Crownʼs new CTs series of power amplifiers are remarkable for their loud, punchy sound; sustained, tight bass; and superior protection against overheating and overload. This paper explains the design features behind those advantages. After reading this information, youʼll know why Crown CTs amps sound better than the competition. CTs amplifiers can provide large amounts of power into various loads, such as 2, 4, 8 ohms and 70V. With most power amps, the maximum output power tends to drop as the load impedance increases. But with the CTs series, the power stays the same at almost any impedance. 2-ohm Dual (per Ch.) 250W 4-ohm Dual (per Ch.) 600W 8-ohm Dual (per Ch.) 600W 16-ohm Dual (per Ch.) 300W 70V Dual (per Ch.) 600W 4-ohm Bridge 500W 8-ohm Bridge 1200W 16-ohm Bridge 1200W 140V Bridge 1200W Crown switching power supply for less weight Sustained Power on long-duration signals due to regulated, "stiff” power supplies with incredible energy storage (huge filter capacitors). Extra Hidden Power during high-level transients and during incomplete use of all the channels. Overheating and overload protection thanks to the sophisticated TLC circuitry which compresses the signal only when needed. Compression is controlled not by temperature, but by signal voltage. This keeps the loudness up during compression more than with competitive amps.

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.
