2. KBLFunctions

Use the Select switch to choose between the various source (playback) components for listening. Be sure to lower the volume when switching among components, as large differences in level between sources can cause damage to other components.

The Select switch is also used to choose the signal to be sent to the tape recorders via the Record outputs.

Whentwo KBLsare used in dual-mono, both Select switches must be set the same.

There is a Mute function at the 12 o'clock position that should be used when source material is being changed, or when source components are being turned on and off, and at the completion of each listening session.

Note: Componentsthat are not being listened to should be turned off or have their volume turned down. For instance, a tuner should be turned off, or have its volumelowered while it is not being listened to.

b. Monitor

Use the Monitor switch to listen to the playback from a recording device. This can be done while the recording is in process, such as with three-

head tape recorder, or during playback only.

The inputs available on the Monitor switch are S-1 and B-2. These are wired in parallel to the same inputs on the Select switch.
