You Need The RU-MX5!
The RU-MX5 is part of the group of RACK-UP products from Radio Design Labs. RACK-UPs feature the
advanced circuitry for which RDL products are known, combined with accessible user-friendly controls and
displays. The ultra compact design permits high-density installations, with three products mounted in a
single rack unit! Single RACK-UPs can be mounted right where they are needed using the adhesive
method popularized by RDL's STICK-ON
RACK-UP module above, below, or in front of any flat surface!
APPLICATION: The RU-MX5 is the ideal choice in many applications where a combination of mic and/or
line level signals need to be mixed. All connections are made using full-size barrier block terminals on the
rear panel.
Four of the RU-MX5 inputs can accept either mic or line level inputs. The fifth input is for line level only.
Mic inputs are designed for low-impedance balanced microphones, though high-impedance unbalanced
mics can be connected as well. Jumpering a rear-panel terminal can selectively connect an internally
provided 24 Vdc phantom voltage to any, or all, of the mic inputs. All line-level inputs permit the
connection of either balanced or unbalanced, high or low impedance audio lines.
A separate unbalanced MIX input allows an external audio source to be summed directly into the mix
amplifier, bypassing the front-panel level controls. This feature can be used to cascade multiple mixers to
expand system capabilities.
The RU-MX5 provides two balanced outputs, one at mic level and the other at line level. Either of these
outputs may be unbalanced if required. Both outputs may be used at the same time.
Audio levels are adjustable on the front panel. A convenient write-on label area is provided above each
fader knob.
Three LED indicators provide output level metering. Audio presence is indicated by the -20 indicator. 0 dB
shows usual audio levels, and a +5 dB LED displays audio peaks. The metering section is peak-reading
and refers 0 dB to a balanced audio output of +4 dBu.
Wherever a mixer is needed to provide superior audio clarity, user adjustments, reliability, compactness
and unsurpassed versatility, the RU-MX5 is the ideal choice. Use the RU-RA3 rack-mount adapter to
mount multiple mixers, or to combine related products (such as audio or video distribution, or audio
metering) into a single rack unit!
