The Monoprice MP-DSS4 are low-profile speaker selector boxes that allow you to distribute a stereo high-level (amplified) signal into multiple zones. These models include a manually activated impedance protection circuit that can be turned ON to prevent the impedance presented to your receiver from dropping below an unsafe level of 5 Ohms, regardless of the number and impedance ratings of your speakers. The protecting switch can also be turned off when used as part of a planned system of impedance matching volume controls, allowing you to get the most out of your amplifier. If you are

unsure, consult a professional contractor.

MP-DSS4 have the ability to select between "A" and "B" sources. Above is an 4-position plug on the left rear of the unit which is labeled "A B".This is where the speaker level inputs from the two sources ("A" and "B") are connected. Attach the wires in the same manner as the speaker wires connect to the outputs of the MP-DSS4 unit (see below).

Connecting your Speaker Selector

The terminals on the rear of the speaker selector will accommodate 14 gauge cable which will suffice for even long connections (greater than 100 feet of wire). For shorter distances, 16- or 18-gauge wire will suffice. For behind-thewall installations, we recommend using UL Class 3 approved cable (marked "CL3 ) for compliance with local building " codes. When connecting a speaker and amplifier, it is important to retain the correct polarity. To do this, be sure that the wire attached to the +, red, or positive terminal on the speaker connects to the +, red, or positive terminal on the rear of the selector box. Similarly, the -, black, or negative terminal on the speaker must connect to the respective -, black, or negative terminal on the selector box. Polarity should also be maintained when connecting your amplifiers outputs to the amplifier inputs on the selector box.

Connecting Speaker Cables

1. Route the speaker cables from the amplifier and from each speaker zone to the speaker selector.

2. Strip 3/8" insulation from the end of the cable and twist the exposed end to avoid fraying.

3. Press on a "push-pin" terminal to reveal an eye into which the twisted cable is inserted; release the terminal to lock.
