CROWN MA-3600VZ (เพาเวอร์แอมป์ 1120w X 2 ที่ 8 โอมห์)

Power Stereo (per channel) : 1,800w @ 2ohm, 1,560w @ 4ohm, 1,120w @ 8ohm, Bridge-Mono 3,505w @ 4ohm, 3,140w @ 8ohm.

FEATURES

  • Crown’s Grounded Bridge™ design delivers large voltage swings without using easily stressed output-transistor confi gurations like conventional amplifiers; the results are lower distortion and superior reliability
  • Patented ODEP® (Output Device Emulation Protection) circuitry compensates for overheating and overload to keep the amplifier working when others would fail
  • IOC® (Input/Output Comparator) circuitry immediately alerts of any distortion exceeding 0.05%, providing dynamic proof of distortionfree performance
  • MA-5002VZ accepts Crown PIP2 modules. MA-3600VZ accepts only the PIP-Lite module when fitted with the IQ-PIP-USP2 Adapter
  • Patented Variable Impedance (VZ®)power supplies for each channel provide excellent crosstalk characteristics and the best power matching to your load; in the MA-5002VZ, three special modes are provided to control how and when the supplies shift impedance modes
  • Very low harmonic and intermodulation distortion result in the best dynamic transfer function in the industry
  • MA-5002VZ only: Independent error-driven compressor for each channel that can be set for fast or slow attack and release times
  • Full protection from shorted, open and mismatched loads; general overheating; DC; high-frequency overloads; and internal fault conditions

SPECIFICATIONS

Power

Output Power: The following are guaranteed minimums for standard 1-kHz power from 120 VAC, 60 Hz North American units. Maximum average watts per channel (unless in Mono mode) at 1 kHz with 0.1% or less THD.

Stereo mode with both channels driven:
1800 watts into 2 ohms.
1565 watts into 4 ohms.
1120 watts into 8 ohms.

Bridge-Mono mode:
3505 watts into 4 ohms.
3140 watts into 8 ohms.

Parallel-Mono mode:
3555 watts into 1 ohm.
3190 watts into 2 ohms.

Load Impedance: Rated for 16, 8, 4, and 2 ohm use only. Safe with all types of loads, even reactive ones.

AC Power Requirements: 100 VAC, 50/60 Hz; 120 VAC, 50/60 Hz; and 230 VAC, 50/60 Hz units are available. 230 VAC, 50/60 Hz units can be used with 220 and 240 VAC. All versions draw 90 watts or less at idle. 100 and 120 VAC units can draw up to 30 amps of current; 230 VAC units can draw up to 15 amps.

Performance

  • Frequency Response: 0.1 dB from 20 Hz to 20 kHz at 1 watt.
  • Phase Response: 10 from 10 Hz to 20 kHz at 1 watt.
  • Signal-to-Noise Ratio: Greater than 105 dB below rated output (20 Hz to 20 kHz, A-weighted); 100 dB below rated output (20 Hz to 20 kHz, no weighting).
  • Harmonic Distortion (THD): At rated output, less than 0.05% from 20 Hz to 1 kHz increasing linearly to less than 0.1% at 20 kHz.
  • IM Distortion (IMD): Less than 0.05% from 368 milliwatts to full rated output.
  • Damping Factor: Greater than 1,000 from 10 Hz to 400 Hz.
  • Slew Rate: Greater than 30 volts per microsecond.
  • Voltage Gain: (At maximum output) 20:1  6% or 26 dB  0.25 dB at +26 dB gain setting, and 124.6:1  6% or 41.9 dB  1.0 dB at 0.775 volt sensitivity.

Controls

  • Enable: A front panel push button used to turn the amplifier on and off.
  • Level: A 31-position detented rotary attenuator for each channel located on the front panel used to control the output level.
  • Stereo/Mono: A three-position back panel switch used to select Stereo, Bridge-Mono or Parallel-Mono operation.
  • Sensitivity: A three-position switch located inside the PIP compartment used to select one of three input sensitivities for both channels: 0.775 volts or 1.4 volts for standard 1 kHz power or a voltage gain of 26 dB.
  • Input Ground Lift: A two position back panel switch used to isolate the phone jack signal grounds from the chassis (AC) ground.
  • Reset: A back panel button for each channel used to reset the corresponding power supply. 100 and 120 VAC units have 15 amp circuit breakers. 230 VAC units have 7.5 amp circuit breakers.

Indicators

Enable: This amber indicator is on when the amplifier is switched on to show that the low voltage power supply is operating.

Signal / IOC: Two green indicators flash with medium intensity in sync with the amplifier’s outputs to show signal presence. In the unlikely event the output waveform differs from that of the input by 0.05% or more, they flash brightly to indicate distortion. As sensitive distortion indicators they provide proof of performance. Note: It is normal for the Channel 2 IOC indicator to remain on in Parallel-Mono mode.

ODEP: Each channel has a multifunction LED (light emitting diode) indicator that shows the channels energy reserve status. Normally, the LEDs are brightly lit to show that reserve energy is available. In the rare event that a channel has little reserve, its indicator dims in proportion to ODEP limiting. An ODEP indicator may also turn off under other, more unusual circumstances.

Input/Output

  • Input Connector: Balanced -inch phone jacks on chassis and internal PIP connector. (Balanced 3-pin XLR connectors are provided on the P.I.P.-FX which is a standard feature.)
  • Input Impedance: Nominally 20 k ohms, balanced. Nominally 10 K ohms, unbalanced.
  • Input Sensitivity: Switchable between 0.775 V (unbalanced) for rated output or a fixed voltage gain of 26 dB.
  • Output Connector: Color-coded dual binding posts (banana jacks).
  • Output Impedance: Less than 10 milliohms in series with less than 2 microhenries
  • DC Output Offset: (Shorted input) 10 millivolts.

Output Signal

Stereo: Unbalanced, two-channel.
Bridge-Mono: Balanced, single-channel. Channel 1 controls are active; Channel 2 controls are inactive and not removed from operation.
Parallel-Mono: Unbalanced, single-channel. Channel 1 controls are active; Channel 2 controls are inactive but not removed from operation.

Protection

Macro-Tech amplifiers are protected against shorted, open or mismatched loads; overloaded power supplies; excessive temperature, chain destruction phenomena, input overload damage and high-frequency blow-ups. They also protect loudspeakers from input/output DC and turn-on/turn-off transients.
If unreasonable operating conditions occur, the patented ODEP circuitry proportionally limits the drive level to protect the output devices, particularly in the case of elevated temperature. Transformer overheating results in a temporary shutdown of the offending channel. When it has cooled to a safe temperature, the transformer automatically resets itself. Controlled slew rate voltage amplifiers protect against RF burnouts, and input overload protection is provided by current-limiting resistance at the input.
Turn On: The four second turn-on delay prevents dangerous turn-on transients. Turn-on occurs at zero crossing of the AC waveform, so power sequencers are rarely needed with multiple units. Note: The turn-on delay time may be changed. Contact Crowns Technical Support Group for details.
Circuit Breaker: Circuit breaker current ratings vary based on the AC operating power.

Construction

Durable black powder coated steel chassis and aluminum front panel with Lexan overlay; specially designed flow-through ventilation from front to side panels.

Cooling: Forced-air with custom heat diffusers and patented circuitry to promote uniform dissipation.

Dimensions: 19 inch (48.3 cm) standard rack mount (EIA Std. RS-310-B), 3.5 inch (8.9 cm) height, 16 inch (40.6 cm) depth behind mounting surface and 2.5 inches (6.4 cm) in front of mounting surface.

Weight: Center of gravity is 6 inches (15.2 cm) behind the front mounting surface.
