Yamaha IM8-24 Manual Do Utilizador

Specifications

 Owner’s Manual

All faders are nominal when measured. (The nominal position is 10 dB lower than the maximum position.)
Output impedance of signal generator: 150 ohms
* IM8-40: 1-40, IM8-32: 1-32, IM8-24: 1-24

Where 0 dBu = 0.775 Vrms and 0 dBV = 1 Vrms
* Sensitivity is the lowest level that will produce an output of +4dB (1.23 V), or the nominal output level when the unit is set to the maximum level. (All faders 

and level controls are at their maximum positions.)

MONO CH INPUT*

80 Hz, 12 dB/oct
