T
T
he LPS Series of power amplifi ers from
Crown
®
represents a new era in afford-
able, quality power amplifi cation. All three
models in the series are powerful, rugged and
reliable. They are suited for applications such as
churches, concert tours, stages, disco, pubs, or
any place that requires amplifi er installation.
The three models in the series are the LPS-
800, LPS-1500 and LPS-2500. They are identi-
cal except for output power.
Features include XLR inputs, Speakon
®
and
binding post outputs, stereo/parallel/bridge-
mono mode, power/fault/signal presence/clip
indicators, forced-air cooling; and protection
against shorts, no-load, on/off thumps and
radio-frequency interference. Every LPS Series
amplifi er is backed by a one-year limited war-
ranty.
With over six decades of experience designing
and building rock-solid products, Crown is the
standard in amplifi er technology. So check out
the affordable Crown LPS Series. They are a
powerful argument for quality and value!

Specifi cations
The following applies to units in Stereo mode with 8-ohm loads
unless otherwise specifi ed.
Performance
Sensitivity (for full rated power at 4 ohms):
1.25 V rms.
Frequency Response (at 1 watt): 40 Hz - 20
kHz, +0/–3 dB.
Signal-to-Noise Ratio (below rated power, 20
Hz to 20 kHz, A-weighted): >100 dB.
Total Harmonic Distortion (THD): < 0.5%, 20
Hz - 20 kHz.
Intermodulation Distortion (IMD)
(60 Hz and 7 kHz at 4:1 from full rated output to
–30 dB): < 0.3%.
Damping Factor (8 ohms, 10 Hz - 400 Hz):
>300.
Crosstalk (below rated power):
at 1 kHz: –76 dB.
at 20 kHz: –58 dB.
Input Impedance (nominal): 20 kilohms bal-
anced, 10 kilohms unbalanced.
Output Power: See power charts.
Load Impedance: (Note: safe with all loads).
4 ohms in stereo mode, 8 ohms in bridge-mono
mode.
AC Line Voltage and Frequency Confi gurations
Available (±10%): 120VAC/60Hz,
220VAC/50Hz, 240VAC/50Hz.
Front Panel Controls and Indicators
Fault Indicator: Red LED, one per channel ,
indicates channel shutdown.
Clip Indicator: Red LED, one per channel,
fl ashes when signal is audibly distorting.
Signal Presence Indicator: Green LED, one
per channel, fl ashes when input signal exceeds
–40 dBu.
Power Switch: Push-on, push-off.
Power Indicator: Blue LED illuminates when
amplifi er is on.
Volume Control: Sets output level of each
channel.
Back Panel Controls and Connectors
Reset Button: Resets the circuit breaker.
Output Connectors: One Speakon
®
per channel
connects to loudspeakers. One pair of binding
posts per channel connects to loudspeakers;
accepts banana plugs or bare wire. (European
models do not accept banana plugs.)
Input Connectors: Balanced XLR, one per
channel.
Output Mode Switch: Stereo (dual), Parallel or
Bridge.
