Function |
Matrix Amplifier for
conversion from L/R to M/S stereo or
M/S to L/R stereo |
|
|
Convertion Levels |
L/R to M/S conversion:
Mono Signal on L and R results in:
- 6 dB, 0 dB, or + 6 dB on the M output
Phase reversed Mono Signal on L and R
results in
- 6 dB, 0 dB, or + 6 dB on the M output
M/S to L/R conversion:
0 dB on M results in
- 6 dB, 0 dB, or + 6 dB on the L and R outputs in phase
0 dB on S results in
- 6 dB, 0 dB, or + 6 dB on the L and R outputs out of phase

Channel Match |
left channel = M, right channel = S |

*) The standard supply current is the supply current under realitic operation conditions. If the outputs are loaded with the minium load resistors and the level is at + 30 dBu, the supply current increases by 30 mA per output. The standard supply current shuold be used to calculate the necessary power supply capacity of a system. |
