The new Coustic D-block amplifiers deliver the cleanest music you’ve ever heard at any power level in the 12-volt environment. Besides the sleek contoured design, these amplifiers have all the latest and most sophisticated audio features. This manual offers you a guided tour of all these exciting features. For the best sonic reproduction, please follow the installation suggestions and recommendations as closely as possible. The time you spend will prove to be worthwhile when you sit back and enj

This will give you the best sound and signal-to-noise ratio. Besides better sonic reproduction, proper input sensitivity 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. REMEMBER that the input gain control has nothing to do with the power output of

SETTING UP & USING REMOTE SUBWOOFER GAIN CONTROL (R S) If you are using the R S control, make sure to take this into account during set-up procedures of the subwoofer amplifier. You should set the system up with the R S plugged in, and with the level knob turned all the way down (counter clockwise). NOTE: the R S ONLY works when you’ve selected the LPF (low-pass) crossover configu

Figure 3: Upright Mount on Horizontal Surface Figure 4: Parallel Mount on Vertical Surface The amplifier may be mounted upright on a horizontal surface (see Figure 3) or parallel to a vertical surface (see Figure 4). However, the amplifier should never be mounted upside down (see Figure 5) for the simple reason that the hot air generated by the amplifier would have to go through the unit internally on its natural upward path (i.e., "feedback" into the unit) and would result in increased internal
