Power Amplifier
XH200
2 120 V model
The distribution power amplifier shall provide two channels of amplification. This amplifier shall draw 400 W or less at 1/8 rated power at 70 V output. The
power amplifier shall be capable of operation from a 120 V, 60 Hz line. The amplifier shall meet the following performance criteria. 70-volt sine-wave output
power of 200 watts, 40 Hz to 20 kHz at < 0.1% THD+N, with both channels driven; and 100-volt sine-wave output power of 200 watts, 40 Hz to 20 kHz at <
0.1% THD+N, with both channels driven. Total harmonic distortion (THD+N) shall be less than 0.1% at 40 Hz - 20 kHz, half power. Intermodulation
distortion (IMD) shall be less than 0.1% using the SMPTE standard of 60 Hz and 7 kHz in a 4:1 ratio respectively with an 8 ohm load. Frequency response
shall be from 80 Hz to 20 kHz (+0 dB, -0.5 dB). Residual noise at 20 Hz - 20 kHz shall be less than -65 dBu. Input shall be electronically balanced, with a
minimum impedance of 20 kohm balanced and 15 kohm unbalanced. The voltage gain shall be 38 dB (100 V), 35 dB (70 V). Maximum input voltage shall
be +22 dBu. Built-in protection circuitry shall monitor voltage and current levels to minimize potential damage from overloads, and disable output during
shorts, DC offset, or excessive operating temperatures 90°C. The relay shall also delay amplifier connection to the load during turn-on for six seconds while
the protection circuitry analyzes the load. In-rush current limiting shall minimize turn-on current surges when multiple units are powered-up remotely to
prevent AC breaker overload. The amplifier shall employ forced-air cooling with dual temperature-controlled fans, variable in speed for minimum acoustic
noise. Air flow shall be from front to rear. The front panel shall have a recessed AC power switch, LED indicator. The LED indicators shall indicate
POWER, SIGNAL, PROTECT/MUTE and CLIP/LIMIT condition. The front-panel shall have two 31-step volume knobs (one per ch). Rear-panel mode
switches shall provide two modes (70 V/100 V).The rear-panel shall have 12 dB/oct HPF switch (fc=40 Hz or 80 Hz). Rear panel input connectors shall be a
3-pin detachable terminal block for each channel. Rear panel output connectors shall be a Barrier strip. Dsub15P Data Port connectors shall allow remote
control and monitoring. Isolation components shall be provided and output devices shall be mounted by individual screws to minimize sonic degradation
caused by vibration. The amplifier shall conform to the latest EU RoHS hazardous substances and WEEE directives. It shall use only two standard rack-
spaces and its dimensions shall be 480 mm W x 412.2 mm D x 88 mm H (18-7/8” x 16-1/4” x 3-7/16”). Weight shall be 9.8 kg (21.6 lbs). The amplifier shall
be YAMAHA XH200.
2 230 V model
The distribution power amplifier shall provide two channels of amplification. This amplifier shall draw 400 W or less at 1/8 rated power at 70 V output. The
power amplifier shall be capable of operation from a 230 V, 50 Hz line. The amplifier shall meet the following performance criteria. 70-volt sine-wave output
power of 200 watts, 40 Hz to 20 kHz at < 0.1% THD+N, with both channels driven; and 100-volt sine-wave output power of 200 watts, 40 Hz to 20 kHz at <
0.1% THD+N, with both channels driven. Total harmonic distortion (THD+N) shall be less than 0.1% at 40 Hz - 20 kHz, half power. Intermodulation
distortion (IMD) shall be less than 0.1% using the SMPTE standard of 60 Hz and 7 kHz in a 4:1 ratio respectively with an 8 ohm load. Frequency response
shall be from 80 Hz to 20 kHz (+0 dB, -0.5 dB). Residual noise at 40 Hz - 20 kHz shall be less than -65 dBu. Input shall be electronically balanced, with a
