Specifications
Specifications are for the basic signal paths, per
channel, with 600 ohm loads connected to the ana-
log program outputs in a fully loaded RMX
digital
28-input slot mainframe.
0 dBu equals 0.775 volts RMS regardless of cir-
cuit impedance, which equals 0 dBm into a 600
ohm circuit. Noise specs based on 22 kHz mea-
surement bandwidth. A 30 kHz bandwidth mea-
surement increases noise by about 1.7 dB.
Total Harmonic Distortion (THD+N) is mea-
sured at a +18 dBu output, using a swept signal
and a 22 kHz low pass filter.
FSD = Full Scale Digital, +24 dBu

Send can be set for 44.1 kHz)
Processing Resolution:

The RMX
d8-HL has a built-in 48-volt supply. All
are supplied with a 110 VAC IEC input cord.
Two keyed 48-volt power cables are supplied
with the console mainframe Installation Kit so that
a second PRE99-1205 supply (optional) can eas-
ily be added for redundant supply operation. The
mainframe and the RMX
d8-HL include an inte-
gral power coupler so a second redundant supply
can be connected.
The power supply (and the RMX
d8-HL) has a
recessed front panel On/Off switch along with a
green LED that indicates the +48 volt output is
good.
The power supply is designed for continuous
24/7 operation and is fully regulated and protected
against excessive current by internal fuses and elec-
tronic safeguards.
