1 1/4" INSTRUMENT Input (only channel 1 and channel 2)
These two high-impedance 1/4" instrument inputs have been designed to
connect instruments such as electric guitar or bass directly into the unit
without passing through an external D/I Box.
NOTE: please do not use the built in pre-amp of active instruments (when
available) in order to avoid distortion caused by over-driving the input signal.
FRONT PANEL
2 GAIN control
This control adjusts the input sensitivity of the relative channel. Through
this control audio signals from the outside world are adjusted for an optimal
internal operating level. When a signal is applied to the XLR inputs on the
rear panel you have 0 dB of gain with the GAIN control turned down completely.
You get 60 dB of gain with this control turned all the way up.
3 +48V (phantom power) switch
Professional condenser microphone requires the phantom power. This is a
low-current DC voltage delivered through pin2&3oftheXLRmicrophone
connector. Push the +48V switch to activate this function, and it will light
up to confirm that the function is active. Dynamic microphone does not need
the phantom power but this will not give them any damage. However, old
ribbon microphone can be seriously damaged by phantom power. We advise
you always to check the manual of your microphone and see if it requires
phantom power or not.
4 HIGH-PASS FILTER
This filter provides an 80 Hz high pass filter for each channel. When you press
it will light-up confirming that the function is active. This filter is useful for
eliminating extraneous low-end information from the input signal. Frequencies
at 80Hz and below are cut from the incoming signal. This filter is useful in
eliminating low frequency noise such as air-conditioning rumble or for reducing
the sound of footsteps or other types of vibration from being transmitted
through the microphone stand into the microphone.
