SYSTEM TUNING (INPUT GAIN ADJUSTMENT)

SPKR

INPUT

L+R+

L- R-

Located on the Input Panel, the objective of input GAIN adjustment is to match the output of the source unit with the input of the ampliﬁer. The output voltage of individual source units can vary. Some source units have an output of 200mV and others have 5 volts or more. To cater to these variations, the ampliﬁer has an adjustable gain level that ranges from 100mV to 5 volts. Follow the steps below to set gains.

Besides better sonic reproduction, proper input gain also helps to prolong the reliability span of your ampliﬁer by eliminating excessive internal temperature generated by incompatible source unit output and ampliﬁer input.

Note: Turning the input gain up does not indicate more power. Just more noise. The input gain control is not a power control. If everything is in order, complete the installation by reconnecting the battery ground to the vehicle chassis.

If the Remote Gain is used, connect the plug of the Remote Gain to the port on the panel of the ampliﬁer.

1.Turn the Input GAIN all the way down (counter-clockwise).

2.Set the volume control of the source unit to approximately 3/4 of its maximum output.

3.Turn the balance control of the source unit to its center position (ﬂat).

4.Leave the tone (bass/treble) controls at their usual position.

5.Play a CD or tape track with great dynamic range.

6.Use the Bass Boost Control on the amp to enhance the bass performance (if desired), not the bass on the headunit.

7.To locate the optimum gain setting, ask the person assisting you to turn the Input GAIN control clockwise until audio distortion starts to develop. Turn the gain control back wards slightly to minimize the distortion.

8.If you constantly switch between CD/tape and radio, 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 gain setting which is best for both the output level of radio and the CD.

SYSTEM TUNING (CROSSOVER ADJUSTMENT)

Note: If you are using the Remote Gain, make sure to take this into account during setup procedures of the subwoofer ampliﬁer. You should set the system up with the Remote Gain plugged in and with the level knob turned all the way down (counter-clockwise). The Remote Gain only works when you’ve selected the LP (low-pass) crossover conﬁguration.

CROSSOVER SELECTION

The ampliﬁer has built-in high-pass/low-pass ﬁlters that can be bypassed by sliding the switch to the (FR) position.

1.When the high-pass is selected (HP), the ampliﬁer will be devoted to mid/tweeters.

2.When the low-pass is selected (LP), the ampliﬁer will be used to drive woofers/subwoofers. With this setting, the Remote Gain can directly control the ampliﬁer playback level.

3.When the full range is selected (FR), the ampliﬁer is used as a full range ampliﬁer.

CROSSOVER FREQUENCY SELECTION (FREQ)

Both the high-pass and the low-pass section offer continuously adjustable crossover frequencies between 40Hz and 350Hz. Adjust the setting according to your speaker component speciﬁcation or to your particular preference.

BASS BOOST CONTROl (BASS BOOST)

Select a boost level between 0dB and +18dB @ 40Hz to enhance the bass performance for your sound system. BASS BOOST is NOT free! 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. More is NOT always better!
