Specifications
Size: 19”W x 18”D x 5.2” (3RU) H, including projecting
controls and parts. Budget 5 RU for proper ventilation and
heat dissipation, with 1 RU above and below the enclosure.
Exceptions being other equipment housed in shallow enclosures
that will not block the compressor’s ventilation slots.
Weight: 37 lbs, not including rack brace kit. Kit requires 1
RU of vertical clearance, which makes good use of the
ventilation spacing required by the unit, and must be
installed if the compressor is to be used in a mobile or
transportable production application.
Mains requirements: 120 VAC, 60~, 130 Watts warm-up interval,
100 Watts during operation.
Warm-up delay: Approximately 30 seconds from cold start to
COMP relay engagement (green comp lamp is lit). Note that
about 5 minutes of additional warm-up time is recommended to
permit the tubes to reach thermal equilibrium before use
begins.
Fuse Complement (120 VAC): 5x20 mm 1.6 A, 250 V SLO-BLO for
the mains, 5x20 mm 0.125 A, 250 VAC standard speed for B+.
220-240 VAC: Use 5x20 mm 0.8A SLO-BLO for the mains fuse.
Maximum PROGRAM input signal level, PROGRAM XLR input: +32
dBu, or 30 Vrms, 87 Vp-p.
PROGRAM input impedance: XLR= 35 k-ohm bridging balanced, TRS
= 18 k-ohm bridging balanced. Always ground the ¼ inch plug’s
RING to SLEEVE when feeding UNbalanced signals into the
PROGRAM input TRS jack.
Maximum PROGRAM output signal level, PROGRAM XLR output: +34
dBu, or 38 Vrms, 109 Vp-p across 600 ohms (2.5 watts), add
about 5 dB for 10k-ohm loads (Caution! High voltage!).
Subtract 6 dB (50%) for the PROGRAM TRS output jack.
PROGRAM output impedance: XLR = 600 ohm balanced floating
transformer coil, TRS = 150 ohm balanced floating transformer
coil. Always ground the ¼ inch plug’s RING to SLEEVE when
converting BALanced signals from the TRS jack into UNbalanced
signals.
