power the amplifier.
7. Speaker Outputs
Output terminals for connection to either 70V,
25V, or low-impedance speaker types.
8. Input 1- Balanced LINE/MIC
Input 1 will provide an electronically-balanced
input with selectable gain suitable for line-
level signals, including dry loop telephone
signals as well as balanced low-impedance
microphones. The associated slide switch sets the

when active.
9. Mute Send
The ability of Input 1 to mute Input 2 can be
enabled or disabled using this switch.
10. Input 2 - Unbalanced AUX
Provides a high-impedance input through a
set of stereo combining RCA jacks. This input
is muted by Input 1 when muting is enabled.
11. REC Output
These RCA connectors provide a signal-level
output of the program material provided to the
speaker.
12. AC Mains
AC mains voltage will be provided through an
IEC connector with fuse holder and detachable
3-conductor IEC cord. The nominal line voltage
is 120V AC, 60 Hz.
