Description
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
35 Watts or 1x 70 Watts (Mono). It features Dante® 2-channel digital inputs and outputs, and
2-channel balanced or unbalanced analog inputs and outputs.
Analog input supports microphone input as well as 48V phantom power for condenser
microphones. This product built-in audio DSP for gain, mixing, matrixing, equalizer, volume
and delay control. This amplifier can be controlled via RS-232, TCP/IP and Web GUI. This
product is suitable for a vast range of AV installations.
Features
☆ Advanced 70W Class-D audio amplifier with Dante® integration
☆ 2x 35W@4/8ohm, 1x 70W@4/8ohm
☆ Dante® 2×2 and AES67 audio input/output supported
☆ Balanced/unbalanced analog input and output for cascading connection
☆ Dante® 2CH digital audio, balanced or unbalanced line level analog and AMP outputs
☆ Supports microphone input with 48V phantom power
☆ Audio DSP processing includes gain, ducking, mixing, matrixing, equalizer, volume and
delay control
☆ Audio output supports 8 band PEQ adjustment (with +15dB/-15dB gain), and a maximum
of 50ms delay setting
☆ Auto standby mode (0~100 minutes can be set) with signal sensing
☆ Local 5-12V input trigger for disabling amplifier output
☆ Integrated web page function, which can control the local machine and query the working
status of the product through the web page
☆ Supports network control function, slave devices in the same network segment can be
controlled through the set host
☆ Dante audio support: 44.1kHz, 48kHz, 88.2kHz, and 96kHz sampling rates @ 16/24bit
☆ Dante audio delay supports settings of 2, 3, 4, 5 or 10ms
☆ Flexible control via front panel buttons, RS-232, TCP/IP and Web GUI
☆ Power via PoE or local DC power supply (Amplifier power limited when using PoE)
