CONNECTION DIAGRAM

FRONT PANEL OVERVIEW

1. VOLUME

Adjust the gain for each channel

2. PAN

Adjust the signal's position in the left-right panorama. For stereo connections, this knob acts as a BALANCE control, attenuating the left side of the signal as the knob is moved rightwards, and vice versa.

3. SEND

Adjust the amount of signal sent to an external effects processor. SEND is "post-fader," which means that the amount of signal you send to the external processor will be affected by the VOLUME setting for the channel.

4. SIGNAL/CLIP LED

When normal signal levels are detected, this LED glows green. To minimize distortion, turn down your input source if the LED flashes RED (clip).

5. MIC/LINE

For the first channel, switch between a MICROPHONE input or the LINE inputs on the rear of the unit.

6. EFFECTS RETURN

Adjust the amount of signal sent back to the mixer from an external effects processor.

7. MASTER

Adjust the output volume sent to the MAIN OUTPUTS.

8. MASTER LEVEL METERS

Watch the master level meters for optimal signal level. The MultiMix8Line's meters indicate 0dB at 0dBu.

REAR PANEL OVERVIEW

1. 8 STEREO OR 16 MONO LINE INPUTS

Plug stereo sources into both the top (LEFT) and bottom (RIGHT) jacks. For mono sources, use only the top (LEFT) jack. Doing this will "normal" the signal to both LEFT and RIGHT inputs. These are unbalanced connections.

Use TS (Tip-sleeve) 1/4 cables for connections. The MultiMix8Line provides a wide gain range suitable for simultaneous use of both -10dbV (consumer-level) and +4dBu (professional-level) equipment.

2. OPTIONAL MICROPHONE INPUT ON CHANNEL 1

Select MIC or LINE for channel 1 using the switch on the front panel. Note that a microphone must be connected to the XLR (3-pin) input and is always treated as a mono signal.

You must select either MIC or LINE. It is not possible for channel 1 to process microphone AND quarter-inch signals at one time.

Note that the MultiMix8Line does not feature phantom power. Ensure that your microphone does not require phantom power for operation.

Once you have connected your sources, adjust their volume, pan position, and aux send levels. (See below for more on Aux Send and Return.)

3. MAIN EXPAND IN and OUT jacks

You can chain together as many MultiMix8Line mixers as you like by connecting the MAIN EXPAND OUT jack of mixer A into the MAIN EXPAND IN jack of mixer B. Continue connecting additional mixers in similar fashion (OUT B into IN C, OUT C into IN D, etc.). Use a stereo (TRS) cable for these connections. The final mixer in the chain will control the MASTER volume for all of the devices connected to all the mixers. Connect the final mixer in the chain to your output device (amplifier, powered speakers, main mixer, etc.) via the MAIN OUTPUT jacks.

The MAIN EXPAND OUT signal is tapped before the EFFECTS RETURN and MASTER controls. Therefore, for any particular mixer, any signal sent from this jack will not be affected by the position of these controls.

4. STEREOMONITOR OUTPUT

This is an additional, unbalanced output that you can connect to a headphone amplifier, auxiliary recorder, or other device. This signal is tapped AFTER the MASTER volume knob: its level follows the MASTER volume setting.

To connect the STEREO MONITOR OUTPUT to stereo equipment with separate Left and Right inputs, use a TRS-to-dual-TS 1/4" cable. A standard "Insert" cable, available from your audio dealer, is ideal for this application. Connect the TRS (stereo) plug to the MultiMix8Line. Then, connect the two separate TS (mono) plugs to the target device, "Tip" signal Left and "Ring" signal Right.

5. EFFECTS BUS LINK

If you own two MultiMix8Line mixers, you can connect them so that they can share one external processor. Use a TRS-to-dual-TS 1/4" cable such as a standard "Insert" cable. Connect the two separate TS (mono) plugs to the EFFECTS SEND of the first mixer, "Tip" signal Left and "Ring" signal Right. Connect the TRS (stereo) end of the cable to the second mixer.

Connect your external effects processor to the EFFECTS SEND and EFFECTS RETURN jacks of the second mixer. The AUX SEND levels from both mixers will now be routed to the effects processor. Control the overall effect level using the EFFECTS RETURN knob on the front of the second mixer.

6. STEREO EFFECTS SEND and RETURN

Connect a reverberation unit (such as the Alesis MidiVerb4) or other effects processor to these jacks in order to add effects to your mix. Connect the input INTO your effects processor to the EFFECTS SEND jacks. Connect the output FROM your effects processor to the EFFECTS RETURN jacks. If you are using a mono effects processor, connect only the LEFT (MONO) jacks of the MultiMix8Line. Using the LEFT (MONO) jack only, the effects return will be heard through both LEFT and RIGHT output channels.

Once your effects processor is connected, use the AUX SEND knob on each channel to adjust the amount of effect applied to that channel.

Consider setting your effects processor to "100% wet" so that it sends only effected signal back to the MultiMix8Line. This will make it easier to dial in just the right effect amount using the channels' AUX SEND knobs and the master EFFECTS RETURN knob.

These are unbalanced connections. Use TS (Tip-sleeve) 1/4'' cables for connections.

7. MAIN OUTPUTS

Connect the MultiMix8Line to its destination output device (amplifier, powered speakers, main mixer, etc.) using the main outputs. These are balanced jacks, so use TRS cables for best results. The MAIN OUTPUT level is controlled by the MASTER volume knob on the front panel.

8. VOLTAGE SELECTION SWITCH

VERY IMPORTANT! Slide the voltage selector to the appropriate setting for your power source.

9. FUSE

The fuse is user replaceable. To ensure proper operation, replace only with a fuse of the rated type as shown on the rear of the unit.

10. AC POWER CABLE

The MultiMix8Line contains a built-in power supply with switchable international voltage. Use an IEC power cable to connect to a power source.
