Aural Exciter
Circuit adds presence and intelligibility to vocals
when paging. The dual function 10 band equalizer
can be used for feedback control or acoustic 
shaping, providing ±12dB of boost or cut from
62.5Hz~16KHz in acoustic mode and from
125Hz~8KHz in feedback control mode. Other 
features include automatic level control, automatic
muting with a VOX circuit, and a variable mute
level. Inputs: Six Lo-Z balanced microphone, 2 Hi-Z
auxiliary sources and a telephone paging input (Mic
5 is switch-selected for mic or telephone line; Mic 6 
is switch-selected for microphone or Aux 1). Mics 1

Wall Mount FM Tuner
Economical wall mount FM radio/receiver is
designed to provide background music over a
PA system, or music-on-hold to a telephone 
system. Includes 1W and line-level outputs 
to facilitate compatibility with a variety of 
paging/telephone systems. Built–in speaker
makes tuning easy. LED indicator illuminates
when the signal is strongest, and AFC prevents
signal drift. Tone and
output volume controls
are screwdriver
adjustable. Screw 
terminals are provided
for outputs, antenna
and 24V power 
source. Also 
has attached 
telescopic antenna.

Matching Audio
Transformer
General purpose matching
transformer allows proper
connection between high and
low impedance inputs and
outputs. Bi–directional device may be
used to balance an unbalanced line, or
provide isolation between two pieces of
equipment. It may also be used to produce
a balanced mic level signal from a line
level source such as a CD, DVD or tape
player, or computer sound card. Primary:
10Kohm, RCA type male connector.
Secondary: 600ohm center tapped, with screw
terminals. Steel enclosure measures 2

Voice 
Activated Relay
This device monitors audio activity over a wide
range of input voltages and operates a DPDT relay.
It may be used to detect voltages as low as that
directly from a microphone, or as high as from a 70V
speaker system. Inputs include: Mic level, 600ohm
line level, 25V and 70V distributed speaker level. A
low level, transformer isolated, 600ohm output is
also made available for use with other equipment, 
allowing this to be used as a balanced, low 
impedance microphone preamp. Features:
•Adjustable trigger threshold •Adjustable mic 
preamp gain •Adjustable 0.25~20 second release
delay •Relay status LED •All input and output 
connections are screw terminal •Requires
12~24VDC, 100mA, power supply sold separately

Signaling Tone
Generator
Multiple tone
generator is
designed to 
generate four 
distinct signals;
pulsed tone, slow
whoop, repeating
chime and steady tone. It is an excellent source for
alarm or pre-announce signals in public address or
telephone paging systems. Each of the four signals
may be applied continuously (until interrupted), or
limited to a double-burst (except for the steady tone)
for pre-announce applications. Signals are triggered
by an external device providing a contact closure.
Output level and pitch control are adjustable.
Accepts Hi-Z input from a program source such 
as a tuner, turntable, cassette player, etc., and 
will maintain precedence over the program material
for the duration of the contact closure. Requires
12~48VDC, 26mA, adaptor (PRS-40C) available 
separately. All input and output connections are
screw terminals. Dimensions: 6
