DSA 8405
4 x 500 w multichannel power amplifier for fixed install applications
- 4 x 500 W into LZ and HZ (70 V / 100 V)
- Variable Load Drive (VLD)
- Optimized for 24/7
- High efficient Class D design
- Remote Control with optional Control Module (RCM-810)
Innovative Dynacord technology, exemplary flexibility, very high output with an extremely good efficiency and integration into IRIS‑Net networks.
Each channel can be switched individually to provide 500 W at either 2 Ohms, 4 Ohms or to drive 70 Vrms or 100 Vrms loudspeaker lines directly without an output transformer. In combination with the RCM‑810 module the user can configure these amplifiers under IRIS‑Net using the Variable Load Drive (VLD) to provide any output power in the range of 100 W to 500 W per channel (1 W increments) at any load in the range of 2 Ohms ‑ 10 Ohms (0,1 Ohms increments).
The audio quality fullfills all requirements of demanding ProSound applications.
The Phoenix input connectors are electronically balanced. Phoenix connectors are also provided for the power outputs.
The POWER REMOTE connector makes the task of remote controlling the power amplifier as well as switching it on and off simple. For further remote‑supervision and –control possibilities and integration into IRIS‑Net networks, an optional remote control module (RCM‑810) is available.
