NOTE: It is safe to connect most modern dynamic
microphones to the microphone inputs when
phantom power is activated. However, some
older ribbon microphones may be damaged
by phantom power and certain unbalanced
line level devices may malfunction or
produce an audible hum when phantom
power is turned on. Use the phantom power
only when using a condenser microphone.
Also, if you activate the phantom power with
the volume turned high, it could produce an audible popping sound.
15. AUX IN
This is the unbalanced input. This input can be used to connect a tape player or other sound sources.
Input Level : -30dBV ~ +6dBV.
16. PRE/POST OUT
PRE OUT : This is the unbalanced output. This output can be used to record the signal from the unit.
The output level is not controlled by the master volume.
Output Level : 0dBV.
POST OUT : This is the unbalanced output. This output can be used to monitor the signal with a monitor amplifier.
The output level is controlled by the master volume.
Output Level : 0dBV.
17. MIC INPUT: CH1 – CH6 (or LINE INPUT)
These inputs are suitable to receive signals from microphones. XLR inputs are balanced.
Input level: -60dBV ~ -16dBV
When another line level source is connected to one of these terminals, adjust the trim volume to the -16dB
position. The phantom power must be off or the line level source could be damaged.
18. INPUT GAIN CONTROLS (TRIM VOLUME)
These are the trim volume controls for each much input to control the input gain.
When adjusting the input gain, make sure that the levels are not set too high or it may cause noisy or
distorted output.
