DPA4410/11

400 watt 4 Channel Power Amplifier

Key Features:

• Configurable as a 2x200, 2x100 & 1x200, or 4x100 amplifier.

• Operation with 70V loudspeaker networks or 4/8 ohms low-impedance systems

• Outputs protected against idling, short-circuits, over-temp and load variations.

• Integrated Remote Module for control and monitoring (DPA4411 only)

• Routing switch for parallel operation of the amplifier’s inputs

• Integrated Standby Power Supply

• Remote-Start function for mains and battery

operation with inrush current limiter protection.

• Power-on noise attenuation.

• Status-LED indicators.

• LED meters with CLIP indication.

• Active, temperature-controlled ventilation.

General Description:

The DPA4410/11 amplifiers have been specially designed to ensure durable performance and reliable operation of sound reinforcement systems with several independent loudspeaker lines. The units are best suited for paging and pre-recorded message installations, alert systems, and for general music applications in industrial enterprises, offices, multifunction halls, sport arenas, schools, churches, hotels, hospitals, super markets, cruise ships, and similar venues.

The DPA4410/11 amplifiers can either be operated on the AC mains or connected to an external 24 V battery power source. Switching to battery operation is accomplished via an internal relay.

The DPA4411 provides the following remote monitoring functions when used within a ProAnnounce system:

• Setting input levels on channels 1-4

• Reading level values of the audio level controls.

• Setting level offsets via virtual controllers.

• Mute function (via level controls).

• Remote control power operation ON/OFF.

• Battery operation remote control ON/OFF.

• Monitoring and fault message transmission of

thermal overload warnings on the mains transformer or power output stages.

• Monitoring of the functioning of the power output

stages 1 to 4 via pilot tone signal.

• Ground fault detection for loudspeaker lines.

Architecture & Engineering Specifications:

The remote control amplifier unit shall provide the following remote monitoring functions:

• Setting input levels on channels 1-4

• Reading level values of the audio level

controls.

• Setting level offsets via virtual controllers.

• Mute function (via level controls).

• Remote control power operation ON/OFF.

• Battery operation remote control ON/OFF.

• Monitoring and fault message transmission of

thermal overload warnings on the mains transformer or power output stages.

• Monitoring of the functioning of the power output stages 1 to 4 via pilot tone signal.

• Ground fault detection for loudspeaker lines.

The amplifier shall either be powered by AC mains or connected to an external 24 V battery power source. Switching to battery operation shall be accomplished via an internal relay.

The amplifier shall be 3 RU in height and be configurable for 2x200, 1x200 & 2x100, or 4x100 watt operation. Jumpers located on the unit chassis shall

accomplish these operation mode changes. The output channels must be driven through on-board transformers.

The amplifier shall be the Dynacord ProAnnounce DPA4411 or DPA4410.
