Crown's Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown amplifier—
an unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown
amplifier is warranted to meet or exceed original specifications for the first three years of
ownership. During this time, if your amplifier fails, or does not perform to original specifications,
it will be repaired or replaced at our expense. About the only things not covered by this warranty
are those losses normally covered by insurance and those caused by intentional abuse. And the
coverage is transferable, should you sell your amplifier.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside of the
USA, please contact your authorized Crown distributor for warranty information or call 574-294-8200.
AC Line Voltage and Frequency Configurations
Available (±10%): 120VAC/60 Hz and 230VAC/50 Hz.
Controls
Level: Two or four front-panel, gray rotary level
controls, one for each channel.
Power On: Front-panel switch; on when in the right-
hand position.
Indicators
Signal: Two or four green LEDs, one for each
channel, illuminates when the channel's input signal
level is above –40 dBu.
Clip: Two or four front-panel red LEDs, one for each
channel, illuminates when the channel's output
signal is being overdriven.
Power: Yellow front-panel LED indicates amplifier
has been turned on and AC power is available.
AC Mains: Red front-panel LED indicates the
presence of AC power at the power cord, even if the
amplifier is not turned on.
Fault: Red front-panel LED illuminates when
amplifier is in protect mode. Also illuminates briefly
during normal power-up when amplifier is first
switched on.
Bridge: Yellow LED indicates that amplifier is in
bridge mode.
Temp: Red LED indicates that channel(s) are in
thermal protect mode.

Input/Output

Input Connectors
XLR-1/4" combo connectors: One per channel,
3-pin female XLR connector and TRS 1/4" phone
jack accept balanced or unbalanced signals.
3-pin Phoenix-style connectors (2-channel models
only): One per channel, accepts balanced or
unbalanced signals.
Input Impedance (nominal): 20 k ohms balanced,
10 k ohms unbalanced.
Output Connectors
Balanced XLR connectors (2-channel models only):
One per channel, 3-pin male XLR connector in parallel
with XLR-1/4" 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 (2-channel
models only): One connector per channel. Accepts a
4-pole Speakon connector.
DC Output Offset (shorted input): ±75 millivolts.
Output Signal: Stereo, unbalanced, two-channel.
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.

Construction

Ventilation: Flow-through ventilation from front to back.
Cooling: Internal heat sinks with forced-air cooling
for rapid, uniform heat dissipation.
Air Volume Requirements (per minute per unit):
80.15 ft³ (2.27 m³).
Dimensions: EIA Standard 19 inch (48.3 cm) rack
mount width (EIA RS-310-B), 3.5 inch (8.9 cm)
height and 17.135 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).
