lies processing units). Such sources can be balanced or unbalanced —
this is no problem for the 160XT.
Microphones and bass guitars, like guitars, typically have low-level out¬
puts.
Instruments like keyboards typically produce a line-level signal and can
be connected directly from the instrument’s output to the 160XT’s input.
Patch bay
In the studio, the 160XT may be connected to a patch bay to allow it to be
used anywhere in the studio system. Do not ground Pin 2 (or 3) of the
XLR-type output connector (distortion can result). If your studio is not fully
balanced, you should leave pin 2 disconnected or use the %“ phone jack
output, which is single-ended. Another option is to install an output trans¬
former, which will allow grounding of either pin 2 or 3 of the XLR-type out¬
put (see page 24).
Sound reinforcement:
To compress a live mix or to protect loudspeakers, connect the 160XT be-
v : tween the source (mixing board or distribution amp) and the power
amp(s). If multi-way loudspeakers with low-level electronic crossovers are
used, the 160XT(s) should go after the crossover(s). For a stereo system,
you can separately stereo couple the two high band crossovers, low band
crossovers, etc. (see page 16). If limitations require that you use a single
160XT before a crossover, adding an equalizer to the side chain may pro¬
vide some additional protection to your high frequency component (see
“Speaker Protection,” page 12).
Installation considerations _
Mounting the 160XT in a Rack (OPTIONAL)
Mount the 160XT in a 1U rack space (1.75 inches, 4.45 cm).
Mounting the unit directly over large heat-producing devices (such as a
vacuum-tube power amplifier) may shorten component life and is not rec¬
ommended. Ambient temperatures should not exceed 113°F (45°C) when
equipment is powered.
Caution: Never remove the cover. There are no user-serviceable parts in¬
side, and you run the risk of an electric shock.
