The direct path airflow design reduces the heat buildup significantly and allows for more amplifier channels and output power in slim two rack space chassis. The audio performance of the PA2450L is superior and fulfills the requirements in many demanding long term applications from sound reinforcement, paging or life safety installations. The PA2450L features many of the same comprehensive protection circuits typical in EV amplifiers. Complete protection is provided for high temperature, audio limiters, power up delay and peak current limiters. In addition to the rated output power, the PA2450L provides excellent headroom for a wide dynamic range on music signals. The onboard dynamic limiter ensures that the output clipping of the PA2450L will not will not generate excessive distortion. The amplifier channels can be bridged for more power flexibility. Marked level controls on the rear panel provide hidden reliable level adjustments for each channel. Front panel LEDs indicate signal present, 0 dB, and limit. Phoenix type connectors for inputs and outputs provide an easy rack wiring. 2 Load Impedance 28V/µs <10Hz - 40kHz Damping factor, at 100Hz / 1kHz, 4 Ohm >250 Power Bandwidth THD=1%, Ref. 1kHz, Half Power >10Hz - >50kHz Input Impedance, 20Hz ... 20kHz, Balanced >20kOhm Signal-to-Noise Ratio, A-Weighted Input Sensitivity at Rated Output Power or Voltage, 1kHz 104 dB 0dBu (775mV) THD at rated output power, MBW=80kHz, 1kHz <0.1% IMD-SMPTE, 60Hz, 7kHz <0.1% DIM30, 3.15kHz, 15kHz Crosstalk, Ref. 1kHz, at 10% Rated Output Power <0.1% <-75 dB Power Requirements 120V or 230V, 50Hz 60Hz Protection Audio Limiters High Temperature Peak Current Limiters Turn-On Delay Cooling Front-to-Rear Dimensions (W x H x D), mm 483 x 88 x 406mm (2Ru) 19" x 3.5" x 16" Weight 16.5kg (36.34lbs) Low Impedance Outputs: - Min.
