Weber 100 Watt Stereo MASS Attenuator

100 watt Stereo MASS. 2 channel, 8 ohms. May be used on 4, 8, and 16 ohm amplifiers. Includes MASS bypass. No line out. Treble compensation built in. Employs an actual speaker motor for realistic interaction between the attenuator and the output circuit of the amp. The attenuation is continuously adjustable from zero to over -50db. By turning the speaker control to minimum (maximum attenuation), the unit may be used as a dummy load for testing or for DI use. Both channels are totally independent. Unit may be used as two separate attenuators.
