Model Description:
Power Amplifier

Model Details

The power amplifi er shall be a solid-state eight-channel model employing
Multi-Mode® (AB+B) output circuitry.
The amplifier shall contain a 3rd generation DSP-based PIP™ (Programmable
Input Processor) module, which shall connect the amplifi er to a
100 Mbps Ethernet network, allowing it to be remotely controlled and
monitored via System Architect™ software. In addition, the input module
shall allow the transport of real-time digital audio via CobraNet™ over the
same Ethernet network.
The input module’s processors shall provide digital signal processing.
Audio routing, faders, meters, polarity & mute, input compressors, fi lters,
delays, multimode output limiters, error reporting, and load monitoring
shall be available. A built in noise generator and sine-wave generator provide
noise shall provide masking and test capabilities. The enhanced AUX
port capability shall allow the user to interface with the amplifi er to provide
external manual control and monitoring.



Features:

  • High power density. All two channel models and four channel model in a 2RU chassis, eight channel model in a 3RU chassis
  • Crown Switching Power Supply for lighter weight
  • Selectable "Constant-Voltage" or low-impedance (4/8 ohm) operation per channel on 2-channel models, and per channel-pair on 4-and 8-channel models
  • 100V direct outputs on CTs 2000, CTs 3000, CTs 4200, and CTs 8200
  • Legendary Crown class-I (BCA) and AB+B output topologies offer the best in amplifier reliability
  • 4- and 8-channel models offer perfect independent power solutions for multi-zoned systems· "FIT" (Fault Isolation Topology) circuitry on 4- and 8-channel models isolates fault conditions without affecting neighboring channels
  • Comprehensive array of indicators provide accurate diagnostics
  • Two-channel models are fully PIP2-compatible. Multi-channel models accept MC accessory modules.


  • Specifications:

    The amplifi er shall contain protection from shorted, open and mismatched

    loads, general overheating, DC, high-frequency overloads, under/over voltage,

    and internal faults.

    The amplifi er shall contain FIT (Fault Isolation Topology), which isolates

    channel-specifi c faults and prevents them from affecting remaining channels.

    If an amplifi er channel starts to overheat, the Thermal Level Control

    (TLC) circuit shall engage that channel’s input compressor in an amount

    proportional to the amount of overheating, in order to generate less heat.

    If the channel becomes too hot for safe operation, the channel shall shut

    off, and the Thermal Indicator for that channel shall fl ash brightly to alert

    the user that a state of thermal stress or overload has caused the channel

    to shut down.

    The front-panel control shall be a power switch.

    Rear-mounted controls shall include Channel Level Controls and a Mode

    Switch. The Mode Switch (used on each consecutive pair of channels)

    is a four-position switch which selects among Dual 8/4 ohms, Dual 70V,

    Bridge-Mono 16/8 ohms, and Bridge-Mono 100V.

    The recommended load impedance in Dual mode shall be 4/8 and 25 ohms

    (70V). The load impedance in Bridge-Mono mode shall be 8/16 ohms and

    50 ohms (100V). The amplifi er shall be safe when driving any kind of load,

    including highly reactive ones.

    Rear-mounted output connectors shall be one four-pole terminal strip for

    every two channels with a touch-proof cover. Rear-mounted input connectors

    shall be removable Phoenix-style barrier connectors for balanced

    input.

    Front panel indicators shall include a yellow Bridge-Mode Indicator (one

    per channel pair) that illuminates when the channel pair’s Mode Switch is

    set to the “Bridge” position (and fl ashes if the Mode Switch is changed

    while the amplifi er is powered up, indicating that the amplifi er must be

    powered off and on to reset the Mode), a green Ready Indicator (one

    per channel) that illuminates when the channel is initialized and ready

    to produce audio output, a green Signal Indicator (one per channel) that

    illuminates to indicate the presence of input signals above -40 dBu, a red

    Clip Indicator that illuminates when the THD of the channel’s output signal

    rises to a level typically considered as the onset of audible clipping (and

    illuminates during Thermal Level Control or input overload), a red Thermal

    Indicator (one per channel) that fl ashes when a state of thermal stress or

    overload has caused the channel to shut down (and fl ashes in all channels

    if the power supply goes into thermal overload), a red Fault Indicator

    (one per channel) that fl ashes when a fault condition has occurred in the

    channel, a yellow Data Indicator that indicates IQ Loop data activity (if the

    amplifi er is equipped with an IQ-MC module and is connected to an IQ

    Loop), and a blue Power Indicator that illuminates when the amplifi er has

    been turned on and AC power is available (and illuminates when the ampli-

    fi er shuts off due to an under-/over-voltage condition on the AC mains).

    The power amplifi er shall meet or exceed the following performance criteria.

    Input sensitivity for rated output: 1.4 V. Rated output with eight channels

    driven in Dual mode with 0.1% THD (20 Hz to 20 kHz): 175 watts per

    channel into 4 ohms; 155 watts per channel into 8 ohms, and 185 watts

    per channel (70V). Rated output in Bridge-Mono mode with four channel

    pairs driven at 0.1% THD (20 Hz to 20 kHz): 350 watts per channel pair

    into 8 ohms; 310 watts per channel pair into 16 ohms, and 185 watts per

    channel pair (100V). Signal to Noise Ratio below rated power (20 Hz to 20

    kHz): 100 dB unweighted. Phase Response: ±35 degrees from 10 Hz to 20

    kHz at 1 watt. Frequency Response: 20 Hz to 20 kHz, ±0.5 dB at 1 watt into

    8 ohms per channel in Dual mode. Damping Factor: greater than 180 from

    10 to 400 Hz. Crosstalk (below rated power, 20 Hz to 1 kHz): greater than

    80 dB. Intermodulation Distortion (60 Hz and 7 kHz at 4:1, from 163 milliwatts

    to full bandwidth power): less than 0.05% typical. Total Harmonic

    Distortion at 1 watt from 20 Hz to 20 kHz: less than 0.05%. Common Mode

    Rejection (20 Hz to 1 kHz): greater than 50 dB. DC Output Offset (shorted

    input): less than 5 mV. Maximum Input Level (before input compression):

    + 22 dBu rms. Power Draw at Idle (120 VAC mains, all channels in 4/8 ohm

    mode): 58 watts. Power Draw at Idle (120 VAC mains, all channels in 70V

    mode): 77 watts.

    The amplifi er chassis shall be constructed of steel with a durable black

    fi nish and shall be designed for continuously variable-speed forced-air

    ventilation from the front panel to the back panel.

    The dimensions of the amplifi er shall allow for 19 inch (48.3 cm) EIA

    standard (RS-310-B) rack mounting. The amplifi er shall be 5.25 inches

    (13.3 cm) tall, and 16.25 inches (41.3 cm) deep behind the rack-mounting

    surface.

    The amplifi er shall weigh 36 pounds, 6 ounces (16.5 kg).
