FEATURES AND FUNCTIONS

INPUT - jack connects to instruments
1
like guitars and keyboards.
-15dB PAD - reduces the input level
2
by 15dB to prevent overload from
high output devices.
LED INDICATOR - lights to confi rm
3
phantom power is active and the
Pro48 is working.
THRU - jack passes the instrument
4
signal to the on-stage amplifi er.
FULL BOTTOM FOOT - neoprene
5
foam foot provides electrical isolation
and plenty of friction to stay put.
14 GAUGE STEEL - bookend shell
6
creates a protective zone around the
switches and connectors.
OUTPUT -
7
output drives long cables without
appreciable loss.
GROUND LIFT - helps to reduce hum
8
and buzz caused by ground loops.
SWITCHING POWER SUPPLY -
9
steps up the current from phantom
power to produce 9 volt internal rails.
With more voltage to work with than
typical active DI's, the Pro48 exhibits
more headroom and dynamic range
while lowering noise.
MILITARY-GRADE - double-sided
10
PCB is bolted to steel standoff s for
road-tough construction.
ISOLATED CONNECTORS - are
11
100% electrically isolated from the
chassis.
A C T I V E D R I V E C I R C U I T -
12
electronically balances the signal
and converts it to low-Z mic-level.
I-BEAM DESIGN - inner steel
13
enclosure is made extremely rigid
with an I-beam profi le. This eliminates
stress that could torque the PC board
and cause solder joint failure.
