High Level Input Wiring The high level input(s) should only be used when your head unit lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! 2-Channel Amplifiers PH2.500, PH2.600, PH2.800, PH2.1000, PH2.1300, and PH2.1500 Remote Subwoofer Level Control R POWER R L HIGH LEVEL INPUTS LOW INPUTS L 100mV-2V 2V-8V INPUT SENSITIVITY min max INPUT LEVEL 0 +18dB 50Hz 500Hz HIGH FULL LOW BASS BOOST HIGH PASS MODE FREQUENCY CROSSOVER 45Hz 90Hz LOW PASS FREQUENCY PROTECTION REMOTE SUBWOOFER LEVEL CONTROL TWO C HANNE L M OSF ET POWE R A MPL IFIER R+ R- L- L+ To Speaker Terminals of head unit 4-Channel Amplifiers PH4.400, PH4.500, PH4.600 and PH4.700 CH CH CH CH 4+ 4- 3- 3+ To Speaker Terminals of head unit Remote Subwoofer Level Control CH3/4 CH1/2 CH CH 4 3 CH1 CH3 HIGH LEVEL INPUTS CH CH CH2 CH4 2 1 LOW INPUTS 100mV-2V 2V-8V max 500Hz 90Hz high low BASS BOOST CH3/4 min 50Hz 45Hz INPUT SENSITIVITY INPUT LEVEL high pass low pass CH1/2 max 500Hz 90Hz full mode 0 +18dB CROSSOVER REMOTE SUBWOOFER LEVEL CONTROL min 100mV-2V 2V-8V 50Hz 45Hz high full low POWER PROTECTION FO UR C HANN EL MO SFET POWE R AMPLIFIER CH CH CH CH 2+ 2- 1- 1+ To Speaker Terminals of head unit PHANTOM MOSFET Amplifier User's Manual - page 8
