Level Meter Alternative Scales

The standard scale used on the level meters (26-segment) for the AMP1-VS and AMP1-VSA units is the Extended VU scale (see diagram

below). However, if alternative scale characteristics are selected for the level meters using the Level Meter Internal 10-Position DIP

Switch (page 20), it is recommended that a label with the appropriate scale be applied to the front panel LED bargraph level meters. See the

diagram below for scale comparison. Scale selection includes the Extended VU (standard), VU, BBC, NORDIC, DIN, and Custom

(not shown) scales. Contact Wohler Technologies for information about alternative scale labels.
