Front Panel - Focusrite ISA 828 User Manual

Front Panel

Instrument Inputs (Inputs 1-4)
Input Stage
Activates a gain range
of 30-60 across the
Gain (stepped) dial
(the default is 0-30)
Phantom Power switch
Eight numbered sections are included on the front panel for setting up each of the eight analogue inputs.
Input
Pressing Input steps through each of the three inputs, as indicated by the corresponding LEDs. When the Mic LED is lit,
the microphone input is active etc. Hence a mixture of microphone, line and instrument inputs may be selected across
the eight channels simultaneously. Note that only inputs 1-4 can be used for instruments however.
XLR inputs for microphones and TRS 1/4" inputs for line-level sources are available on the rear panel. TS 1/4" inputs for
instruments are available on the front panel (inputs 1-4 only).
Mic Input Gain
With the Mic input selected, the user has access to the full gain range in 10dB steps from 0dB to +60dB (yellow legend).
The gain range is split between two gain modes depending upon the status of the 30-60 switch (see description on page 6).
