MAXIMUM RELIABILITY UNDER THE MOST DIFFICULT CONDITIONS

Amplifier 250/300 W and 2 x 250/300 W

Class D technology

Description 

1-channel and 2-channel output stages are provided for stationary installation in the ELA system (DS-6, MDK, MF, etc.) of Neumann Elektronik.

The amplifier corresponds to class D.
This switching concept guarantees a high efficiency factor with little heat generation.

The amplifiers deliver an output power rating of 1 x 250 / 300 watts or 2 x 250 / 300 watts at an operating voltage of 230 / 115 VAC or 48...60 VDC.

- High efficiency factor
- Negligible heat generation
- No active ventilation required
- Low depth (important for cabinet mounting)
- Front panel LEDs for all signal and operating modes: Power ON, DC, Signal OK, Clipping, Fault
- Front panel access to volume, bass and treble controls (screwdriver slotted)
- Switchable input sensitivity
- Potential free amp connection
- Indication: Fuse failure, overload, overtemperature
- Short-circuit, overload protection
- 230 V / 115 VAC input voltage (switchable)
- 48 V / 60 Vdc input voltage
- Amplifier protected against open and short circuits
- 100 V and 50 V output, ungrounded
- Inputs symmetrical to transformer
- All wiring with plug and socket connector, with removable screw connections
