600 ohms, mic level, pin-2 hot
PAD:
-15dB
Power:
48V Phantom
FEATURES AND FUNCTIONS
INPUT -
jack connects to instruments
like guitars and keyboards.
-15dB PAD
- reduces the input level
by 15dB to prevent overload from high
output devices like CD players and
active pickups.
LED INDICATOR -
lights to confirm
phantom power is active and the Pro48
is working.
THRU -
jack passes the instrument
signal to the on-stage amplifier.
FULL BOTTOM FOOT -
neoprene
foam foot provides electrical isolation
and plenty of friction to stay put.
14 GAUGE STEEL -
bookend shell
creates a protective zone around the
switches and connectors.
OUTPUT -
600
Ω
balanced mic-level
output (pin-2 hot) drives long cables for
runs to 1000 feet without appreciable
loss.
GROUND LIFT -
helps to reduce hum
and buzz caused by ground loops.
SWITCHING POWER SUPPLY -
steps
up the current from phantom power to
produce 9 volt internal rails. With more
voltage to work with than typical active
DIs, the Pro48 exhibits more headroom
and dynamic range while lowering
noise.
MILITARY-GRADE -
double-sided PCB
is bolted to steel standoffs for road-tough
construction.
ISOLATED CONNECTORS -
are 100%
electrically isolated from the chassis.
ACTIVE DRIVE CIRCUIT -
electronically
balances the signal and converts it to
low-Z mic-level.
I-BEAM DESIGN -
inner steel enclosure
is made extremely rigid with an I-beam
profile. This eliminates stress that could
torque the PC board and cause solder
joint failure.
