SPECIAL THANKS
Dear Valued Customer,
Thank you for choosing Diamond Audio D3 speakers. These speakers represent the latest advances in
acoustic technology, and like all Diamond Audio products, are hand built and tested using the highest
grade components and state of the art techniques. When installed properly, they will provide many
years of accurate sound reproduction.

permanent hearing loss. This high performance speaker system can exceed that level, so please
exercise restraint in its operation in order to preserve your ability to enjoy its delity in the future.
Because of their exible installation possibilities, please consider having your new speakers
professionally installed by an authorized Diamond Audio dealer. This will assure a clean and efcient
installation, and extend your one year warranty to three years.

On-board Crossovers
Each D3 coaxial features an on-board 12 dB/octave crossover and tweeter protection to ensure
absolute delity and protection during audio reproduction.
Standard Connection
D3 integrated systems are shipped congured for a single channel per speaker. Simply connect the
speaker wire from the source to the exposed positive and negative terminals on the speaker.
Bi-amp Connection
An exclusive feature of the D3 integrated systems is the option to power the tweeter and mid-bass
driver separately. This feature is called Bi-amping and all D3 coaxials can be bi-amped except D343i.
This ability allows for external active lter, phase, and time alignment for each of the drivers independently. To bi-amp the speaker, remove the two jumper leads from the tweeter terminals on the speaker
and connect separate power to the woofer and tweeter terminals.

Crossover Programming
Each D3 component set comes with a pair of model specic programmable crossovers. Under the cover
there is a jumper marked “TWEETER” + 2dB, 0 or - 2dB. Tweeter attenuation can be achieved by moving
the jumper to the appropriate position. The 0dB position has no attenuation effect on the tweeter.
RAF Outputs
Each D3 component crossover has a third set of outputs marked “RAF”. This stands for Rear Acoustic
Fill. This output can be used to power an additional speaker off the same channel without affecting
the impedance load on the source unit. This output provides 15-20% of the total power to the extra
speaker and is unltered or full range.
