RDL Application Specific Audio Modules
Radio Design Labs is known, throughout the commercial sound industry, for
innovative, low cost, flexible solutions to difficult audio challenges. Their application
specific modules provide easy control, filtering, switching and distribution of audio
signals, in permanently installed systems. The ultra–compact Stick–OnSeries
(ST) features a durable bottom adhesive pad, for quick, permanent mounting nearly
anywhere. High quality screw terminal strips accept 14~30AWG wire. The compact
Rack-Up Series (RU) feature accessible user–friendly controls and displays, with
the ability to mount up to three units in a single rack space. The Flat–Pak Series
(FP) feature durable, all metal cases that may be directly screwed or bolted to
cabinets or shelves. All controls and connections are top mounted, allowing close
placement of multiple modules. All Flat–Pak modules are supplied with a power
interconnect cable for daisy-chaining multiple modules from a single power supply. Detailed description,
specification and application sheets are available on request.

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.

555-FP-ALC2 $225.00 $202.50
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.

Output Line
Amplifier
Many audio
products provide
optimum
performance
when feeding a bridging input, but may not provide
output needed to directly drive low impedance lines
terminated with 600ohm transformers. Specifically
designed for such installations, this is also ideal
when high gain line level audio transmission
is required. Audio inputs are bridged at 5Kohm
and gain is adjustable from unity to +24dB via a
precision 25–turn potentiometer. Outputs are
designed to drive long balanced audio lines into
600ohm loads. Audio circuits DC coupled for
the ultimate in pure, transparent audio clarity.
Input and output circuits function as electronic
transformers, permitting either balanced or
unbalanced connection. Typical applications:
•Conversion from balanced to unbalanced
•Conversion from high to low impedance •Power
requirements: 24~30VDC floating or 12~15VDC
