If the car stereo does not have a system remote control terminal, connect the male terminal to the power terminal through the ignition switch. 23 24 • Bass Boost Level Control and Bass Boost Frequency Control can be adjusted only when the LPF/HPF select switch is set to a position other than HPF . You can select a bass boost frequency from 40 to 120 Hz with the bass boost control. Bass Boost Frequency Control Bass boost level control can boost the level around the frequency selected by the bass boost frequency control from 0 to 12 dB. Bass Boost Level Control • Set the gain control to “NORMAL” when this amplifier is connected to a Pioneer car stereo with RCA output jacks. If the sound level is too low or distorts, adjust the gain control. • Adjust the gain control to the “MIN” side of “NORMAL” when this amplifier is connected to a Pioneer car stereo (High voltage output type). If the sound level is too low, even when the volume of the car stereo used along with this power amplifier is turned up, turn gain control on the back of the power amplifier clockwise. If the sound distorts when the volume is turned up, turn the gain control counter-clockwise. Gain Control Setting the Unit If the LPF (LPF/HPF) select switch is set to LPF (or HPF), you can select a cut off frequency from 50 to 120Hz.

Connecting the Speaker Output Terminals GM-X822,X722 25 26 The power amplifier is basically a twochannel/one-channel bridgeable amplifier, but three channels can be achieved by combining the stereo and mono modes using inductors and capacitors. Three-channel mode (stereo + mono) Speaker (Mono) One-channel mode (mono) (Left) Speaker (Right) Two-channel mode (stereo) • When connecting to the speaker input, do not connect the RCA output. • When connecting to the RCA input, do not connect the speaker input. The speaker output mode can be two-channel (stereo), one-channel (mono), or threechannel (stereo + mono). Connect the speaker leads to suit the mode according to figures on the following pages. Connecting the Speaker wires Woofer/sub-woofer (Mono) Mid/mid-bass (Right) L1 C2 High/mid-high (Right) Mid/mid-bass (Left) C2 • Inductors (L1 and L2 in the diagrams) act as low-pass filters. Capacitors (C1 and C2 in the diagrams) act as high-pass filters. Inductors (L) are used for the woofer/sub-woofer, and capacitors (C) are used for the high/mid-high. • Remember when bridging an amplifier it will see only half of the original speaker impedance. Therefore, you must use speakers that have ratings of 4 ohms or higher. If you use speakers that have lower impedance ratings it may cause damage to the amplifier. • When the inductors and capacitors are connected to the speaker wires, secure or solder them so they cannot be pulled loose. Tape or use heat shrink on the joints to prevent short circuits.

The inductance (L) and capacitance (C) will determine the frequency (fc) that the speaker will reproduce. Refer to the chart below to determine the components required. • Use the capacitors specified. Non-polarized capacitors rated at over ±25 V should be used for C1 and C2 in the diagram. Because of the voltage output of the amplifier, it is very important to use non-polarized capacitors rated at or over 25 V. This will prevent a safety hazard.
