- 1/2CH X-OVER: FULL - 3/4CH X-OVER: LPF The following example shows how to create a 3 channel system by mono bridging channel pair 3 / 4. In order to create a 2 channel system, simply follow Crossover frequency control checklist: the example to also mono bridge channel pair 1 / 2. Channels 1/2: - HI PASS: N/A Interconnect cable checklist: - LOW PASS: N/A - Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit with good quality RCA cables. Channels 3/4: - A MONO signal source is required to bridge channel pair 3/4, such as would be - HI PASS: N/A available from the mono sub bass output of an active crossover, whether - LPF: 11 o’clock standalone, or built into a head unit or equalizer. If you only have 1 set of RCA outputs from your headunit, you can simply connect those to the inputs for ch TIP: If you are using the mono sub bass output of an active crossover, there is 1/2 and switch the MODE to 3ch. The amplifier will auto sum the signal and nothing wrong with switching in the low pass filter in these amplifiers for a provide mono output for bridged channels 3/4. steeper low pass rolloff. Important: Do not be tempted to connect the hot, or positive outputs, from any source together to obtain a mono signal, as this could very well damage the Level control checklist: output stage of that source. - Refer to the section “Setting up systems after installation for best performance” - It is necessary to feed the SAME signal to both left and right inputs via a Yadapter RCA cable.

SUBSONIC: This setting acts as a low frequency cut off for your system bass reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the Subsonic to 25Hz, the amplifier will not play frequencies below 25Hz but will play frequencies from 25Hz to the chosen Low Pass frequency. BASS BOOST: This setting is a fixed bass boost at 45Hz that is variable from 0-10dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to your subwoofers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a low volume or a low recording quality as this can result in high distortion and possibly clipping. LOW PASS: The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. The 12 o’clock posi...
