Amplifiers
For the first 20 loudspeaker channels, we use the analog power amplifier ALTO MC250.8. To have a optimal impedance matching, we had to operate the amplifier in bridged mode in order to get a maximum power of 4 x 500 W on 8 ohms. Since our loudspeakers have 16 ohms, we finally have at least 250 W amplifier power for the first 20 loudspeaker channels.

For the loudspeaker channels 21-32 we use 6 stereo power amplifiers TA-500 (THE T.AMP) which provide 500 W on 8 ohms.
