SAC 2090 CONTROL FUNCTIONS
1. RCA inputs
2. Input Level Controls
3. Crossover Selector (HPF/FLAT/LPF)
4. Status LED indicators
5. CORSSOVER
RCA cables marked FRONT or REAR from head unit or other line level device should be connected here. Use both inputs ( L& R) for front and rear stereo.
This is for adjusting input sensitivities. To adjust the sensitivity, turn the controls fully counterclockwise to minimum. Adjust the radio/head unit volume knob to maximum
volume, and then turn the level controls on the amplifier clockwise until audible distortion occurs.
This switch allows these two amplifier channels to play full range, low pass, or high pass. In the LPF (Low Pass Filter) position, all the high frequencies are filtered out
and the amplifier produces only low bass frequencies.
On the contrary, in the HPF position, the low frequencies are filtered out and allowing the amplifier to play mid and high frequency. If the amplifier is used to power
subwoofers, set the crossover switch to LPF. If the amplifier is used to power midrange and tweeters or coaxial type speakers, set the crossover to HPF.
Switch the crossover to FLAT when amplifier is used in Tri mode configuration or when full range speaker are used.
GREEN indicates the normal operating condition: the amplifier is ON. RED indicates the Amplifier is protection
This is for adjusting LPF & HPF frequencies; In the LPF position, to adjust the frequencies from 66Hz-275Hz, all the high frequencies are filtered out and the amplifier
produces only low bass frequencies. In the HPF position to adjust the frequencies from 40Hz-178Hz, the low frequencies are filtered out and allowing the amplifier to
play mid and high frequency.
