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
