13. PHANTOM POWER SWITCH
These switches turn the phantom power supply on
or off for each channel.
When the switch is pushed, +24V DC power is
supplied to the pin 2 and the pin 3 of each XLR
jack. Use phantom power when you connect a
condenser microphone, which requires an
external power supply.
NOTE
: It is safe to connect most modern dynamic
microphones to the channel 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 you use a condenser microphone.
If you press the phantom power switch when the channel volume and master volume is at the high volume
level, it may cause audible pop sound.
14. 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.
15. 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.
16. MIC INPUT : CH1 - CH6 (or LINE INPUT)
These inputs are suitable to receive signal from microphones. XLR inputs are balanced input.
Input Level : -60dBV ~ -16dBV
When other line level source is connected to one of these terminals, adjust the trim volume to -16dB position.
The phantom switch must be off or not the line level source may be damaged.
17. INPUT GAIN CONTROLS (TRIM VOLUME)
These are trim volumes of each mic inputs to control the input gain.
When adjusting the input gain, make sure that the levels are not set too high, or not it may cause noisy or
distorted output.
