Multimix 12R Reference Manual 5
INSTALLATION
Unpacking
The Multimix 12R box should contain:
1. The mixer itself
2. A packet of literature along with this manual
3. An AC power cable
AC power
READ ALL SAFETY WARNINGS IN THE PREVIOUS SECTION OF
THIS MANUAL TO ENSURE SAFE OPERATION OF THIS UNIT.
Connect the Multimix 12R to the specified power using the AC cable
supplied with the unit. The AC cable is removable. If the distance to
your AC outlet is longer or shorter than the supplied cable, you may
substitute an approved standard NEMA-to-CEE power cable of the
correct length, available from most electronics stores.
Grounding
CONNECT THE MULTIMIX 12R TO A PROPERLY GROUNDED
OUTLET ONLY. DO NOT USE ADAPTERS WHICH REMOVE THE
SAFETY GROUND PROTECTION OR CUT OFF THE GROUNDING
PRONG ON THE POWER CORD. Proper grounding is essential for
user safety and low noise. If you experience 60-cycle hum in your
sound system as a result of different ground potentials between
different units in your system, plug all units into the same AC circuit (if
the total power load allows) and make sure other devices in the
system are properly grounded themselves. The Multimix 12R features
balanced inputs and outputs, so if it is properly connected to other
balanced units, AC ground potentials will not affect the audio. If you
cannot get rid of ground loops, consult a professional electrician
familiar with sound system power designs.
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.
