Connecting the Speaker wires The speaker output mode can be two-chan nel (stereo), oneechannel (mono), or three, channel (stereo + mono). Connect the speaker leads to suit the made according to the figures shown below, ' Do not connect both the RCA input and the speaker input at the same time. Two-channel mode (stereo) Speaker * (Left) (Right) One-channel mode (mono) Lgfq Speaker (Mono) Three-channel mode (stereo + mono) The power amplifier is basically a two- channel/one-channel bridgeable amplifier, but three channels can be achieved by combining the stereo and mono modes using inductors and capacitors, ThreeAchannel mode, two-way system or Mid-high (Right) L1 Woofer (Mono) m % Mid-high (Left) Three-channel mode, three-way system High/midhigh m (Right) Mid/midibass iii] (Right) Woofer/subwoofer U (Mono) L2 aim Mid/midrbass {Hm.1 (Left) Ct HIgh/mid-high (Left) - Inductors (Li and L2 in the diagrams) act as lowpass filters. Capacitors (Cl and C2 in the diagrams) act as highepass filters. Inductors (L) are used for the woofer/subwoofer, and capacitors (C) are used for the high/midihigh. - 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.
