2 A Tour of the MultiMix FireWire

Line Inputs (Channels 5 – 12)

Unlike channels 1 – 4, the line inputs on channels 5 – 12 are stereo inputs that have left and right inputs. If you’re using one of these channels as a mono input, plug your instrument into the left input. Channels 5 – 12 don’t have the extra gain found on channels 1 – 4 because most line-level instruments don’t require the extra boost.

Synthesizers and other electronic instruments will work especially well on these channels. These inputs are also good for connecting CD players or tape decks, as these audio sources don’t require extra gain.

S/PDIF Digital Output Jack

The digital output jack is used to send the stereo audio signal to an Alesis Masterlink or any other recording device such as a DAT recorder or a PC with an S/PDIF enabled sound card installed.

Always use a high quality cable when connecting the DIGITAL OUTPUT JACK to your recording device. We recommend that you use a cable that is specifically designed to carry a digital signal and does not exceed 5 meters (16.4 ft) in length.

PHONE Jack

The headphone jack accepts 1/4” jacks. If your headphones are 1/8”, you can find a 1/8” to 1/4” adapter in most electronics stores.

AUX RETURNS

These are the 1/4” jacks where you connect the outputs of an external effects processor or other audio source. Each aux return gives you 15dB of gain that can be controlled by the AUX RET A and EFFECTS / AUX RET B LEVEL knobs in the mixer’s output section.

AUX SENDS

And this is the 1/4” jack where you connect the cable that’s going into the input of an external effects processor. The aux sends give you 10dB of gain that can be controlled in the AUX section of each channel input.

ALT 3/4 OUT

These jacks are the outputs for the MultiMix’s extra stereo bus. This signal includes channels whose MUTE / ALT 3/4 switch is activated.

2-TRACK

The 2-TRACK IN and OUT jacks are standard RCA jacks. You’ll use the OUTs for mixing to a tape deck or other recorder. With the INs you can bring in a signal, which can be monitored and

Any audio signal that is routed to the MAIN OUTPUTS will also be sent out of the DIGITAL OUTPUT jack. The level is controlled by the MAIN FADERS. The DIGITAL OUTPUT mirrors the output from the MAIN OUTPUTS.

The S/PDIF output operates by default at 44.1kHz. However, if the mixer is being used with a computer and the sample rate on the computer is set to 48kHz, the S/PDIF digital output will operate at 48kHz as well.

If you are using an effects device with only a mono output, plug it into the left return of STEREO AUX RETURN. It will appear in the center of the stereo spectrum, and not to the left.
