2 DESCRIPTION
The SIMAX BA Series amplifiers are specially designed for professional installations where
eficiency is a relevant factor. Thanks to its class D amplification technology and its switched-mode
power supply achieves a power consumption efficiency of 85%, dissipating less heat and
occupying only one height of a 19" rack.
The BA series has two types of two channels amplifiers: 250 W rms (BA-2250) and 500 W
rms (BA-2500), that are protected against short circuit and overload. Thanks to its flexible design it
allows both 100V high impedance and low impedance stereo 8 ohms (BA-2250) or 4 ohms (BA-
2500) public address systems. Each channel integrates a high-pass filter and an automatic
standby for noise gate, whose operation can be activated from the rear panel.

4. 250W rms (BA-2250) and 500 W rms (BA-2500) power rating per channel
5. Two independent output channels 8Ω / 100V (BA-2250) and 4Ω / 100V (BA-2500)
6. XLR balanced input through phoenix connector
7. Independent gain control per channel
8. High pass filter per channel
9. Automatic standby by integrated noise gate to save energy
10. Independent channel indicators for input and output protection
11. Short-circuit, overload and overheat protection
