Installation
Use clean power
The Multimix 12R's internal power supply is designed to filter out most AC line noise. However, it is still good practice to plug your sound equipment into an AC circuit that is not shared with lighting dimmers, refrigerators, air conditioning units, or other appliances that may induce noise into the power system.
Power switch
The POWER switch is located on the back panel. A power indicator is on the front panel next to the meter. Avoid turning the power switch on or off while the Multimix 12R is connected to a live amplifier.
Mounting
The Multimix 12R may be rack mounted in a standard EIA 19" rack, occupying three standard 1.75" rack spaces. Any angle of orientation is acceptable. Note that (as with most audio equipment) if it is mounted into metal rack rails, the chassis ground of all units in the rack will be connected together by the rail. In some cases this is desirable, but if hum is a problem in the system, you may need to install non- conductive rack screws and washers on the Multimix 12R or other equipment in the rack to isolate the chassis grounds from each other.
The mixer may also be used on a table top. To avoid scratching a tabletop surface, apply rubber or felt feet to the bottom of the Multimix 12R.
