QSC Audio ADS52 user manual AD-S52T70V/100V Transformer Tap Selection, Wiring, Amplifier

Wiring

Connect the amplifier’s + and - outputs directly to the loud- speaker’s + (red) and - (black) terminals. The binding post terminals accept wire, spade terminals, or banana plugs. Use only wire connections when using the Input Cover. The terminals are spaced 0.75” (19 mm).

Maintain proper speaker and amplifier con- nection polarity throughout the entire system. All positive-marked loudspeaker terminals should be connected to positive-marked amplifier output terminals. This will provide the best possible low-frequency output from your system.

AD-S52T 70V/100V Transformer Tap Selection

AD-S52T models are equipped with a 70V/100V matching transformer for distributed audio systems. There is a trans- former tap selector switch on the rear panel for setting the power level of the loudspeaker. The switch may also be set for 8 ohm operation, bypassing the transformer com- pletely.

To select the power level, align the slot with the desired power setting number. Use a coin or flat tip screwdriver to operate the switch.

70V distributed systems: use the right side markings. Select from 3.75, 7.5, 15, or 30 watts.

100V distributed systems: use the left side markings. Select from 7.5, 15, or 30 watts. the “X” position should not be used.

NOTE! 8 ohm setting should be used for 8 ohm audio systems only. Do not use 8 ohm setting when connecting the AD-S52T loud- speaker to 70V/100V distributed audio sys- tems.
