Page 4: Introduction
This manual describes the facilities and basic functions of the hardware of the D6 amplifier. A detailed description of the D6 software (firmware) menu structure and access is given in the D6 Software manual, which is also provided with the D6. -

Each unit can be given a unique Device Name to simplify identification and a password protected LOCK function is also incorporated to inhibit unauthorized set up changes. The D6 is housed in a 19" x 351 mm (13.8") 2 rack unit enclosure made from steel. 2.2. -
Page 6: Power Supply
The D6 accepts mains voltages of up to 400 VAC without damage to the unit. -

A or B. The channel is unmuted by briefly pressing the corresponding MUTE switch. - A longer press (approx. 1.5 s) of MUTE A or B places the D6 in Standby mode. Briefly pressing the MUTE A or B switch again powers on the D6 ready for use. -

Display and network remain functional, the display illumination will be switched off after 10 s. Note: When the D6 is set to STANDBY (or the mains power is turned off) the movement of the loudspeaker cones in the cabinets connected is no longer damped by the power amplifier output. -

Either the input signal level is too high or gain reduction exceeds >12 dB. - If in doubt reduce the input gain at the D6 level control. If caused by the gain reduction, the OVL LED stops illuminating. If the condition does not change, the input signal to the D6 is too high (greater than +25 dBu). -
Page 10: Connections
REMOTE SERVICE CH B 4.1. Mains Connector The D6 is a protective class 1 unit. WARNING! A missing earth (ground) contact may lead to dangerous voltages in the housing and controls and may lead to electric shock. - The unit must only be connected to mains voltage supply with protective earth. -
Page 11: Input Digital Aes/Ebu And Link
- Never connect an amplifier output pin to any other in or output connector pin or earth (ground). This might lead to electric shock or damage the unit. The D6 amplifier is supplied with NL4 output connectors [13]. Pins 1+/2+ and 1 /2— are wired in parallel and carry signal. -
Page 12: Remote Interface
4.4. REMOTE interface The D6 is fitted with a 2-wire serial remote control interface, (2 x RJ 45 [14]) carrying CAN-Bus signals. All pins of both connectors are wired in parallel allowing either to be used as the input or output. Where remote control networking conforms to a "Bus or Ring topology"... -

5.1. Rack mounting D6 amplifier enclosures are designed to fit into a standard 19" equipment rack or cabinet. When specifying a rack, be sure to allow extra depth (10 cm / 4" is usually sufficient) to accommodate the cables and connectors at the rear of the amplifier. -
Page 14: Operation
The table gives power figures for various types of signal waveforms. They were measured on a D6 driving a 4 ohm load (both channels) to the clipping point of both channels using a sine wave burst signal of 24 dBu with a variable duty cycle. -

(113° F), the maximum continuous output power is 340 watts total or 170 watts per channel. Again referring to section 5.2.1 - Tab. 3 - "D6 Power balance" - the unit will work properly with e.g. 150 watts total when either - running 4 ohms loads when the signal has a CF of 4.0... -
