RDL Universal
Audio Mixer
Use in any application
requiring mixing
of two audio sources.
A mic may be mixed
with a line level music
source. Two mics may be mixed to feed the mic or line
level input of a power amplifier. A mic or professional
+4dBu line level mono sum is possible. It may be used
to convert mono line level signals from consumer to
professional, or from professional to consumer format.
It may also be used as a microphone preamplifier, or
conversely to adapt unbalanced or balanced line level
signals into the microphone input of other equipment.
Unit requires a 24~33VDC, 60mA ground referenced
power supply.

555-ST-MX2 $117.00
RDL Line Level
Mixing Amplifier
Three channel audio
mixer combines up to
three line level signals
to a single line level
output. The input
circuit accepts either balanced or unbalanced signals,
either high or low impedance. The output is capable of
driving high or low impedance, balanced or unbalanced
loads. Gain on each input channel is individually
adjustable from –14~+24dB. Outputs from multiple
units may be connected in parallel to form a multi
channel mixer. Power requirements: 24~30VDC
floating or 12~15VDC bipolar supply, 55mA.

RDL Six–Watt
Utility Amplifier
Compact single–channel
amplifier features two
balanced audio inputs,
with adjustable gain, and
delivers 6W RMS to an
8ohm load. Since each input is mixed equally, it is perfect
for monitoring a stereo line from a single speaker. Built–in
equalization circuit provides adjustable 0~5dB gain at
60Hz, for enhanced low frequency response. The output
stage features auto resetting short–circuit and thermal
overload protection. Specifications: •Frequency response:
35Hz~20KHz •THD: 0.35% •Input: 10Kohm, 400mV
(line level) •Power requirements: 24~33VDC, 350mA,
ground referenced

555-ST-PA6 $84.49
RDL SPDIF
Repeater/Amplifier
Use where SPDIF signal levels
need to be boosted or recovered,
or where a digital audio signal
needs to be converted between
coaxial and optical. Single
channel module features
BNC, phono and optical inputs
(conventional SPDIF format), any one of which may be
used, and the coaxial input has priority over the optical
input. BNC, phono and optical outputs are provided.
Either of the coaxial jacks, and/or the optical output
may be connected simultaneously. High input sensitivity
permits operation with coaxial input levels as low as
100mV. The module detects and amplifies low signals,
and reshapes the output for minimum jitter. Installation at
the receiving end of a weak SPDIF line restores the signal
level to its correct amplitude, and extends the useful range
to avoid signal dropouts. Front panel LED illuminates
when sufficient input signal is received to produce the
correct output from the module. Requires 24VDC,
80mA, ground referenced.

RDL Balanced to
Unbalanced Convertor
Device features two identical
active (transformerless)
channels that accept balanced
input, via XLR female connectors, and provide
unbalanced outputs, via RCA type female connectors.
They are perfect for integrating commercial sound and
high–end home theater equipment in the same system.
Individual gain trim adjustments are provided for each
channel. Specifications: •Frequency response:
10Hz~40KHz •THD: <0.005% •Power requirement:
24VDC, 50mA, ground referenced

RDL Unbalanced to
Balanced Convertor
Device features two identical
active (transformerless)
channels that accept unbalanced
input, via RCA type female
connectors, and provide
balanced outputs, via XLR male connectors. They are
perfect for integrating commercial sound and high–end
home theater equipment in the same system. Individual
gain trim adjustments are provided for each channel.
Specifications: •Frequency response: 20Hz~40KHz
•THD: <0.05% •Power requirement: 24VDC, 50mA,

RDL Stereo
Automatic Level
Control
Ideal in applications
where consistent
audio level is needed
from stereo sources
with varying output, such as multiple CD changers,
satellite or broadcast television receivers. It maintains
consistent –10dBv output for input signal variations as
great as 25dB. Because the mid and high band audio
frequencies are controlled separately, the level pumping
effect, often associated with automatic gain and
compression, is minimized. The AGC and compression
attack release times adjust according to the program
material to further reduce any audible effects of the
module. Additionally, when audio levels fall, and remain
below a level appropriate to that source, the module stops
increasing the gain. As audio levels fade out, the module
tracks the level for a natural sound. These features
combine to produce nearly inaudible adjustment yet
consistent levels without the listener fatigue associated
heavily compressed music dynamics. Input and outputs
are line level, 10Kohm unbalanced. All connections
are RCA type female. Requires 24VDC, 80mA,
ground referenced.

RDL Audio
Distribution
Amplifier
Use in applications
requiring stereo audio distribution with four outputs, or
mono distribution with eight outputs. This unit provides
multiple, isolated audio feeds, individual line level
controls, audio presence indicators and gain from
–15~+18dB. Input and output connections are made
via a full size screw terminal strip, on the rear panel, and
accept any combination of balanced or unbalanced wiring
configurations. Gain for each channel is individually
adjusted via a front–panel screwdriver gain control.
