2.5.2 Digital Level Control (with stop)
The devices are equipped with a rotary switch per channel of the amplifier, which is setting the level of
the amplifier. The adjusting range is –90dB to 0dB. The 16 different settings of the digital switch are as
follows:
–90, –78, –66, –54, –42, –30, –24, –18, –15, –12, –9, –6, –3, –2, –1 and 0 dB.

Caution
Please keep in mind that the position of the rotary control will be detected by a microcontroller
which will then set the according level of the amplifier when it’s switched on.
The XR series is an exception: The last set level is stored in the DSP. After powering up, the
amplifier will be set to this level. Furthermore the stored level will be ignored if the rotary
control is being set to –90dB.
2.5.3 Digital Level Control (endless)
