USER MANUAL
▲

Congratulations on the purchase of your
BBE DI-10 direct box!
The BBE DI-10 is an active direct box used for converting line out and
speaker out signals to balanced and unbalanced signals. The user also
has the ability to select between two frequency responses (flat, or
speaker compensated). Using the outputs from the DI-10, the user can
direct feed to a mixer, recorder, or sound reinforcement system.
The features that make up the BBE DI-10 are:
1. Speaker thru and Speaker input jacks.
2. 1/4” phone jack for line level signal input and output.
3. XLR jack for mic level, balanced output.
4. Filter switch to operate the speaker simulating filter.
5. Tri-mode powering for three different modes of powering:
a) internal 9V battery,
b) 9VDC external power source, and
c) 48V phantom power source through the XLR connector.
6. Tri-mode power scanning feature which scans the three power
sources and uses only the highest source of power and shuts off the
other power sources.

FRONT PANEL CONTROLS
1. D.C. INLET: This jack is for connecting the 9 VDC power source. The 9
VDC power plug must be of the type where the positive voltage is on the outer
ring.
2. FILTER SWITCH: This switch is used to operate the speaker simulating fil-
ter. When the filter is off, system frequency response is flat. When the filter is
on, a 4th order filter network is activated and the system frequency response is
6dB down at 4kHz.
3. LINE OUT: This 1/4” phone jack provides an unbalanced line level output.
REAR PANEL CONNECTIONS
4. SPEAKER THRU AND SPEAKER INPUT: These are 1/4” mono phone
jacks. When using an amplifier, the output from the power amp section connects
to the ‘speaker input’ jack while the amplifier speakers connect to the ‘speaker
through’ jack.
CAUTION: Never operate an amplifier featuring a tube power stage without a
connection to a speaker or sufficient power resistor.
5. LINE INPUT: This is a 1/4” mono phone jack for line level signal insertion.
NOTE: Connecting a 1/4” male plug to either the speaker in jack or the line in
jack will activate the internal 9 volt battery.
6. BALANCED OUT: This XLR jack provides a mic level balanced output. Pin
2 being the ‘hot’ pin. The DI-10 can also be phantom powered through this jack.
NOTE: This unit may be powered by three (3) different modes.
1. Internal 9 volt battery.
2. 9 VDC external power source.
3. 48v phantom power source.
