SM2-400 / SM2-1000 / SM2-1200 / 2 CHANNEL AMPLIFIER APPLICATIONS

FULL RANGE STEREO

This is the most basic application for the Street Machine Series 2 channel
amplifiers.
1. Interconnect cable checklist:
Connect the LINE INPUTS to the Radio/CD with good quality RCA cables.
2. Crossover Switch:
The X-OVER switch must be in the FULL position.
3. Crossover frequency control checklist:
N/A for full range operation.

This application illustrates the basic mono bridging method for all Street
Machine 2 channel amplifiers.
Interconnect cable checklist:
A MONO signal source is required, such as would be available from the
mono sub bass output of an active crossover, whether stand alone, or built

hot, or positive outputs, from any source together to obtain a mono signal, as
this could very well damage the output stage of that source.
It is necessary to feed the SAME signal to both left and right inputs via a Y-
adapter RCA cable. Connect the mono speaker positive terminal to the
RIGHT +, and its negative terminal to LEFT -.

The HIGH LEVEL inputs are used when the radio/CD player does not have RCA cable outputs. You can connect the radio/CD player speaker wires directly to the
amplifier via the high Level Inputs.

Refer to the section "Setting up systems after installation for best
performance".
NOTE: Minimum final loudspeaker impedances:
4 &-2-Ohms stereo mode or 4-Ohms mono mode
This amplifier will not do 1-Ohm stereo or 2/1-Ohm mono operation.
Switch setting checklist:
- The AMPLIFIER X-OVER switch must be in the FULL position.
Crossover frequency control setting checklist:
N/A for full range operation.
TIP: If you are using the mono sub bass output of an active crossover, there
is nothing wrong with switching in the low pass filter in these amplifiers for a
steeper low pass roll-off.
Minimum final loudspeaker impedance:
- 4-Ohms mono.
Use both connectors for 4 CH amplifiers
