Lo: Controls the low frequency tone of each channel. Always set this control to the 12 o’clock position.
Aux: Allows access to a portion of each channel’s signal which provides a monitor mix that can be fed to stage moni-tors, independent of the main mix. The control is off when fully turned down, delivers unity gain at the 12 o’clock position, and can provide up to 15dB of gain when turned up fully.
FX: Allows access to a portion of each channel’s signal which provides an FX mix feeding the internal FX processor and external processors via the FX output. The control is off when fully turned down, delivers unity gain at the 12 o’clock position, and can provide up to 15dB of gain when turned up fully.
Pan: The Pan control sends continously variable amounts of the post fader signal to either the left or right main busses.In the center position equal amounts of signal are sent to either bus.
Mute: Pressing the Mute button will turn off the channel’s signal output.
OL (Peak Level Indicator): The red LED indicates the sig- nal level at the insert return point, premaster fader, and illumi-nates at 5dB below clipping.
Channel Fader: This slider adjust the level of each channel into the signal mix. The U mark indicates unity gain, meaning no increase or decrease of signal level.
Solo: This switch allows you to hear signals through your headphones or control room without having to route them to the main mix. Use solo to preview channels before they are fed into the mix. You can solo as many channels at a time as you like.

MASTER SECTION
Auxillary Return: This control sets the overall level of line signals received from the stereo (aux) return L/R jacks. Signals passing through this control goes directly to the main mix and monitor mix where they are combined with signals from the channels.
Auxillary Send: This control sets the overall level of the Aux send prior to it going into the external effects device
FX Send: This control determines how much of the effects processor’s signal should be added to the main mix.
Phones: This knob controls the levels of the headphones and the main monitors.

Digital Effects Processor: Features 16 effect presets with variable parameters. To select a specific effect, use the preset select knob. To control the parameters of that effect, use the knobs marked Param 1 and Param 2. To control how muchof the effect is applied to the main mix, use the FX send knob (see item 18). The chart below shows the effects and the adjustable parameters. This chart is also printed on the mixer for your convenience.

EQ Kill Switch: This button allows you to quickly engage or disengage the equalizer.
Limit Right/Limit Left: The yellow Limit LED of the correspodnig channel will shine dimly at the onset of clipping and increase in brilliance as the clipping be- comes more severe, staying on until the clipping ceases. If the LEDs are flashing quickly and intermittently, the channel is at the clip threshold. A steady bright glow means the amp is clip limiting or reducing gain to prevent severly clipped waveforms from reaching the speakers.
Phantom Power Switch: Depressing this switch applies 48V DC across all microphone input channel connectors for remote powering of condenser microphones. The LED will turn on once phantom power is engaged.
Output Level Indicator: This peak level meter is made up of 10 LEDs with 3 colors to indicate the different ranges of signal level. The meters will show OdB when there is OdBu (.775V) present at the main left and right TRS outputs. When soloing a channel, the left meter shows the specific channel’s signal level (pre-fader). The OdB LED indicates where the level should be when adjusting the channels gain. During solo operation the right meter will remain inactive.
Power Indicator LED: Indicates when the unit is on.
Solo Indicator LED: This LED flashes red when one or more solo switches are engaged. This will remind you that what you are hearing in your headphones or control room is the soloed channel(s).

MASTER SECTION
FX Level: This slider is used to adjust the signal level of echo, repeat, and exterior effects.

CONNECTIONS

Balanced vs. Unbalanced Lines

A balanced line is a three-conductor system in which two signal wires carry an equal, but opposite voltage with respect to the ground wire. The ground wire acts only as a shield and does not carry any audio signal current. Outside interference is either shielded from the internal signal conductor, or if it gets into the cable is cancelled out by the opposite signals at the receiving end. Balanced connections are preferred for long cable runs.

An unbalanced cable is a two-wire system where the shield (ground wire) acts as one of the current-carrying signal conductors. The center conductor enclosed by the shield is commonly known as the “hot” conductor. Unbalanced audio cables do not reject noise as well as balanced lines. Unbalanced lines are typical in-home hi-fi type systems and on the outputs of electronic musical instruments. These work well if the distance between the components is short, the signal level is relatively high and all of the electronics used in the system are plugged into the same AC outlet.

TROUBLESHOOTING

PROBLEM	SOLUTION
No power	1. Make sure the unit is plugged in and the power switch is in the ON position.2. Check that the power cable is plugged in tightly to the unit.3. Check and replace the fuse if necessary. See fuse replacement diagram on the next page.
No sound	1. Check that all appropriate cables are plugged in correctly.2. Check the Master Volume settings.3. Be sure Volume and Gain of appropriate channels are set above 0 level and matched correctly.4. Be sure your microphone is on.5. Make sure fader and balance are set to center positions and levels are increased.
Noise	Turn down the channel gains one by one. If you don’t hear the sound then the problem is either with the channel or whatever device is plugged into it. Unplug the device, to see if the sound disappears. Make sure you are using a proper cable. For ‘K cables, there are 3 types: instrument, TS (unbalanced), and TRS (balanced). Check the requirements of the connected gear and make sure you are using the appropirate cable.
Buzzing sound	Make sure you are using a proper cable. For W cables, there are 3 types: instrument, TS (unbalanced), and TRS (balanced). Check the requirements of the connected gear and make sure you are using the appropirate cable.
Bad Channel	1. Check that the EQ is set up properly.2. Check channel gain.3. Check channel level.4. Check that the channel pan is set to the 12 o’clock position.5. Try setting up the same source signal on a different channel. Make sure to use the same settings as the suspect channel.6. If using a microphone, make sure that it does not require phantom power.
Bad Output	1. Make sure the main level is turned up.2. Check that the EQ is set up properly.3. Make sure the aux return level is not maxed out.4. Unplug devices from other line level outputs just in case one of the devices has a problem.
Bluetooth Pairing Fails	1. Check to see that both devices are turned on and that your Bluetooth device is discoverable.2. Turn both devices off and then on again.3. Make sure you’ve selected the proper source.4. Make sure that the Bluetooth device is within 5 feet of the unit.5. Move both devices away from other Bluetooth devices, microwaves. wireless routers, and other electronics.6. Make sure that all 3 volume controls are set properly (see Bluetooth section for volume settings).7. Make sure that the unit is not paired to a previously paired device.
