Load Impedance: Safe with all types of loads.
Rated for 2 to 8 ohms per channel in Stereo, 4 to
8 ohms in Bridge Mono.
DC Output Offset (shorted input): < ±75 millivolts.
AC Line Voltage and Frequency Configurations
Available (±10%): 120VAC/60 Hz and 230VAC/50 Hz.
Front Panel Controls
Level: Two or four front-panel, gray rotary level
controls, one for each channel.
Power Switch: On when in the right-hand position.
Front Panel Indicators
Signal: Two or four green LEDs, one for each
channel, illuminates when the channel’s input sig-
nal level is above –40 dBu.
Clip: Two or four front-panel red LEDs, one for
each channel, illuminates when the channel’s out-
put signal is being overdriven.
Power: Yellow LED indicates amplifier has been
turned on and AC power is available.
AC Mains: Red LED indicates the presence of AC
power at the power cord, even if the amplifier is not
turned on.
Fault: Red LED illuminates when amplifier is in
protect mode. Also illuminates briefly during nor-
mal power-up when amplifier is first switched on.
Bridge: Yellow LED indicates that amplifier is in
Bridge-Mono mode
Temp: Red LED indicates that channel(s) are in
thermal protect mode.
Input Connectors
XLR-1/4 inch combo connectors: One per chan-
nel, 3-pin female XLR connector and TRS-1/4 inch
phone jack accept balanced or unbalanced signals.
3-pin Phoenix-style connectors (2-channel mod-
els only): One per channel, accepts balanced or
unbalanced signals
Output Connectors
Balanced XLR connectors (2-channel models
only): One per channel, 3-pin male XLR connector
in parallel with XLR-1/4 inch combo and Phoenix-
style input connectors for daisy-chain operation.
5-way binding post output connectors: One pair
per channel; accept banana plugs, spade lugs or
bare wire. Note: Binding post outputs on European
models come with safety plugs installed to prevent
European power-cord plugs from being inserted. The
top & bottom entry positions for these connectors
should therefore be used with European models.
4-pole Speakon output connector: One connector
per channel. Accepts a 4-pole Speakon connector.
Protection
Xs Series amplifiers provide extensive protection
and diagnostic capabilities, including output current
limiting, microprocessor-controlled DC protection,
circuit breaker, and special thermal protection for
the unit’s transformers.
Cooling
Flow-through ventilation from front to back.
Internal heat sinks with forced-air cooling for rapid,
uniform heat dissipation.
Dimensions
EIA Standard 19-inch (48.3-cm) rack mount width
(EIA RS-310-B), 3.5-inch (8.9-cm) height and
17.14-inch (43.5-cm) depth behind the mounting
surface.
Weight
Net Weight: 28 lb 14 oz (13.1 kg).
Shipping Weight: 34 lb (15.4 kg)
Regulatory Certifications
Other Applications
Note: Specifications apply to units in Stereo mode
with 8-ohm loads and rated input sensitivity unless
otherwise specified.
T
he Xs Series of power amplifiers from Crown represents a new era in
affordable, quality switch-mode power amplification. The line consists of
four models in a uniform, rugged 2U chassis, incorporating the best of tried-
and-true design principles and innovative features. The series features four
2-channel models: the Xs500, Xs700, Xs900 and Xs1200. Each has identi-
cal features, except for output power. Xs Series amplifiers are professional
stereo power amplifiers engineered to meet demanding audio require-
ments—reliably and within budget.
