MX-206 Rear Panel
1. Power Switch - This switch turns on AC power
to the mixer, lighting the blue front panel LED. If
the switch is pressed but the LED is still off,
check to see that the AC power cord is not
detached.
2. Microphone Input - The microphone input is
an active balanced type with a nominal
impedance of 1200 ohms. Its noise
performance is best with a 200 ohm
microphone. The Mic input connector is a
standard 3-pin XLR female.
3. Input Pad - The Pad is a 20dB attenuation
switch on the rear panel for use with each XLR
microphone input. It should normally be left in
the "out" position for best signal to noise ratio
and should only be used when the input is
being overdriven with the Input dB (gain) switch
at its minimum setting.
4. Tape/CD Input - Tape Output - The stereo
inputs on RCA connectors have a nominal
operating level of -10dBu to match most tape
decks and CD players. The tape outputs are -
10dBu "premaster", so they are not affected by
the settings of the output controls.
5. Mono Transformer Balanced Output - The
mono transformer output uses a male XLR
connector and provides total isolation for 600
ohm lines. The output is controlled by the Mono
level, with a nominal operating level of +4dBu.
Note: The transformer-balanced output is
designed to drive up to +24dBu into a 600 ohm
load. Because of the nature of an output
transformer, the output level increases as the
impedance of the terminating load becomes
higher than 600 ohms. Whereas a "direct-
coupled" output stage like that of the stereo
outputs will not change as the load changes,
any transformer used in an audio path is
affected by its termination impedance. Since
line level inputs on audio devices are typically
10K or higher, expect a slight increase
(2.5dB) in output level when driving high
impedance inputs with the mono. The output
meters will reflect the levels present on the
stereo outputs, regardless of the load on the
transformer output.
6. Stereo Outputs - The Stereo Outputs are
controlled by the left and right master. They are
1/4" balanced TRS jacks with a nominal
operating level of +4dBu into any load.
Installation
Always switch the unit off before making substantial changes to the settings or connectors. Use
four screws and washers when rack mounting. This unit has specific electrical and signal
requirements, please take special care to double check all connections and settings and refer to
the specifications section of this manual. The unit should be connected to a standard 3-wire
grounded electrical outlet supplying 100-240 Volts, 50-60 Hz. To reduce the risk of ground
loop hum, connect all audio equipment to the same electrical power source. Removal of the
ground pin is both unlawful and dangerous, as a potential shock hazard could result. Overall
power consumption is less than 30 watts.
NOTE: The power switch does NOT isolate the appliance from mains. Make sure the mains
power socket or an alternative disconnect device is near by and easily accessible. When the
product is connected to mains, the line-filter and the input of the fuse are energized.
