without risk of damage to the preamplifier, amplifier(s) or speakers. Its
setting is a matter of personal taste.

2. KBL Functions
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.
When two KBLs are 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: Components that 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 volume lowered 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.
