The BasX A-500 is a five channel power amplifier. The BasX A-500 combines classical audiophile amplifier architecture, based on a heavy-duty linear power supply, and a carefully designed high current short signal path Class A/B output stage, with advanced microprocessor-controlled monitoring and protection circuitry, to deliver superb sound quality at a truly reasonable price.
Power Output (two channels driven):
110 watts RMS per channel; 20 Hz – 20 kHz; THD < 0.1%; into 8 Ohms.
190 watts RMS per channel; 1 kHz; THD < 1%; into 4 Ohms.
Power Output (all channels driven):
80 watts RMS per channel; 20 Hz – 20 kHz; THD < 0.1%; into 8 Ohms.
Power Bandwidth (at rated power; 8 Ohm load): 20 Hz to 20 kHz (+ / – 0.07 dB)
Broad Band Frequency Response: 5 Hz to 80 kHz +0/-1.8 dB
THD + noise: < 0.02% (A-weighted); ref rated power
Signal to Noise Ratio (8 Ohm load):
> 120 dB; ref rated power; (A-weighted).
> 100 dB; ref 1 watt; (A-weighted).
Minimum Recommended Load Impedance (per channel): 4 Ohms
(which equals one 4 Ohm load or two paralleled 8 Ohm loads).
Damping Factor (8 Ohm load): > 500.
Input Sensitivity (for rated power; 8 Ohm load): 1.2 V.
Gain: 29 dB.
Input Impedance: 27 kOhms.
Input Connections: Unbalanced (RCA); one each per channel.
Speaker Output Connections: Audiophile grade 5-way binding posts.
Trigger Input: 5 – 12 V (AC or DC); <10 mA input current required.
Trigger Output: 12 VDC; can drive any load up to 120 mA.
115 VAC or 230 VAC @ 50 / 60 Hz (automatically detected).
Standby: push button (halo ring changes color to indicate Standby or On).
Status LEDs: one per channel; blue.
Status LEDs change to red to indicate a fault condition.
AC Power switch: rocker switch (switches AC main power).
Status LEDs switch: disables front panel Status LEDs.
The BasX A-500 is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions.
