INPUT, POWER SUPPLY AND OUTPUT
5
1- Remote input (+): connect to the player antenna output.
2- Positive power input (+12Vdc): connect to positive battery pole.
3- Negative power input: connect to vehicle chassis ground.
4- Protection fuse: 20A
5- Output terminals.
6- Blue led: amp on
Low impedance input (wire): can be wired directly to cd / dvd players power outputs. This input has an automatic turn on
system that detects if the player is on, turning the amplifier without using a remote signal. 1kohms impedance.
High impedance input (RCA): used with RCA outputs. 22kohms impedance. Needs remote signal.
BD-250.1 is a mono amplifier so the two inputs are shortened and there is only one output (BRIDGE) capable of driving
250Wrms@4 ohms.
BD-250.2 is a stereo amplifier capable of driving 2 x 125Wrms @ 2 ohms or 1 x 250Wrms @ 4 ohms (BRIDGE). To use the
amplifier in bridge mode is necessary to apply the same signal to both inputs using a Y cable for RCA (high impedance)
input or jumper for wire input (low impedance).
