To a stereo PA system or instrument amplifier

Balanced

Check to see if your amplifier can accept balanced inputs. If so, connect the [MAIN OUT BALANCED] jacks of the Multimix 12R to the input of the amp using a 3-conductor cable, with a 1/4" TRS plug on one end, and the connector used by the amp (usually a 1/4" TRS connector; sometimes an XLR or terminal strip) on the other.

•You may also connect the [MONITOR OUT] jacks of the mixer to your amplifier. This will allow you to switch between hearing 2-track playback and the stereo output of the mixer, using the front panel monitor switch.

Unbalanced

If the amp is unbalanced, use a standard shielded "patch cord" with 1/4" connectors.

To a mono system

If your PA system or amplifier isn't stereo, connect either the left or right MAIN OUT jacks to the input of the system. Make sure that all [PAN] controls are in the center or turned to the side you're using.

To a stage monitor (foldback) system

If your PA system has a separate amplifier and speaker system for monitors, connect a cable from the [AUX 1 PRE AUX SENDS] jack to the amp input, in the same manner as above. The Aux 1 system is a pre-fader, post-EQ send with a balanced/unbalanced output. In most stage monitor situations, we recommend connecting a third-octave graphic equalizer such as the Alesis MEQ-230 between the mixer and the amp to control feedback.

The Aux 1 output may be connected in the same way for a number of different applications such as:

•Headphone cue feed for multitrack recording

•Separate broadcast mix from a PA system

•Zone feed for a separate region of a PA system
