Crown LPS-1500 プリント

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!

The following applies to units in Stereo mode with 8-ohm loads 
unless otherwise specifi ed.

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.

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.

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.

• Stereo/parallel/bridge-mono 

mode

•  Effi cient forced-air cooling prevents exces-

sive thermal buildup

•  Electronically balanced XLR inputs; binding 

post and Speakon

®

 outputs

•  Two level controls, power switch, power 

LED, and six LEDs which indicate signal 
presence, clip and fault for each channel

•  Protection against shorts, no-load, on/off 

thumps and radio-frequency interference
