Input Controls
Below each channel’s Gain Control, there
is an indicator panel showing which of the
channel’s Input Controls are active. Each
channel has the following input controls:
Phantom Power Switch - There is an
independent phantom power switch for each
microphone channel. When the switch is in
the UP position, this provides full phantom
power (48V ±4V, 10mA per channel) to the
microphone connected to this channel.
Please note that the iD48 will only send
phantom power to XLR connections, the TRS
line inputs will not receive phantom power.
High Pass Filter - Each preamp also includes
a switchable hardware high pass filter that
has a cut-o frequency of 100Hz. This is good
for removing rumble and room noise from
your recordings. The high pass filter can be
switched on and o from the included iD
Software Mixer Application.
-10dB Pad - Each input features a switchable,
hardware -10dB pad to help lower the signal
level when recording particularly hot sources
such as drums. The Pad can be switched on
and o from the included iD Software Mixer
Application.
ADC (Balanced Send & Returns) - Each
channel has a switchable insert point before
the ADC (Analog to Digital Converter) using
the DB25 Inputs and Outputs on the rear of
the interface.
There are three modes that the channel can
be set to.
• Mic
• ADC Direct
• Mic Insert
The ADC light will illuminate when the unit is
set to ‘Mic Insert’ or ‘ADC Direct’ mode to
indicate that this input channel is taking the
signal from the ADC Inputs on the rear of the
unit instead of the Mic/Line Combi Connectors
These settings are referred to as the ADC Path
Settings and are adjusted per channel in the
included iD Software Mixer Application.
