Db2 - Drive Bus Master Output & Drive Section
Signals enter the Db2 either through the electrically balanced
input jack or via the internal TouchPatch bus. The bus overload
LED monitors the TouchPatch bus for clipping.
The drive attenuator controls the signal level presented to the
high-voltage solid-state amplifier and dual vacuum tube output
driver sections. The drive threshold LED indicates the level of
drive. The three-position output switch selects between solid-state,
tube or bypass.
The final gain control determines the final output level, which is
available on the XLR jack at +4dBu, and on 1/4” TRS at -10dBV.
The final output level is monitored by the VU meter.
