IMPORTANT SAFEGUARDS
INSTALLATION
Water and Moisture - Do not install the appliance near water:
for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. Heat - Do not install the appliance near sources of heat such as radiators, heat registers, stoves, or other appliances that produce heat. VentIlation - Situate the product so its location or position does not interfere with its proper ventilation. For example, you should not place the product on a bed, sofa, rug, or similar surface that might block the vent openings, or placed in a built-in installation, such as a bookcase or cabinet that might impede the flow of air through the ventilation openings. Wall or Ceiling Mounting - If your appliance can be mounted to a wall or ceiling, mount it only as recommended. Accessories - Do not place this product on an unstable cart, stand, tripod, bracket, or table. The product may fall, causing serious injury to a child or adult, and serious damage to the product. Use only with a cart, stand, tripod, bracket, or table recommended by the manufacturer, or sold with the product.
Any mounting of the product should follow the manufacturer’s instructions, and should use a mounting accessory recommended by the manufacturer.
USE
Power Source - Connect the appliance to a power supply only
of the type described in the operating instructions or as marked on the appliance. Power-Cord Protection - Route the power cord so that it is not likely to be walked on or pinched by having objects placed on it, paying particular attention to the plugs, receptacles, and the point where the cord exits from the appliance. Grounding or Polarization - Do not defeat the grounding or polarization feature of the AC power cord. If your AC receptacle will not accept the power cord plug, contact your electrician to install a proper AC receptacle. When not in use - Unplug the power cord of the appliance from the outlet when left unused for a long period of time.To disconnect the cord, pull it out by grasping the plug. Never pull the plug out by the cord. AC Receptacle - Check to make sure that the AC receptacle
holds the power cord plug firmly and securely. If the power cord plug is loose, contact your electrician to replace the defective and unsafe AC Foreign Objects - Be careful that foreign objects and liquids do not enter the enclosure through openings. Cleaning - unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
SERVICE
Unplug the appliance from the wall outlet and consult qualified service personnel when:
• the power cord or the plug has been damaged.
• a solid object or liquid has fallen into the cabinet.
• the appliance has been exposed to rain or moisture.
• the appliance does not appear to operate normally or exhibits a marked change in performance.
• the appliance has been dropped, or the enclosure damaged. Do not attempt to service the appliance beyond that described in the operating instructions. For all other servicing, refer to qualified service personnel only.

THE BBE PROCESS—"WHAT IT IS"
Loudspeakers have difficulty working with the electronic signals supplied by an amplifier. These difficulties cause such major phase and amplitude distortion that the sound reproduced by speaker differs significantly from the sound produced by the original source.
In the past, these problems proved unsolvable and were thus delegated to a position of secondary importance in audio system design. However, phase and amplitude integrity is essential to accurate sound reproduction. Research shows that the information which the listener translates into the recognizable characteristics of a live performance are intimately tied into complex time and amplitude relationships between the fundamental and harmonic components of a given musical note or sound. These relationships define a sound's “sound”.
When these complex relationships pass through a speaker, the proper order is lost. The higher frequencies are delayed. A lower frequency may reach the listener's ear first or perhaps simultaneously with that of a higher frequency. In some cases, the fundamental components may be so time-shifted that they reach the listener's ear ahead of some or all of the harmonic components.
This change in the phase and amplitude relationship on the harmonic and fundamental frequencies is technically called “envelope distortion.” The listener perceives this loss of sound integrity in the reproduced sound as "muddy" and “smeared.” In the extreme, it can become difficult to tell the difference between musical instruments, for example, an oboe and a clarinet.
BBE Sound, Inc. conducted extensive studies of numerous speaker systems over a ten year period. With this knowledge, it became possible to identify the characteristics of an ideal speaker and to distill the corrections necessary to return the fundamental and harmonic frequency structures to their correct order. While there are differences among various speaker designs in the magnitude of their correction, the overall pattern of correction needed is remarkably consistent.

FRONT PANEL
1/4” INPUT CONNECTOR
The 1/4” input connector of the DI-400 is unbalanced. The 1/4” input is designed for running instrument cables directly into the DI-400.
1/4” THRU CONNECTOR
This 1/4“ connector is wired in parallel to the Input connector and is used for continuing the connection to the instrument amplifier.
PAD PUSH BUTTON
Push in to activate “-15dB” pad.
IN/OUT PUSH BUTTON
Engages the Sonic Maximizer Process. When the switch is pushed in, the BBE Process is on. When the switch is up, the BBE Process is off.
LED STATUS PHASE PUSH BUTTON
Push in to reverse phase.
“RED” = power on,
BBE off/out, “GREEN”
= power on, BBE on/in.
LED not illuminated =
power off.
LOW CONTOUR CONTROL
Regulates the amount of phase corrected bass frequencies.
PROCESS CONTROL
Regulates the amount of phase correction.
POWER SWITCH
The Sonic Maximizer LEDs will illuminate when the power is on.
5
REAR PANEL
XLR OUTPUT CONNECTOR
The XLR output of the DI-400 is balanced. The XLR output is used for running from the DI-400 directly to the input of a mixing console.
FUSE
Replace as needed with specified size and type.
6
1/4” UN-BALANCED INPUT CONNECTOR
The 1/4” input connector is wired in parallel with the front panel input and thru jacks.
XLR Pin configuration: Pin 1 = Ground, Pin 2 = Positive and Pin 3 = Negative.
GROUND LIFT PUSH BUTTON
When in the “lift” position (in) Pin 1 of the balanced XLR output (ground) is disconnected.

SERVICE
We recommend that if at all possible, a BBE DI-400 which requires service be sent to our facility in Huntington Beach, California. We request that a “RETURN AUTHORIZATION” be issued by the dealer from whom you purchased the unit. If this is not possible, call BBE Sound, Inc. directly at (800) 233-8346, extension 116 to obtain a “RETURN AUTHORIZATION.” Include a copy of the bill of sale with the unit when it is shipped to BBE Sound, Inc. so that the service can be expedited.
Maintenance of the BBE DI-400 is limited to proper cleaning of the unit with mild household cleaner such as Formula 409™ or Windex™. The chassis is steel , the casing is an aluminum extrusion. Both are finished with a durable polyurethane paint.
There are no user replaceable parts and the unit should not be opened for any reason unless you are a qualified technician. Calibration should be performed if parts are
As the repair turnaround time is minimal, we request that the unit be sent to BBE Sound, Inc. We also need to add reliability data to our files so that future revision may be undertaken, if necessary, to improve the product.
If unit has been purchased outside the US, please contact your national distributor
.
MAINTENANCE
replaced or if a performance check-out indicates a problem with calibration. Long term use has shown that over the life of this unit there is little or no drift of the components in the BBE DI-400 which would cause a change in calibration.
