DIGITAL SR AMPLIFIER Bridge connection: wire the “hot”/positive lead to the “+” terminal of CH1, the “common”/negative lead to the “-” terminal of CH2. ※ NOTE : Before connecting speakers to the unit, be sure to disconnect the AC power cable. Make certain that the total impedance is not less than the rated impedance indicated. Do not put the speaker cable close to input signal cable. 4.
DIGITAL SR AMPLIFIER 7. MODE SWITCH Mode selection switch for either CH1/CH2 stereo or BRIDGE mono mode (1) CH1/CH2 MODE Input signal of each channel will drive each channel independently. Input signal of CH1 drives Amp output of CH1, Input signal of CH2 drives Amp output of CH2. In this case volume can be controlled independently on both channel. (2) BRIDGE MODE The bridge mono mode combines both channels to create one larger mono channel.
DIGITAL SR AMPLIFIER Installation installation of Caution The Cooling Vents are provided for ventilation and to ensure reliable operation of the unit and to protect it from overheating. These openings must not be blocked or covered. The unit should not be placed in a built-in installation unless proper ventilation is provided.
