DDA-150DT

Beschrijving

Introduction

This product is designed as a two-channel amplifier using class D amplifier technology. It can

be used for powering low impedance (4Ω/8Ω) stereo systems with a maximum power of 2x

75 Watt, while bridging to a constant voltage (100V and 70V) is possible with a maximum

output power of 150 Watt. It features Dante® 2CH digital inputs and outputs, and balanced or

unbalanced line level analog inputs and outputs.

This amplifier can be controlled via RS-232, LAN, MMA-CON1 controller and Web GUI. It also features built-in DSP,

auto-standby and maximum durability. It is suitable for a vast range of AV installations.

Features

☆ Dante® 2CH digital audio IN, routable in the software

☆ Dante® 2CH digital audio OUT, routable in the software

☆ Built-in audio DSP processor

☆ Switching between Lo-Z and Hi-Z can be achieved to adapt to various types of speaker

installations.

In Lo-Z output mode, bridge mode 150 Watt or two-channel 2x 75 Watt 4Ω/8Ω can be

selected.

In Hi-Z output mode, constant voltage 70V/100V can be selected.

☆ Independent input gain, output EQ and volume control

☆ 48KHz sampling rate, 24bit independent A/D and D/A converters

☆ 5-12V trigger input

☆ Auto standby

☆ Flexible control via RS-232, LAN and Web GUI

☆ Half rack design/one rack design, brackets included.
