There’s no reason to limit yourself to 2 channels, even if space is tight. The WA-4×3 is a 4-channel amp you can use any way you like: for a 4-zone system, triphonic, quadraphonic or simply stereo. The impressive number of configurations available makes it an extremely versatile asset. Equally at home in a fixed installation or as a mobile PA system, it offers everything a stereo amp should, but with 4 channels. – Power: – 4 x 200 W RMS at 8 Ω – 4 x 300 W RMS at 4 Ω – 2 x 600 W RMS bridged stereo at 8 Ω – 2 x 200 W RMS stereo at 8 Ω + 1 x 600 W RMS at 8 Ω – Sensitivity at maximum power at 8 Ω: 0.775 mV – Frequency response (1 W) 20 Hz – 25 kHz (+0 dB, -0.5 dB) – Phase response (1 W) 20 Hz – 20 kHz (+10°, -20°) – Signal-to-noise ratio below rated power with A-weighting: > 100 dB – THD over full bandwidth (20 Hz – 20 kHz ) 0.1% – Damping factor at 8 Ω from 20 Hz to 400 Hz > 200 – Input impedance (nominal balanced) 20 kΩ – Input impedance (nominal unbalanced) 10 kΩ – Max output impedance: 4 channels: 4 and 8 Ω – Stereo bridged : 8 Ω – Supply voltage: 220 – 240 V; 50 – 60 Hz – Max current: 8 A (at rest both amps consume no more than 90 W) – Forced ventilation from front to rear – Cooling: proportional ventilation – Dimensions: 483 x 375 x 89 mm – Net weight: 16 kg
