Operator Manual – TRA Series Amplifiers

Typical Applications

TRA-Series amplifiers offer many output options. In this illustration, the 4-channel

amplifier is receiving two stereo signals and is driving two pairs of stereo speakers.

TRA-Series amplifiers are specifically designed to drive 70V or 100V constant voltage

(CV) lines. This illustration shows a 2-channel TRA driving two 70V CV lines. Always

make sure that the total wattage draw from all the speakers on a CV line does not exceed

the rated output of the channel to which they are connected.

Connectors & Polarity

TRA-Series amplifiers utilize two types of professional audio connectors. For the inputs

3-pin Euroblock connectors are utilized with their polarity clearly marked on the

amplifier's rear panel. Outputs are via screw terminal connectors. The polarity for these

connectors is also clearly marked on the unit's chassis.

NOTE: It is possible to simultaneously drive loads connected to the 8/4 ohm output

AND the, 70/100 volt outputs of a particular amplifier channel. However, care must be

taken to ensure that the combined load is not less that the 4 ohm maximum. If you are

unsure as to how to determine the combined load, please contact Ashly.
