XPA-1L
Specifications
Topology:
Fully balanced, fully discrete, quad differential, high current, short signal path,
with user switchable Class A or Class A/B operation.
Number of Channels:
1
Power Output (rated power; THD < 0.1%):
250 watts into 8 Ohms; Class A/B operation.
500 watts into 4 Ohms; Class A/B operation.
35 watts Class A, transitioning to 250 watts Class A/B into 8 ohms; Class A operation.
Note: In Class A mode, the XPA-1L operates in pure Class A mode at all power levels up to
35 watts, at which point it automatically transitions into Class A/B mode.
Rated Power Bandwidth (at rated power; 8 Ohm load):
20 Hz to 20 kHz + / - 0.15 dB.
Minimum Recommended Load Impedance:
4 Ohms (which equals one 4 Ohm load or two paralleled 8 Ohm loads).
Frequency Response:
10 Hz to 80 kHz (+ 0 / - 2 dB).
THD + noise:
< 0.005%
Signal to Noise Ratio (8 Ohm load):
> 90 dB at 1 watt (A-weighted).
> 116 dB at rated power (A-weighted).
Damping Factor (8 Ohm load):
> 500
