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.

For your protection, please read these safety instructions completely before operating the appliance, and keep this manual for future reference.

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.

The BBE Process is so unique that 42 patents have been awarded by the U.S. Patent Office.

THE BBE PROCESS—"WHAT IT IS"

4

LOW CONTOUR CONTROL

Regulates the amount of phase corrected bass frequencies.

PROCESS CONTROL

Regulates the amount of phase correction.

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.

PAD PUSH BUTTON

Push in to activate “-15dB” pad.

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.

FRONT PANEL

5

POWER SWITCH

The Sonic Maximizer LEDs will illuminate when the power is on.

PHASE PUSH BUTTON

Push in to reverse phase.

LED STATUS

“RED” = power on, BBE off/out, “GREEN” = power on, BBE on/in. LED not illuminated = power off.

REAR PANEL

FUSE

Replace as needed with specified size and type.

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.

XLR Pin configuration: Pin 1 = Ground, Pin 2 = Positive and Pin 3 = Negative.

1/4” UN-BALANCED INPUT CONNECTOR

The 1/4” input connector is wired in parallel with the front panel input and thru jacks.

GROUND LIFT PUSH BUTTON

When in the “lift” position (in) Pin 1 of the balanced XLR output (ground) is disconnected.

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.

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.

SERVICE

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

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.

MAINTENANCE

9

Warranty registration of the unit to BBE Sound, Inc. is not necessary. It is strongly recommended that you retain a copy of the bill of sale for future reference.

IT IS THE SOLE RESPONSIBILITY OF THE END USER TO PROVIDE THE BILL OF SALE OR OTHER MEANS OF PROOF OF PURCHASE TO VALIDATE THE WARRANTY IF WARRANTY SERVICE IS REQUESTED.

The BBE

DI-400

is warranted against defects in material and workmanship for a period of five (5) years from date of purchase from BBE Sound Inc. or from an authorized dealer. During this period, we will repair units free of charge providing that they are shipped prepaid to:

BBE Sound, Inc., 5381 Production Drive, Huntington Beach, CA 92649.

We will pay return UPS shipping charges within the USA. All charges related to non-UPS shipping, including customs clearance, will be billed. The warranty will be honored for the longer of either 90 days from the date of any service or the remainder of the original 5 Year factory warranty.

This warranty will be consider null and void by BBE Sound, Inc. if any of the following is found:

1. The equipment has been physically damaged.

2. The equipment shows signs of abuse.

3. The equipment has been electrically damaged by improper connection or attempted repair by the customer or a third party.

4. The equipment has been modified without authorization.

5. The bill of sales indicates that the purchase date of the equipment is not within the warranty period.

All non-warranty repairs are warranted for a period of 90 days from the date of service.
