Connecting block for use with impedance matching volume controls
Our take on the Russound EZB-1SC by Crutchfield's Marshall Chase
This Russound connecting block lets you easily and neatly attach up to four pairs of speakers with impedance matching volume controls to a single stereo amplifier or receiver perfect for multi-room audio applications. For wiring up to eight pairs of speakers to your stereo amp or receiver, add Russound's EZB-2SC expansion block.
The EZ-BLOCKS are designed for surface mount applications. Position them in an area close to the amplifier and volume control wiring. Secure each block to the mounting surface with four #8 x 1/2" screws (not included).
Custom-tailored advice before and after you buy
Installing this modular block requires you to use impedance matching controls and to run speaker cable in your walls, unless your home is already pre-wired. Our Audio/Video Designers can help you map out the details. Plus, our tech support specialists can help you through your installation step-by-step.
Easy to install and works as advertised.

Power requirements are dependent on speaker efficiency and room size. [ Bryan Jan 06, 2014 ]
IF all four are on at once at the same loudness you would need four times the power. But the way you hook them up will affect the impedance which will affect the available power. Also some amps are designed to run two pairs in series which produces a higher impedance. To be on the safe side get an amp that is guaranteed to handle impedances down to 4 ohms. Those amps tend to be the better ones and a bit more expensive. And get your salesman's advice on how best to hook them up. [ PETER Jan 05, 2014 ]
