Ultra-LD 200W Power Amplifier symmetrical supply voltage of +55 v-55v dc 110 volts be careful. Half of the most beautiful setting eliminates the need for serenity
voltage on the schema must also be given the values ​​of certain regions

Frequency Response at 1W -3dB at 4Hz, -1dB at 50kHz
Input Sensitivity 1.26V RMS for 135W into 8ohm
Input Impedance: ~12kW
Rated Harmonic Distortion < .008% from 20Hz to 20kHz for 8ohm operation; typically .001% Signal to Noise Ratio: 122dB unweighted with respect to 135W into 8ohm (22Hz to 22kHz) Damping Factor 170 with respect to 8ohm at 100Hz; <50 at 10kHz
