The PAA-60 is designed to cover a nearly
unlimited range of audio amplifier or interface
applications.
As a basic distribution amplifier, the PAA-60 may
be used as a 1X8 MONO DA or a 1X4 STEREO
DA. An easily accessible DIP switch quickly
conforms the PAA-60 to your applications. The
PAA-60 can interface unbalanced sources to
balanced feeds. When used in this mode, the
differential input prevents ground loops from
causing interference. Both channels have gain-up
switches to accommodate -10 dBm inputs. The
PAA-60 can also interface +4 dBm balanced to
!10dBm unbalanced.
A unique feature of this unit is the signal metering
LEDs. Each channel has an LED which indicates
a signal presence greater than -30dBm with a
green glow. When a program level greater than 20dBm is present, the LED glows orange. If the
signal reaches clipping levels either internally or on
the output, the PAA-60 warns with a bright cherry
red indication. When there is no signal present, the
LEDs provide power on indication by flashing
green once. They flash red once for power off.
The gain controls for each channel may be
adjusted from gain pots center at 0dB. The gain controls are
supplied with miniature knobs.
The PAA-60 requires 20-30VAC or +25-35VDC.
The PAA-60 portable DA will operate at reduced
specifications with a power input as low as ~ 10
volts DC.
Just a few of the PAA-60's problem solving
capabilities ...
> Two channel mixer with simple LED metering.
> Visual audio presence monitor (The PAA-60
produces sufficient output to drive headsets or ear
pieces)
> Adjustable Intercom IFB amp with local (talent)
control and talent alert (clip indication)
> MONO DA with two separately adjustable feeds
> The PAA-60 should be compatible with most
intercom system specifications for power and level
requirements.
