Page 5: Introduction
Introduction Sixteen channel Class D Amplifier The DPA616 is a professional sixteen channel power amplifier, which is capable of delivering a power of 60 Watt to 4 Ohm loads connected to the 16 output channels. When used in bridge mode, it can deliver a power of 120 Watt to 8 Ohm loads connected to the 8 bridged outputs. This way, the DPA616 is the perfect solution for installed Multi-Zone audio distribution systems with 8 or 16 zones. It is designed as a no-nonsense amplifier with only the necessary controls and connections, which creates great simplicity in use and installation. The input connections are all performed with 3-pin Terminal block connectors, allowing the connection of balanced input signals. Every channel is fitted with a separate gain control potentiometer and for every two input connectors is a Stereo / Bridge & Parallel switch provided whereby two channels can be bridged or linked in parallel, avoiding a cable clutter when multiple channels should be fed with the same input signal. The output connections are performed with 4-pin Terminal block connectors allowing connections for separate or bridged output channels. A built-in multipurpose protection circuit protects against DC malfunction, short circuit, overheating and overload. This all is housed in a double rack space, steel 19” rack mount housing. -

This regulation is created to prevent any possible harm to the environment or human health. This product is developed and manufactured with high quality materials and components which can be recycled and/or reused. Please dispose this product to your local collection point or recycling centre for electrical and electronic waste. This will make to sure that it will be recycled on an environmentally friendly manner, and will help to protect the environment in which we all live. CAUTION The symbols shown are internationally recognized symbols that warn about potentional hazards of electrical products. The lightning flash with arrowpoint in an equilateral triangle means that the unit contains dangerous voltages. The exclamation point in an equilateral triangle indicates that it is necessary for the user to refer to the users manual. These symbols warn that there are no user serviceable parts inside the unit. Do not open the unit. Do not attempt to service the unit yourself. Refer all servicing to qualified personnel. Opening the chassis for any reason will void the manufacturer’s warranty. Do not get the unit wet. If liquid is spilled on the unit, shut it off immediately and take it to a dealer for service. Disconnect the unit during storms to prevent damage. -

The selectable modes are ‘Stereo mode’ or ‘Parallel & Bridge mode’. In Stereo mode, each channel is fed with the signal present on the input connector for the corresponding channel. In Parallel & Bridge mode, the input signal for two subsequent channels is linked with each other. The signal present on the inputs of the channels with even numbers (2, 4, 6, 8, ... ) is always linked in pairs for two consecutive channels (Channels 1 & 2, Channels 3 & 4, ... ). Depending how the outputs are connected, the choise between Parallel or Bridge mode will made. (One load for each separate output or one load connected for one pair of channels). How these connections should be made is described in Chapter 3 of this manual. CH 2 CH 1 Bridge Stereo Parallel Gain control with clipping LED: Each channel is fitted with a gain control knob whereby the level for each individual channel can be adjusted. The sensitivity for each channel is individually adjustable within a range of -20 dB and +20 dB. The clipping LED illuminates when the signal reaches the clipping level. CLIP GAIN Output connections: Every two consecutive channels contain an output connector performed using a 4-pin Terminal block connector. Depending of the used operation mode, output connections can be made for each individual channel or two bridged channels together. How these connections should be made is described in Chapter 3 of this manual. Bridge Power inlet: The mains power supply (110~240V AC / 50~60 Hz) has to be applied to this AC power inlet. The connection is made using an IEC power connector and is fitted with a fuse.
