Massive transformers
DR series are built around a massive heavy-duty toroidal transformer. This transformer delivers the ability for rapid burst power, which leads to improved dynamics.
Protection
An DR series amplifier features comprehensive protection circuitry. This ensures that no matter what problems might exist with external cabling, AC power or loudspeakers, the amplifier will protect itself, and its surroundings.
Front panel LED’s give immediate and clear feedback to the situation. Should an external fault occur, the red LED ‘Fault’ light will illuminate and the amp will go into Protection mode. A rear panel ‘Breaker’ button is then available to reset the amplifier once the external fault has been diagnosed and removed.
Handy ‘Clip’ LED’s are also visible from the front panel. Even from a distance, its simple and clear to see and understand the status of the amp.
A look behind the scenes
Around the back of the DR are the balanced inputs and outputs along with configuration switches.
A handy feature are the 2 x XLR link outputs which allow for easy ‘daisy chaining’ of multiple amps – removing the need for external patching or excessive cabling. Around the back is also the input sensitivity switch selectable between 0.775 V, 1 V and 35 dB.
The main ‘Bridge / Stereo / Parallel’ mode switch is also on the rear. STEREO mode makes the two channels work independently. CH1 input signal goes to CH1 output and CH2 signal goes to CH2 output.
In BRIDGE mode the CH1 output is used with the described pin out +1 = + / +2 = –
This is controlled by using the CH1 volume control.
PARALLEL mode makes CH1 input signal go to both CH1 and CH2 output sockets. The input socket of CH2 has no effect. The channel volumes can be adjusted independently.
