Product Overview

50W x 8 Channel Digital Commercial Power Amplifier

The DPA-50E is a 50 W×8CH(100V, 70V) multichannel amplifier which outputs 60 W×8CH(4 Ω) and 30 W×8CH(8 Ω). In this way, the DPA-50E can both be used in professional and commercial audio. 

DPA-50E is essential to build distributed control system effectively with NPX system of InterM. Designed not only for smaller venues for individual uses but also for larger venues such as hotels, training centres, schools and conference halls as it can broadcast different sound sources to different zones and control separately by channels.

Applications

Features

  • Signal Link function for multi input: With the Signal Link Switch displayed on the left side, send sound sources input to CH 1 to linked channels at the same time. For instance, switch on CH 2 and CH 1 input sound source is output to CH 3 simultaneously. Use the Signal Link function to utilize DPA-50E as you wish. ( Channels that are switched off output inserted sound sources to corresponding channels)
  • Secure operation through AC/DC dual power: DPA-50E is AC/DC dual powered and is DC 24 V provided with the battery when urgent situation such as blackout occurs. DC power is emergency power that operates regardless of ON/OFF of the power switch. It is automatically switched to AC power even when DC power is operating if AC power is working in order.
  • Priority Function: Automatic emergency broadcasting is available using priority function of DPA-50E in emergency situations. When contact closure is inserted to PRIORITY terminal on the rear panel, signals input to the PRIORITY terminal are output before the ones entered to PGM INPUT terminal. For instance, PGM INPUT of CH 7 is muted and sound sources input to the PRIORITY audio terminal are broadcasted when the contact closure is inserted to the PRIORITY terminal of CH 7.  PGM : Programmable
  • LED Indicators: The backlit LED enables to monitor AC/DC power, STBY status, SIG(-30 dB) output level of each channel, Clip and Protect status. Also, with the volumes of each channel on the front panel, separate volume control is possible.
  • Stability guaranteed with perfect protection circuit: Stability of the device is guaranteed with OVP(Over-Voltage Protection) function which perceives and blocks when in/output voltage is higher or lower than the settled voltage range, UVP(Under-Voltage Protection) and overcurrent protection function.
