Amplifier Output Connections
The DVA4x500 amplifier is fitted with a twin high-current, color-coded binding posts (for Banana
connector, spade lugs or bare wire) per output amplifier channel. The appropriate conductor terminations are shown
on the rear panel of the unit.

Load Matching
Each output of the device can be optimised to drive either a low impedance load (e.g. 4 or 8 Ohms),
or a Constant Voltage (C.V.).
The bridge pair channel of a DVA4x500 can deliver 1000W in to 8Ohms, therefore the RMS voltage
at the speaker terminals when delivering this will be √(1.000 x8) = 89.44V.
If each channel is not loaded to full capacity of 1.000W (typically a 70V / 100V application will not
load it this heavily) then the voltage will be higher than this because the power rails will not be sagging so much;
approximately 100V.
Dependent on which voltage you use with a bridged pair of channels, the DVA4x500 will be able to
overdrive a 70V line by either 3dB or 4.7dB and a 100V line being driven perfectly or overdriven by 1.6dB.
IMPORTANT:
Binding post outputs come with safety plugs installed to prevent European
power plugs from being inserted.
