Inputs 1 - 3 - Inputs 1 is set as Microphone Input Impedance is 250
ohm balanced. Input 2-4 can be set as MIC Inputs or switched to
AUX 1 and AUX 2 respectively (internal switch). Impedance is 47 K
ohm.

Phantom Power - Phantom Power is provided on all Inputs set as
Microphone.

Stereo Summing - Two separate RCA Jacks are provided
for Input 3 and 4 (Left and Right). A Stereo signal connected
to either Input is buffered and internally summed to
Mono.

Input 3 & 4 Attenuators - When the Inputs are set as AUX 1 and
AUX 2 the input sensitivity may be varied by a rear panel Variable
Attenuator. This feature allows to set the output level of Programs
originating from different sources (CD, Satellite Receiver, etc.).

Phone Paging - A separate input is provided to interface with a
Phone System. Input Impedance is 600 ohm, Transformer
Balanced. A level control is available on the front panel.

Module Port - Por t accepts standard plug-in module.
Module Level Control is provided on the front panel. See list
of modules available from PASO.

MIX BUSS - This Input/Output may be utilized to parallel two
amplifiers or as an input for a Microphone Mixer or other
audio source. When used as an Input the Amplifier Level and
Equalization Controls have no effect.

Line Out - 600 ohm, 1.5 Volt Line Output.

Remote Volume Control - The AUX 1 Input Volume may
be adjusted from a remote location. The Remote Volume
Input utilizes a 10K Pot and is immune to Audio Interference
(DC Operation).

Addressable Dual VOX System - The Dual VOX System can
be individually selected to operate independently on all
Inputs by means of jumpers . Any Input may be set to activate
either VOX 1 or VOX 2.

Addressable Dual Muting System - The Dual VOX System
can be individually selected to operate independently with
all Inputs by means of jumpers . Any Input may be set to
activate either MUTE 1 or MUTE 2.

MUTE 2 Adjustable Delay - A rear panel control adjusts the
MUTE 2 Time Delay (the time the MUTE 2 stays activated)
from 3 Sec. to 60 Sec. Particularly useful to control the
length of time that an Input mutes another (for example AUX
1 over AUX 2).

Music on Hold - Output Channel 1 - Channel 1 provides a
1 Volt, 600 ohm balanced output and a 2 Watt, 8 ohm output
for Music/Message on Hold or Zone 1 Speaker Output.
Internal Jumper selects the source from either AUX 1, AUX
2 or Input Module. Level Control is provided.

Output Channel 2 - Channel 2 provides a 2 Watt, 8 ohm
output for Zone 2 Speaker Output. Internal Jumper selects
the source from either AUX 1, AUX 2 or Input Module. Level
Control is provided.

EQ LINK - EQ Link (Preamp Out) (Power Amp In) jacks are
provided for External Equalizer. Activated by the EQ Link
Switch.

Tone By-Pass Switch - The Tone by-pass switch defeats
the setting of the Treble and Bass Controls. Should be used
when an External Equalizer is utilized.

24 VDC Supply Output - A 24 Volt DC, 250 mA regulated
Power Supply is provided for external accessories
