Description
The IPro™ One is a microphone or line input processor
that is especially designed to optimize audio signals
(low or high impedance) for recording or live applica-
tions. It is an improvement over a standard mixer's
channel strip for direct recording of a microphone or line
instrument since it has functions not found in other ana-
log signal processors.
The IPro One has separate mic and line inputs. The line
input has level control. The mic input has polarity, 20 dB
pad, +48 V phantom power, on/off switch, and an
adjustable low cut filter with gain control.
The parametrics section have two adjustable EQ's. Both
have on/off switches, and the second has a switch to
side change into the dynamics section.
The compand/limit section has an on/off switch, external
side change enable, expander with ratio and threshold
controls, and compressor with Ratio and Threshold con-
trols. there is also a makeup gain and limiter threshold.
SmarTube™ enhancer has adjustable frequiproency and
amount. This adds tube-like characteristics to the signal.
The Main Section has a dry/wet blend control and a
main output level control. There is an independent
headphone out with level control.
The metering section has gain reduction dB and output
level dB with the output switchable to preamp in.
