PORTABLE AUDIO DISTRIBUTION AMP
MODEL PAA-60
FEATURES
1 input, 8 outputs
Select Dual 1 X 4
Differential Input
Stereo Operation
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
signalreachesclippinglevelseitherinternallyoron
the output, the PAA-60 warns with a bright cherry
redindication.Whenthereisnosignalpresent,the
LEDs provide power on indication by flashing
green once. They flash red once for power off.
Balance/Unbalance Match
Gain Control Both Channels
Level Indication
Mono Operation
The gain controls for each channel may be
adjusted from -4to +9dB (+24dBm with gain). The
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
intercomsystemspecificationsforpowerandlevel
requirements.
