3 pairs: 150 W each
Load Impedance
Drives any load; 4 ohms to 8 ohms recommended.
Bridged: 8 ohms recommended.
Frequency Response
20 Hz to 20 kHz, +0/-1 dB
THD + Noise
>0.05%, 1 kHz, at rated output
>0.15%, 20 Hz to 20 kHz, at rated output
Signal To Noise Ratio
20 Hz to 20 kHz, unweighted:
>100 dB
Voltage Gain
Each channel: off to 29 dB
Input Sensitivity
0.8 V for rated output
AC Power
120 V or 240 V, 50/60 Hz.
Idle power: 36 W
Typical use max. power: 780 W
Dimensions
3.5 in. x 19 in. x 12.7 in.
(8.9 cm x 48.3 cm x 32.3 cm)
Weight
25 lbs (11.4 kg) shipping weight
Indicators
Power: Blue light on the front panel indicates that the unit is powered.
Signal Presence: Green lights on the front panel for each channel indicate presence of output signal.
Peak: Red lights on the front panel for each channel indicate the onset of clipping (moderate intensity) and audible distortion (bright intensity).
Temperature: Yellow light on the front panel indicates maximum operation of the cooling system.
Cooling System
Forced air on demand, intake from front vents. Long-life (rated over 20 years operation at full speed), low-noise fan. Temperature sensing at each heatsink.
Normal: Fan idles at low speed.
Warm Heatsink: Fan is triggered to high speed during high-level audio output at any channel.
Hot Heatsink: Fan operates at full speed, and yellow temperature indicator lights, until heatsinks return to warm threshold.
Input/Output
Input Connectors: Balanced screw terminal connections.
Also available: the MPR-450R has gold RCA input connectors.
Input Impedance: 15K ohms differential
Output Connectors: Heavy-duty binding posts/double banana jacks; accommodate up to 10-gauge cable.
Output Impedance: 30 milliohms
Controls
Power: Rocker switch on the front panel for turning the unit on/off.
Gain Controls: Controls on the rear panel allow the gain of each channel to be set independently.
Bridging: Three switches on the rear panel allow each pair of channels to be bridged for a single channel with greater output power.

刚拿来时看样子有点没有信心那知道一开声有点不相信自己的耳朵。出来的声音开朗又细致,解析力又高难得的声场很稳定位很准。反正声音很动听,对欧美机器真要刮目相看啊。 |
