Additionally, you can connect two different stereo receivers to the SVL-4AB by using its A and B amplifier inputs. You don't have to worry about overloading either amplifier.
P E A K E R E L E C T I O N Features and Benefits The SVL-4AB offers a number of improvements over other speaker selector/volume controllers: Amplifier A/B Switching—The SVL-4AB provides amplifier switching for each pair of speakers. The switches are “break-before-make“...

SVL-4AB. 100% tested, electronically and acoustically, for frequency response, distortion and power handling. Standard 17" width allows the SVL-4AB to stack neatly with other standard size components. May be used with 4, 6, or 8-ohm speaker systems.
E L E C T I O N Installation Considerations SVL-4AB Power Handling The SVL-4AB is designed for use with receivers or amplifiers having a maximum power output of 100 watts per channel at 8 ohms. Damage caused by the use of higher-power receivers or amplifiers will void the warranty.

The actual impedance load the SVL-4AB presents to each of your receivers or amplifiers will vary, depending on how many speaker pairs are playing, and the impedance rating of each speaker.

Using the SVL-4AB with Tube-Type Amplifiers Virtually all tube amplifiers must have a load connected at all times. If one of the amplifiers to be connected to the SVL-4AB is a tube amplifier, be sure to always have at least one pair of speakers switched on at all times.

3. Make the connections to the SVL-4AB. The amplifier/speaker connectors on the SVL-4AB are removable. If you wish, you may remove the SVL-4AB's connectors to facilitate installation [see (Figure 3)]. Strip 3/8" of insulation from the end of each wire. Tightly twist the end of each wire until there are no frayed ends.
P E A K E R E L E C T I O N Operation The are two ways to use the SVL-4AB. You may play and "TECH TIP" adjust the volume of one pair of speakers at a time, or play multiple pairs simultaneously.

1. Make sure both of the amplifiers are OFF and set the vol- ume controls to minimum. 2. On the right side of the SVL-4AB's front panel is a button labeled PROTECTION. This button activates the SVL-4AB's impedance correction circuitry. The circuitry assures that both of your receivers or amplifiers will see a safe operating load when playing multiple speaker pairs simultaneously.

8. Using the appropriate volume controls on the front of the SVL-4AB, adjust the volume of the speakers to the desired lis- tening level. The volume control of your receiver or amplifier acts as the master volume for all of your speaker pairs.
A/B button. Constant Protection Switches The SVL-4AB is equipped with rear panel overrides of the protection circuits that enables you to maintain constant impedance protection regardless of the position of the front panel switch.
