Martin Wisman MA 2600

Power Amplifier The MA Series professional power amplifiers offer Martin Wisman renowned integrity and can handle exceptionally high power ratings in a compact, light weight 2RU package. The a Series amps also feature Automatic Clip Limiting to protect connected drivers;Impedance sensing to accommodate varying impedance outputs; tunnel cooled,high efficiency heat sinks; and variable speed DC fans to limit the operating temperature and extend amplifier life. Models in the series include the MA 2600 and MA 3200.   Minimum Guaranteed Power 1 kHz with 0.5% THD Stereo, 4 ohms (per ch.) 1280W Stereo, 8 ohms (per ch.) 800W Bridge mono, 8 ohms 2400W Performance Sensitivity (volts RMS) for full rated power at 8 ohms 0.775V, 32dB, 26dB Frequency Response (at 1 watt, 20Hz - 25 kHz) +0dB, -0.5dB Phase Response (at 1 watt , 20Hz to 20 kHz) +10°,-20° Signal to Noise Ratio below rated power A-weighted Total Harmonic Distortion (THD) at 1 full bandwidth power, from 20 Hz to 20 kHz Intermodulation Distortion (IMD) 60 Hz and 7 kHz at 4:1, from full rated output to -35 dBt Damping Factor (8 ohm): 20 Hz to 400 Hz Low Cut:Linkwitz-Riley (24dB/Octave) Off/35Hz/80Hz Low Pass:Linkwitz-Riley (24dB/Octave) Off/80Hz/125Hz Crosstalk (below rated power, 20 Hz to 20 kHz) Common Mode Rejection (CMR)(20 Hz to 1 kHz) DC Output Offset (Shorted input) Input Impedance (nominally balanced, nominally unbalanced) 20 kilohms, 10 kilohms Voltage Gain (at maximum level setting) 40.3dB gain at 0.775volt sensitivity Load Impedance (Note: Safe with all types of loads) Stereo Bridge 4-8 ohms Mono 8 ohms AC Line Voltage and Frequency Configurations Available (±10%) ~220-240 V and 50/60 Hz AC Line Current (both amplifiers draw no more than 90 watts at idle) 12A Construction Ventilation Flow-through ventilation from front to back Cooling Proportional speed fan Dimensions H × W × D: 89mm×483mm×462mm Net Weight 18kg Shipping Weight 21kg
