Xtant2.2/Xtant4.4 Amplifier Owner’s Manual
ADJUSTMENTS
CROSSOVER SELECTION
The Xtant2.2 amplifier has built-in High-pass/Low-pass crossover
1. When HP (High-pass) is selected, the amplifier will be devoted to
mid/tweeters.
2. When LP (Low-pass) is selected, the amplifier will be used to drive
woofers/subwoofers.
3. When BP (Bypass) is selected, the amplifier is used as a full range
amplifier.
The Xtant4.4 amplifier has built-in High-pass crossover for the front channels and a High-
pass/Low-pass crossover for the Rear channels.
1. When HP (High-pass) is selected, the outputs will be devoted to mid/tweeters.
2. When LP (Low-pass) is selected, the outputs will be used to drive woofers/subwoofers.
3. When Full (Full Range) is selected, the outputs is used as full range
outputs.
CROSSOVER FREQUENCY SELECTION
Crossover frequencies for the on-board crossovers are adjustable 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 Left and Right Gain controls 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 or tape 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
Left and Right Gain controls
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.
A.R.C.
Active Resonance Control (A.R.C.) is a level adjustment that reduces the res-
onant frequencies inside the vehicle to improve the mid-range sound quali-
ty. Turn this control clockwise or counter-clockwise until the vocals of the
music are up-front and centered in the vehicle. The mid-range sound
should be smooth and detailed.
