Type 85
Frequently Asked
Questions
Q: How do you hook up a Type 85?
A: The diagrams on the next two pages show
you the two most common ways to connect
your
Type 85.
Q. I have just a guitar (or other signal sou
rce)
and no amplifie
r. How do I hook it up to the
Type 85?
A. All signal sou
rces must go to the “INST.” jack
because inserting a plug into the “INST” jack
tu
rns the TYPE 85 on. The “AMP.” jack is simply
connected in parallel with the “INST” jack but it
does not operate the power switch.
Q. How do you use the “PICKUP-SPEAKER”
switch?
A. Use the “SPEAKER” position when the TYPE
85 is connected to the speaker output of an
amplifier and the “PICKUP” for all other sou
rces
including p
reamp outputs.
Q.
How many watts can the TYPE 85 handle?
A. The TYPE 85 is so well p
rotected it can
handle the full output of any amp without
damage. In “SPEAKER” mode the TYPE 85 will
distort at the equivalent of 1,700 watts into 8
ohms.
Q. How does the TYPE 85 use Phantom
power?
A. If your mic
rophone input has 48 volt Phantom
Powe
r, the TYPE 85 will automatically switch off
its battery and use the phantom. The TYPE 85
will operate with phantom voltages as low as
24 volts but you will need to
remove its internal
batter
y.
Q. How many hours will the TYPE 85 battery
last?
A.
A fresh alkaline 9V battery will run the Type 85
for 400 hours. That
’s 2 months running 8 hours
a day but only 2 weeks running all the time so
it
’s best to turn the TYPE 85 off when not in use.
Q. How do I tu
rn the TYPE 85 off?
A. Unplugging the plug f
rom the TYPE 85
“INS
T.” jack turns off the battery. Unplugging
the “INS
T.” input does not turn off the TYPE
85 when it
’s running on Phantom power but it
shorts the input to g
round to reduce noise.
Q. I have hum or buzz. What should I do?
A. Try both positions of the “GND.” switch. If you
are using an amplifier, try different positions on
it
’s grounding switch. Walk around the stage or
room with your instrument and see if the buzz is
worse near other equipment or lights. If it is, you
can g
round them or unplug their power cords if
they a
re not in use. If the TYPE 85 is sitting on
or near another piece of elect
ronics equipment,
move the TYPE 85 to see if a very st
rong hum
field is penetrating the TYPE 85 inte
rnal shields.
Power amplifiers, light dimmers, TV sets and
video monitors can generate especially st
rong
fields.
