The new Inter-M DPA-50E is a Eight channel (8 x 50W) 100v Line Class D Power Amplifier for professional PA, VA and background music.The DPA series is a high quality commercial amplifier that can reproduce crisp, detailed sound without noise with high S/N of over 100dB and low THD of less than 0.1%. Therefore, it is very suitable for BGM playback.
The Inter-M DPA-50E is a Eight channel (8 x 50W) 100v line / Low Impedance Class D Amplifier for professional zoned public address, AV and background music installed audio systems and rack builds.
Housed within a compact and discreet 2U high casing, this 8 x 50 watt 100v line / Low Z power amplifier offers both size and weight reduction benefits.
The DPA-50E's Class-D amplification circuitry also ensures significant efficiency improvements (typically 90% efficient compared to an average of 40% efficiency expected from conventional amplification.
Each channel also provides Dual Input capabilities, allowing a priority input signal to override the standard/normal input signal an ideal feature to support emergency paging systems.
HIGH PERFORMANCE 8 CHANNEL CLASS-D POWER AMPLIFIER
High performance Class-D Professional Amplifier has up to 50W 8CH (50W×8) power output.
EMERGENCY POWER BACK UP (DC 24V) CAPABILITY
The unit operates on a DC 24V battery power supply for emergency back up without UPS.
SMPS (SWITCHING MODE POWER SUPPLY) POWER SCHEME
High efficient, light weight SMPS power system is utilized.
RATED OUTPUT POWER VIA DC BACKUP SUPPLY
Output power can be maintained as AC power when DC 24V power supplied.
POWERFUL AND DETAILED SOUND QUALITY
High S/N ratio and Low THD reproduces powerful and detailed sound.
COMPLETE PROTECTION CIRCUITS
Complete circuit protection is activated in case of amplifier overheating, output shorting, overload, over power and DC output.
OPERATION INDICATOR LED
LED display to check the operating status (AC, DC, STBY, POWER, SIG, CLIP, PROT)
BALANCED INPUT
This connection is used to ensure the lowest noise operation which eliminates the common noise from the cable.
PRIORITY INPUT
PGM is interrupted and over ridden by the Priority input, when a contact closure is received on the Priority input terminal. This is Ideal for Emergency message broadcasting applications.
SIGNAL LINK
Signals input to the CH1 can be sent to the other channels(CH2~CH8). Received signals can be output from the same channels.
