AC POWER CORD INLET: Plugs into AC power receptacle. U.S., Canada and Japan Models,
100-120Vac, 50/60Hz. All other models, 220~240Vac, 50/60Hz.
FUSE: Insert a flat blade screwdriver into the fuse holder located in the bottom portion of the
AC Power Cord inlet. Carefully pry the fuse holder free from its compartment to access fuse.
(Note: For all models, replace with 250VAC, .2A slowblow type fuse.)
OUTPUT: The output of the BBE 482i can be taken from the 1/4” Phone Jack or the RCA
Jack. Both are unbalanced and are the same point electronically. This allows both outputs to
be used simultaneously, eliminating the need for a “Y” cord in the event multiple outputs are
required. The recommended single load impedance is at least 10k Ohms. If both outputs are
being used, a minimum of a 22k Ohm load per device is required. (The “load” is determined
by the input impedance of the next subsequent component in the signal chain.) The maximum
output is rated at +18dBu. The output impedance of the BBE 482i is 1 k ohms. NOTE: Actual
output level will vary due to the selected position of the BBE Process, and the actual input sig-
nal level.
INPUT: The input of the BBE 482i is an unbalanced connection. Although it can be either a
1/4” Phone Plug or an RCA Plug, it is recommended that only one input source is used. Both
jacks are the same point electronically, however, due to the input/output impedance character-
istics of most audio devices, a loss of signal may occur and/or damage to a component if both
inputs are utilized. The input impedance of the BBE 482i is 47k Ohms. The maximum signal
level is +18dBu.
CHANNEL A: These connections function the same as CHANNEL B.
WARNING! To prevent possible speaker or amplifier damage,
always power-up peripheral devices first, wait 10 seconds,
and then turn on the power amplifier. Turn off power amplifier
first, then power-down peripheral devices.
