Speakers -
1 .
Left channel
Gain Control-
2 .
continuous adjustment for full power output
Input Mode -
3 .
when the switch is out, the amplifier will accept
speaker level and high output RCA connections . When this switch
is in, it provides extra sensitivity for lower input voltage RCA
(refer to item 4 below)
RCA Input -
4 .
accepts Low Level RCA Inputs (400mV-8V) from a
head unit, preamplifier, or equalizer . XtR amplifiers can also
accepts High Level speaker Inputs (200mV-4V) from an oeM
stereo . these inputs are configured by the Input Mode switch
position (refer to item 3 above)
RCA Line Output -
5 .
provides easy connection to additional ampli-
fiers . note that some oeM stereo headunits may sense the
attached load and may turn off their speaker outputs if expected
load conditions aren’t achieved
X-Over Frequency Control (Flat / All Pass output)-
6 .
adjusts the
frequency (50Hz–2000Hz) of the crossover for the HPF (High-Pass
Frequency Control) and the LPF (Low-Pass Frequency Control)
X-Over (cross-over) -
7 .
activates LPF (low pass crossover), FLAt (all
pass), or HPF (high pass crossover)
Speakers -
8 .
Right channel
Infrasonic (Subsonic) Switch -
9 .
when on, this cuts off extremely
low bass frequencies (below the range of human hearing, that
speakers cannot effectively reproduce) . A high pass filter is
engaged when the sub sonic switch is on . this improves efficien-
cy of the amplifier’s power supply, improves sound reproductive
performance, and reduces chances of damaging the subwoofers .
the subsonic filter is 12dB/octave @ 24Hz
Bass Boost Rear -
10 .
continuously adjusts from 0 to 18dB of boost
centered at 45Hz . only available on the XtR5002
