The Protech Audio Models 98102, 98103, 98104,
98105, and 98106 Quicktrack Audio Transformers are
high quality audio transformers packaged to facilitate
quick installation. The unique transformer-direct-to­barrier construction eliminates one of the most com­mon problems encountered while using impedance
matching audio transformers. How to mount them?
This design approach saves substantial time and money,
and reduces errors in all types of installations.
Each termination point in the transformer is brought
out to a separate barrier screw. The barrier screw is
assembled with a hold down plate. In order to termi­nate a wire, the technician simply strips the wire,
places the stripped end under the corresponding hold
down plate, and tightens the screw. Each barrier screw
is clearly marked with a number. This number corre­sponds to the transformer schematic termination
point.
The Quicktrack mounting extrusion simplifies the
actual mounting of the assembly, into the
equipment rack. One machine screw set , is all that
is required to mount the assembly. The printed

board with the barrier terminal and audio trans­former, slips out of the extrusion to allow easy access
to the mounting hole. Extrusions are available in 19"
lengths.
The impedance values of the five models are:
Model 98102 = 600/600
Model 98103 = 150/600
Model 98104 = 600/10K
Model 98105 = 10K/10K
Model 98106 = 75/600
In addition, the split primary or split secondary wind­ings allow these transformers to serve well in certain
combining or splitting applications.
The specifications of each transformer are comparable
to most high quality audio transformers being manufac­tured today. Each coil assembly is wrapped in a
proprietary EMI/RFI sheilding copper tape. This tape
produces shielding performance approximately 5dB
better than other commonly used tapes.
We at Protech Audio believe these five audio trans­formers will be helpful, cost-saving tools, for the audio
technician. For additional information, or applications
