Load Impedance: Safe with all types of loads.
Xs500, 700, 900, 1200: 2 to 8 ohms in Stereo, 4 to 8 ohms in Bridge Mono.
Xs4300: 4 to 8 ohms in Stereo, 8 ohms in Bridge Mono.
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: 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 (Channels 1 and
2, Channels 3 and 4 in Xs 4300). 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) balanced, unbalanced: 20 k ohms, 10 k ohms.
Output Connectors:
Balanced XLR connectors (2-channel models only): One per channel, 3-pin male XLR
connector in parallel with XLR-1/4" 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 (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 or four-channel (Xs4300 only)
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 17.14-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)
Crown's Three Year, Full, No-Fault Warranty
Crown offers a Three Year, Full, No-Fault 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 intentional abuse. And the coverage is transferable
should you sell your amplifier.
