INPUT 1
Microphone/Telephone Input
Input 1 can be Microphone Input or a Telephone Paging Input by
means of a rear panel selector.
MICROPHONE INPUT = Impedance is 250 ohm balanced.
Terminal Strip Derivation.
TELEPHONE PAGING INPUT = Impedance is 600 ohm,
Transformer balanced. Terminal Strip Derivation.
INPUT 2
Microphone/Satellite Receiver/Program Input
Input 2 can be Microphone Input, Satellite Receiver Input or
Program Input by means of a rear panel selector.
MICROPHONE INPUT = Impedance is 250 ohm balanced.
Terminal Strip Derivation.
SATELLITE RECEIVER INPUT = Impedance is 10K ohm bal-
anced. Terminal Strip Derivation.
PROGRAM INPUT = Impedance is 10K ohm unbalanced. Stereo
Summing is provided. Dual Phono Jacks derivation.
INPUT 3
Auxiliary/CD Input
Input 3 can be AUX or CD Input by means of a rear panel selector.
AUX/CD INPUT = Impedance is 47K ohm unbalanced. Stereo
Summing is provided. Dual Phono Jacks derivation.
INPUT 1 VOX - INPUT 2 VOX
Addressable Dual Vox System - The Dual VOX System
can be individually selected to operate independently with
Input 1 and Input 2 by means of rear panel switches.
INPUT 1 - VOX Switch On-Off
INPUT 2 - VOX Switch On-Off
DIRECT MUTING - The Direct Muting will always mute
Input 3 when activated by contact closure. Input 2 can be
selectively muted if the Input 2 Mute Switch is in the ON
position.
ZONE 1 AND 2 SOURCE SELECTOR
Selector Switches select Source for ZONE 1 Output (600
ohm, 1 Volt or 8 ohm, 1 Watt) and for ZONE 2 Output (8
ohm, 1 Watt).
ZONE 1 SWITCH = Selects Source from either Input 2 or Input
3.
ZONE 2 SWITCH = Selects Source from either Input 2 or Input
3.
EQ LINK ON-OFF SWITCH
This Switch interrupts (ON Position) continuity between the
Preamplifier Section Output and the Power Amplifier
Section Input of the Amplifier to allow the inser tion of an
External Acoustic Equalizer. When the Switch is in the OFF
Position the MIX BUSS is active.
