DMA2500 Two-Channel Digital Mixer Amplifier

Features

● Features tactile mechanical control knobs, push buttons, and a heavy-duty rocker-type power switch.
● Two-channel amplifier where each channel can be independently DIP-switch configured for 100V/70V constant-voltage or 8Ω/4Ω constant-impedance outputs at full rated power.
● Six balanced input channels with individual volume control knobs and separate DIP switches for 48V phantom power on each channel.
● One set of RCA AUX2 inputs split into CH1 and CH2, featuring independent volume adjustments.
● One 3.5mm stereo input connector with dedicated, independent volume control for CH1 and CH2.
● Two RCA AMP IN1-2 power amplifier inputs, normalled to PRE OUT1-2 outputs by default.
● Two RCA PRE OUT1-2 preamplifier outputs controlled by CH1/CH2 volume; restricted to 1V output in 100V constant-voltage mode.
● 3.5mm stereo input and MIC1 can be configured as priority inputs, mixed together in any operating mode.
● Two RCA AUX2 OUT1-2 pass-through outputs for audio sources, bypassing CH1/CH2 volume and master level controls.
● Dedicated RJ45 port supporting up to six DMA30W remote touch control panels for adjusting CH1/CH2 volume, zone status, and EFFECT on/off.
● Customizable reverb depth and time with 3 presets and 1 user mode (L/M/S/OFF room sizes); MIC5-6 and OUTSIDE/ROOM zones can independently toggle EFFECT.
● Individual 3-band EQ controls for MIC1-6 inputs: LOW (80Hz ±12dB), MID (2.5kHz ±12dB), and HIGH (10kHz ±12dB).
● DIP-switch enabled standby mode automatically triggers after 10 minutes of audio inactivity (flashing SLEEP indicator) and wakes upon signal detection.
● Connects one DMA30N Remote Bus Network Decoding Terminal via RJ45 (providing audio, data, and power) for network decoding, offline scheduled playback, EMC dry contacts, and network AUX OUT.

Introduction
Specification

This Two-Channel Digital Mixer Amplifier is specifically tuned for mosque sound reinforcement while serving as a versatile solution for gyms, meeting rooms, retail stores, and standard PA systems. When paired with the DMA30N Remote Bus Network Decoding Terminal, it utilizes a single RJ45 audio-and-data bus shared with the DMA30W Remote Control Panel, enabling streamlined installation and centralized remote control.
