• Check that remote DC terminal has at least +12v DC. • Check that there is battery power on the + terminal. • Check all fuses. • Check that Protection LED is not lit. If it is lit, shut off amplifier briefly and then repower it. High hiss or engine noise (alternator whine) inspeakers. • Disconnect all RCA inputs to the amplifier(s) – if hiss/noise disappears, then plug in the component driving the amplifier and unplug its inputs. If hiss/noise disappears, go on until the faulty/noisy component

2. Adjust the amplifier LEVEL control(s) to an average listening position. 3. Turn the head unit volume all the way down, and listen for background noise. 4. Start your vehicle, and again, listen for background noise. 5. By fine tuning the LEVEL control(s), you can reduce background and engine noise, if present. These adjustments should only be made once. After that, use the head unit volume control to adjust the system volume, not the LEVEL control(s). CAUTION: Never turn the LEVEL control(s) u

If the amp is being used to power a crossover system, set to either HPF or LPF as needed. 5 Crossover Mode Switch Input Level Control Use this control to match the output of the head unit to the amplifier. If distortion is present, reduce the setting of this control. 4 3 Power Supply Terminals Protects the amplifier as well as the automobile electrical system from short circuit conditions. 2 Fuse These terminals are 14K Gold plated for high conductivity and minimum impedance loss.

Legacy has utilized the latest electronic technologies in order to deliver a superb listening experience. This innovative system has been designed utilizing a 12 V DC Negative Ground power supply. The LEGACY Blue Diamond Series amps incorporate two to eight MOSFETS in the different models. This design produces enough available voltage to supply the main amplifier sections, and still have a huge amount of reserve voltage for peak “high demand” situations. The Legacy line has been designed to ensu

Follow these steps: 1. Set the volume control on your head unit to about the 2/3 position. 2. Adjust the amplifier LEVEL control(s) to an average listening position. 3. Turn the head unit volume all the way down, and listen for background noise. 4. Start your vehicle, and again, listen for background noise. 5. By fine tuning the LEVEL control(s), you can reduce background and engine noise, if present. These adjustments should only be made once. After that, use the head unit volume control to adj
