Appendix D - Power Requirements & Consumption
1
1 - All measurements taken within the 117VAC line voltage range. For 230VAC line voltage range, current draw will be
~0.5X the currents listed in the table. Measurements taken while driving amplifier channels with 1kHz sine wave.
2 - Nominal reading,
±5
W.
3 - We do not recommend running the amplifiers for extended periods of time over the fuse rating. This was done for
testing purposes only.
4 - All channels driven at 300W per channel
5 - 4 channels at 300W per channel.
6 - All channels at 500W per channel.
