2 X 120 Watts with 70V/100V outputs
2 X 150/90 Watts with 4/8-ohm loads
Euroblock inputs and outputs
Separate gain controls for each channel
Signal, clipping and thermal interruption indicators
Short-circuit and open-circuit protection
Overview:
The DN-474A 2x2-Channel Dual-Impedance Ampli er is designed for contractor/install market applications which specify installed speaker systems requiring 70V/100V inputs, and has the added exibility of handling loimpedance loads (4Ω/8Ω). The ampli er is split so that two channels handle the lo-impedance speakers, while two channels take care of the 70V/100V speaker runs. This very versatile, one rack space ampli er has built-in short circuit protection - and LED indicators for signal present, clipping status and thermal interruption on the front panel. Engineered for the distribution of multiple 70V/100V speaker systems over long cable runs - such as in-ceiling speakers, surface-mount speakers and paging horns, and also for shorter runs to lo-impedance speakers.
