Xtant3.1/Xtant6.1 Amplifier Owner’s Manual
ADJUSTMENTS
CROSSOVER FREQUENCY SELECTION
Your Xtant amplifier has a built-in low-pass filter offering continuously
adjustable crossover frequencies between 40-120Hz Hz. Adjust the setting
according to your speaker component specification or to your particular
preference—counter-clockwise for a lower frequency, clockwise for a higher
frequency.
BALANCED INPUT ADJUSTMENT
OFF POSITION: when using Low Level (RCAs)
without
a Line Driver
(100mV-7.5V)
ON POSITION: when using High Level (speaker) inputs with Xtant High
Level Adapters (HLA) or Low Level (RCAs)
with
a Line Driver (7.5V-17V)
GAIN CONTROL ADJUSTMENT
1. Turn the Gain control all the way down (counter-clockwise)
2. Set the volume control of the source unit to approximately
2
⁄
3
of its maximum output
3. Turn the balance control of the source unit to its center position
4. Leave the tone (bass/treble) controls at their usual position
5. Play a CD track with wide dynamic range
6. Use the Bass Boost Control to enhance the bass performance (if desired)
7. To locate the optimum input sensitivity setting, turn the Gain control clockwise until audible
distortion starts to develop. Turn the sensitivity control counter-clockwise slightly to minimize the
distortion.
8. If you often switch between sources (CD, tape, radio, etc.) you will need further adjustment
since radio output level differs from that of CD or tape. In this case, you need to locate a balanced
sensitivity setting which is best for the output level of your sources.
BASS BOOST CONTROL ADJUSTMENT
Select a boost level between 0dB and +12dB to enhance the bass perform-
ance for your sound system. Remember that every 3dB of boost costs you
twice as much in power. Make sure to set the final gains after setting the
Bass Boost to work best with your subwoofer/enclosure combination.
RLC PORT
If you are using the RLC control, make sure to take this into account during
set-up procedures. Set-up the system with the RLC plugged in and with the
level knob turned all the way up (clockwise). Adjust according to taste and to
work best with your subwoofer system.
SUBSONIC FREQUENCY SELECTION
The subsonic filter maximizes your Xtant amplifier’s output when a specifi-
cally tuned subwoofer system is used. For example, if your subwoofer sys-
tem is designed to play 40Hz-80Hz only, setting the Subsonic Filter to 40Hz
will prevent the amplifier from wasting power trying to reproduce signals
below 40Hz. The subsonic frequency settings are continuously adjustable
from 20Hz-80Hz. Select the setting according to your preferred subwoofer
system specification or to your particular preference.
OFF POSITION: defeats Subsonic Filter
ON POSITION: engages Subsonic Filter
