The DVA 700 has four independent internal Class AB solid state channels, fed from two XLR balanced inputs only. This provides two balanced audio output channels, each of the two output channels consisting of an active plus and an active minus channel.
There are no single ended to balanced adapter circuits at the inputs, just XLR jacks wired directly to the audio channels to provide the purest possible full differential balanced audio possible.
Each of the four independent internal channels have regulated small signal power supplies and regulated output circuits.
Each of the four independent audio channels use four double die Exicon power mos-fet power transistors for near unlimited current capacity. Sixteen double die devices in total, equivalent to 32 normal 200V 250W 8 amp devices. This keeps the output impedance vanishing low and load interaction nearly nil. The DVA 700 will grab your speakers and make them sing like never before.
Each audio circuit is so stable no DC balance adjustments are needed or provided.
If you own pure differential equipment ahead of the DVA 700 you will be astonished how much better your system will sound when all of the input and output conversion circuits are eliminated.
The DVA 700 uses a custom toroidal power transformer feeding 16 active regulated power supplies to provide incredible dynamic range, bass extension, transient detail, and air. All of the power supply parts are selected for long life and operate well within their specification ratings.
A unique engineering feature of the DVA 700 power amplifier is that it uses independent, actively regulated power supplies for each channel's output transistors. This provides superior separation, bass control, and micro-dynamics.
The DVA 700 operates with standard 120 Volt power, has an IEC power jack, and includes a 120 V power cord. For international use, a 240 Volt (50-60 Hz) option is available at additional cost.
The DVA 700 is Class AB and operates as Class A at normal listening levels.
The combination of our design ideas allows the amplifier to run cooler, last longer, and be amazingly fault tolerant.
The DVA 700 produces 350 watts per channel 20 to 20 kHz into 8 ohms at less than 0.01% THD. The DVA 700 has a total of 16 double-die mos-fet output transistors equivalent to 32 normal 200V 250W 8 amp devices.. The DVA 700 handles speaker loads of 4 Ohms and up.
Plenty of power for any rational loudspeaker.
