SETUP
Before mounting your NANOAMP in a rack, remove the top cover (4 upper side
screws) and set the preamp gain DIP switches (S5, 6, c and d) to match the
nominal expected input level for the HI gain position of the panel switches. Set
the LO preamp gain with the DIP rocker switches (S5, 6, a and d) to the highest
level that does not permit input circuits PEAK indications. Hot mics will require
lower gains (20 – 30 dB) while low output mics will require higher gain settings
(40 – 60 dB). Also, select line (+4 dBm) or mic level (-50 dBm) outputs with
jumper plugs P1 or P2.
MOUNTING
NANOAMPS may be rack mounted one, two, or three across in a standard EIA
19” rack and will require only 1 ¾” of vertical space. Rack mount kit P/N20604-
501mounts a single unit, P/N20604-502 mounts two units and P/N20604-503
mounts three units. Each kit provides a different size pair of rack mounting
brackets and one or two horizontal joiner plates, P/N20580-1, each with four 4-40
X 5/16” oval head screws. The joiner plates mount into tapped holes on the
bottom of two side-by-side units, using the supplied screws, while the rack mount
brackets mount under the existing 6-32 cover securing screws in the front sides
of the units.
Single desk mounting kits consist of a pair of angled base plates that mount
under the lower front and rear cover screws of a single unit, to raise and to tilt it
for easy use. In addition, one or more sets of vertical stacking plates, mounting
to the upper front and rear cover screws of the bottom unit, allow multiple units to
be stacked. Several units can be desk mounted side-by-side and even stacked
side-by-side using horizontal joiner kits together with mounting base and stacker
kits. P/N20617-501 is the angled base kit. P/N20617-502 is the base plus one
stacker kit (two high). P/N20617-503 is the base plus two stackers (three high).
P/N20617-504 is a horizontal joiner kit.
