70-Volt/100 Watt Line (320-1032) Connections Faxback Doc. # 16225 Transformer NOTE: The Transformer may be used with amplifiers that have 8- or 16-ohm speaker outputs, but the efficiency of the amplifier will be reduced - you won't get the full power of the amplifier. The Transformer may be used with amplifiers that have up to 100 watts of continuous output power per channel. Also, one Transformer may be used for each channel of a stereo PA amplifier or home stereo amplifier/receiver. 1. Connect the 4-ohm terminal of the Transformer to the speaker terminal of your amplifier. Keep the Transformer as close to the amplifier as possible, and use large gauge wire for better performance. 2. Connect the 70-volt output of the Transformer to the speaker line. Be sure to use the proper gauge wire, as listed below, for the length of wire and amount of power you plan to use. 50 feet (15m) or less wire with 50 watts or less power = 18 gauge wire 50 feet (15m) or more wire and/or 60 watts or more power = 16 gauge wire NOTE: A lower wire number means larger size wire. 3. Connect the speakers to the 70-volt speaker line using a 70-volt/10 watt speaker transformer (32-1031) for each speaker. Be sure to use the correct wattage and impedance taps on each speaker transformer. See the instructions supplied with the speaker transformer (32-1031). The same wattage tap should be used on all speaker transformers and the total wattage must not exceed the maximum power of the amplifier. For example, if you have 10 speakers and are using the 5-watt tap, your amplifier must deliver at least 50 watts (10 speakers x 5 watts). The impedance tap used on each speaker transformer must match the impedance of the individual speaker. CAUTION: Be careful not to accidentally connect together the + and - wires of the 70-volt speaker line. (ALL-07/28/95)
