Performance
Power Output: See power charts above.
Sensitivity (volts RMS) for full rated power at 4 ohms: 1.4V
Frequency Response (at 1 watt): 22 Hz to 22 kHz: 1 dB.
Phase Response (degrees at 1 watt, 20 Hz to 20 kHz): +5, 18
Signal-to-Noise Ratio:
A-weighted, below rated power: > 102 dB.
22Hz to 22kHz, below rated power: > 97 dB.
Total Harmonic Distortion (THD) at full bandwidth power, from 20 Hz to 20 kHz: 0.5%.
Intermodulation Distortion (IMD):
(60 Hz and 7 kHz at 4:1) from full rated output to 40 dB: < 1%.
Damping Factor (8 ohm) 10 Hz to 400 Hz:
> 200.
Crosstalk (below rated power):
Xs1200 (1 kHz, 20 kHz): >65 dB, >45 dB
Voltage Gain (at maximum level setting):
Xs1200: 47.4:1 (33.5 dB)
Controls
Level: Two or four front-panel, gray rotary level controls, one for each channel.
Power: Front-panel switch; on when in the right-hand position.
Indicators
Signal: Two or four green LEDs, one for each channel, illuminates when the channels input signal level is above 40 dBu.
Clip: Two or four front-panel red LEDs, one for each channel, illuminates when the channels output signal is being overdriven.
Power: Yellow front-panel LED indicates amplifier has been turned on and AC power is available.
AC Mains: Red front-panel LED indicates the presence of AC power at the power cord, even if the amplifier is not turned on.
Fault: Red front-panel LED illuminates when amplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on.
Bridge: Yellow LED indicates that amplifier is in bridge mode (Channels 1 and 2, Channels 3 and 4 in Xs 4300).
Temp: Red LED indicates that channel(s) are in thermal protect mode.
Input/Output
Input Connectors:
XLR-1/4" combo connectors: One per channel, 3-pin female XLR connector and TRS 1/4" phone jack accept balanced or unbalanced signals.
3-pin Phoenix-style connectors (2-channel models only): One per channel, accepts balanced or unbalanced signals.
Input Impedance (nominal) balanced, unbalanced: 20 k ohms, 10 k ohms.
Output Connectors:
Balanced XLR connectors (2-channel models only): One per channel, 3-pin male XLR connector in parallel with XLR-1/4" combo and Phoenix-style input connectors for daisy-chain operation.
5-Way binding post output connectors: One pair per channel; accept banana plugs, spade lugs or bare wire.
Note: Binding post outputs on European models come with safety plugs installed to prevent European power-cord plugs from being inserted. The top & bottom entry positions for these connectors should therefore be used with European models.
4-Pole Speakon output connector (2-channel models only): One connector per channel. Accepts a 4-pole Speakon connector.
