ELECTRO VOICE CP 1800 2X600W POWER AMPLIFIER

CP1800
Compact Precision Series Class H Power Amplifier

2 x 1,100W into 2 ohms Highly efficient Class-H design 2 rack space units Only 35 lbs (16 kg)
Complete protection package Dynamic limiter General Description: Electro-Voice?s new Precision
Series Compact amplifiers offer proven Precision Series performance and reliability in a new compact,
lightweight format. This is made possible by incorporating a highly efficient Class-H design, which
results in considerably less heat being generated. This allows the overall size of the amplifier to be
reduced substantially without sacrificing performance or reliability. The CP1800 supplies up to 2 x
900 watts into 2 ohms and 2 x 600 watts into 4 ohms. Dedicated for smaller full-range speaker systems
and hi-frequency components in multiway systems. The CP1800 uses a conventional transformer power
supply.

Crown DSi 2000 2x800W-4Ω Power Amplifier

The Crown? DSi 2000 power amplifier shall be a solid-state two-channel model with a switch-mode universal power supply. A rear-panel HD-15 connector shall provide input/output connectivity between the DSi amplifier and the DSi-8M System Monitor.

The outputs shall be usable as stereo or bridged-mono modes of operation.

The bridged-mono mode shall bridge the outputs to provide increased output voltage.

Front panel controls and indicators shall include the following:

Level: Detented rotary level control, one per channel.

Power Switch: On/off switch applies AC power to the amplifi er.

Sel/Prev/Next Buttons: Three buttons near the LCD screen shall be used to access menu items and front panel lockout.

LCD Screen: Backlit liquid crystal display shows speaker presets and signal processing.

Signal Indicator: Green LED, one per channel, illuminates when a very low-level signal is present at input.

?10 Indicator: Green LED fl ashes when output signal exceeds ?10 dB below clip.

?20 Indicator: Green LED fl ashes when output signal level exceeds ?20 dB below clip.

Ready Indicator: Green LED, one per channel, illuminates when the amplifier is ready to produce audio.

Clip Indicator: Red LED, one per channel, turns on at the threshold of audible distortion.

Temp Indicator: Red LED, one per channel, illuminates under excessive temperature conditions.

Power Indicator: Blue LED illuminates when the amplifi er has been turned on and has power.

Rear panel controls and connectors shall include the following:

AC Line Connector: NEMA 5-15P (15A).

Input Connector: Two 3-pin removable Phoenix-type connectors each accept a balanced line-level input signal.

Output Connectors: 4-position barrier strip with connectors for dual louspeakers or bridge-mono loudspeaker.

HiQnet USB Connector: Type B, connects to a HiQnet network.

HD-15 Connector: For cinema I/O compatibility with DSi-8M System Monitor.

The amplifier shall have the following specifications:

Output Power: 2 ohm Stereo (per channel): 1,000W with 1% THD, 4 ohm
