft, dry cloth. Do not use chemicals or water. Avoid moisture.

3. Description

a. Mono Input

1. MIC Input

Each mono input channel offers a balanced microphone input via the XLR connector. The XLR jack is configured for pin 1 (ground), pin 2 (positive (+)) and pin 3 (negative (-)).

2. LINE Input

The LINE input is designed to accept balanced or unbalanced line level signals such as those from keyboards, drum machines or samplers. There is enough gain available on the line input to accept even lower level signals such as those from an unbalanced microphone or guitar output. If a balanced signal is to be connected to the line input, then a 14 " TRS (stereo) phone plug should be wired for the tip (positive (+)), the ring (negative (-)) and the sleeve (ground).

MC LINE 1 1 2 BAL OR UNBAL

NOTE: Either the MIC or the LINE input of a given channel can be connected at one time. Never connect both simultaneously to the same channel.

3. TRIM

The TRIM control adjusts the input sensitivity (channel gain) of the MIC and LINE inputs on the mono input channels. This control can be adjusted to accommodate input signals from a wide variety of sources, from the high outputs from keyboards or drum machines to the small signal outputs of microphones. This wide range eliminates the need for MIC / LINE switching. The best S/N balance and dynamic range will be achieved if you adjust the TRIM control on each channel separately so that the PEAK LED (6) for that channel lights occasionally.

NOTE: This control should always be turned fully anticlockwise whenever you connect or disconnect a signal source to one of the inputs.

4. EQUALIZER

All mono input channels are fitted with three-band EQ. The upper (HIGH) and lower (LOW) shelving controls have their frequencies fixed at 12kHz and 80Hz respectively. The midrange control has a peaking response, with Q fixed at 2 octaves and the frequency at 2.5kHz. All three bands have up to 15dB of cut and boost with a centre detent for "off".

5. PAN Control

The channel PAN positions the output of the channel in the stereo field of the Master Mix. Its constant-power design ensures there are no level discrepancies whether a signal is hard-panned, centre-stage or somewhere in-between.

6. PEAK LED

The PEAK LED illuminates when a channel is going into overload. It detects the peak level after the EQ and will light at 3dB before clipping to warn that the signal is approaching overload. You do not want the PEAK LED to light except very intermittently during a take or a mix. If it does light persistently, reduce input gain with the TRIM control (3).

7. Channel LEVEL Controls

The channel LEVEL controls determine the output signal level to the MASTER MIX bus. There is no PFL function on the mixer. In order to audition any single channel for proper gain, you can turn off the gain control of all the other channels (fully anticlockwise) and set both the auditioned channel and MASTER MIX control (16) to unity gain (0dB). The LED OUTPUT meter (15) should read around 0dB.

b. Stereo Input

7. Channel LEVEL Controls

The channel LEVEL controls determine the output signal level to the MASTER MIX bus. There is no PFL function on the mixer. In order to audition any single channel for proper gain, you can turn off the gain control of all the other channels (fully anticlockwise) and set both the auditioned channel and MASTER MIX control (16) to unity gain (0dB). The LED OUTPUT meter (15) should read around 0dB.

8. LINE Input

Each stereo channel has two balanced line level inputs on 14 " TRS jacks for left and right channels (tip = positive (+), ring = negative (-), sleeve = ground). If only the connector marked "L" (left) is used, the channel operates in mono. The stereo channels are designed to handle typical line level signals. The input signals to these jacks can be either balanced or unbalanced.

LINE 2/3 L MONO R LINE 4/5 L MD NO R 8 8

1. BAL Control

For a mono input to the L (MONO) input the function of the control is the same as the PAN controls (5) of the mono channels. However, when a channel is run in stereo, this control functions as a BALANCE control, determining the relative balance of the left and right channel signals being sent to the left and right MASTER MIX buses. For example, with the BALANCE control turned fully clockwise, only the right portion of the channel's stereo signal will be routed to the MASTER MIX.

c. Master

1. STEREO Output

Use these jacks to connect to an external power amplifier if extra output power for a larger PA system is required. The stereo outputs are left (L) and right (R) unbalanced 14 " TRS jacks, wired as tip = positive (+), sleeve = ground.

1. PHONES Output

The PHONES output will feed headphones and is a 14 " TRS jack, wired as tip = left signal, ring = right signal, sleeve = ground.

1. TAPE Input

These jacks will accept the signal from an external device with a stereo output such as a cassette recorder.

1. REC Output

The REC outputs also provide an output of the MASTER MIX. These outputs are RCA jacks and designed primarily for inputs to tape recorders etc.

1. POWER ON LED

The red LED indicates that the console is powered on.

1. VU METER

The 4-stage LED VU meter displays the MASTER MIX output level.

1. MASTER MIX GAIN Control

The output level routed to the STEREO outputs and REC outputs is determined by the MASTER MIX GAIN control.

1. TAPE/REC to PHONES Switch

Use the TAPE / ECHO TO PHONES switch to route signals from the TAPE input (12) to the PHONES control (19).

1. TAPE/REC to MASTER Switch

Use the TAPE / ECHO TO MASTER switch to route signals from the TAPE input (12) to the MASTER MIX GAIN control (16).

1. PHONES Control

The mixer allows you to monitor the MASTER MIX. The signal level is adjusted with the PHONES control and routed to the PHONES (11) output.

d. Rear Panel

1. MAIN POWER Switch

This switches the mixer ON or OFF.

NOTE: Be sure to switch on the power to your mixer before switching on the amplification system.

1. AC POWER Input

Connect the enclosed power supply to the 3-pin mains connector on the rear of the console. Use the included adapter to connect the console to the mains.

22. USB Connection

The USB connection can be used for playing MP3 or other audio files from a computer or for recording your performance to a computer. The signal is sent to channels 4/5/USB.

NOTE: Be sure to turn channels 4/5/USB all the way down before connecting/disconnecting the USB cable.

4. Connections

Unbalanced equipment may be connected to balanced inputs/outputs. Either use mono 14 " jacks or connect the ring and sleeve of TRS jacks. Never use unbalanced XLR connectors on the MIC input connectors when using a phantom power supply.
