Specifications

Features

Construction: The chassis is component-sized (17" wide) and made from durable black metal with padded feet.

Speaker Switches: Each set of speaker outputs has an on/off switch so any combination of connected speakers can be played at any given time.

Protection Switch: The impedance protection switch on the front of the unit safeguards the receiver or amplifier even when all 4 pairs of speakers are playing (4 pairs of 8-ohm speakers will present a 4.5-ohm load to the receiver or amplifier).

Note: You will need to activate the "Protection" switch whenever the overall system impedance might fall below 4 ohms. It is recommended to verify that the receiver or amplifier is capable of driving a 4-ohm load.

Constant Protection: This speaker selector is equipped with a manual override for the protection circuit that enables you to defeat the front panel protection switch and maintain constant impedance protection. This will safeguard your amplifier from being overdriven due to accidental or improper use.

Removable Speaker Terminals: There are four removable speaker output terminal blocks and one removable speaker input terminal block. These connectors make it easier to wire the speakers to the selector. Each terminal block can accommodate up to 12 gauge wire.

Labels: Included are 72 pre printed and 6 blank label stickers for easy identification of the front panel controls.

Specifications

Specifications:

  • Frequency Response: 20Hz-20kHz +0dB, -0dB (flat)
  • Power Handling: 250 watts per channel RMS at 8 ohms

Customer Q&A

Q
If I hook up 2 pair of 6-ohm in-ceiling speakers to this unit what load will the receiver see if I run all 4 speakers at the same time?

A
2 pairs of 6 ohm speakers in parallel would cause the receiver to see a 3 ohm load. You could wire up the 2 pairs of 6 ohm speakers in series which would allow the receiver to see a 12 ohm load. The only drawback would be that the receiver's final output volume will be slightly reduced.

I am unsure of the exact impedance. However, it is recommended that you use the "Protection" button in that set up to ensure that your receiver doesn't see below a 4-ohm load. You should also, ensure that your receiver can handle a 4-ohm load.
