1 - All measurements taken at the 120VAC line voltage, unless noted. For 240VAC line voltage, current draw will be ~0.5X
the currents listed in the table. Measurements taken while driving amplifier channels with 1kHz sine wave into 8Ω resistive
loads. Loading the amplifiers with 4Ω loads will double the current draw shown in the table.
2 - Nominal reading, ±5W.
3 - We do not recommend running the amplifiers for extended periods of time over the circuit breaker rating. This was done
for testing purposes only.
4 - All channels driven at 330W per channel
5 - Amplifier configured for 240VAC line voltage. Power measurements taken at 240VAC line voltage. Current draw for
120VAC configurations will be ~2X the currents listed in the table.
6 - Thermal Dissipation is in BTU/hr.
7 - For model AT3305, AT3306, AT3307 & AT3308, the table shows the sum total thermal dissipation of both amplifier
banks.
