This unit allows amplifiers without direct 70V or 100V output capability to drive distributed speaker systems designed to operate at those voltages. The TP-170V is constructed of sturdy steel, and hinged on one side to allow easy access to the inside connections. For more details about the Crown TP-170V, contact Crown Customer Service at 800-342-6939 or 574-294-8200. Also, visit the Crown Audio website at Specifications Output connectors: One five-pole terminal strip per channel with touch-proof cover. Accepts up to 10 AWG terminal forks. Frequency Response: +/- 0.5 dB (20 Hz to 20 kHz). Insertion (Core) Loss: 0.41 dB max (70VAC at 50 Hz). Dimensions: 19 in (48.3 cm) wide (including hinge) 7.23 in (18.4 cm) high 1.45 in (3.7 cm) deep. Weight: 12.75 lbs (5.78 kg). ■ Features ♦ Four autoformers per panel provide four channels of Impedance matching for Constant-Voltage operation ♦ Provides 100V output in Dual mode when used with CTs 600, CTs 1200, CTs 4200 and CTs 8200 amplifiers ♦ Allows amplifiers without direct Constant-Voltage capability to be easily integrated into distributed systems ♦ Convenient hinged rack mounting allows easy access to connections A Installing the TP-170V CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with the power switch in the “off” position and all level controls turned completely down (counterclockwise). Use a standard 19-inch (48.3-cm) equipment rack (EIA RS-310B) to install the TP-170V. Connect the Grounding Strap Connect the TP-170V grounding strap to a rack rail or rack ground, and be sure the rack is grounded to an AC mains safety ground. (Test the AC mains ground to make sure it is reliable). If you are not using a rack, be sure to connect the TP-170V grounding strap to an AC mains safety ground and mount the unit in a metal box for safety. Insulate the TP-170V from the box. CAUTION: Do not remove the grounding strap or leave it unconnected. Choose Output Wire and Connectors Crown recommends using professionally constructed, high quality, two- or four-conductor, heavy gauge speaker wire and connectors. You may use terminal forks or bare wire for your output connectors. The TP-170V terminal strips accept up to 10 AWG terminal forks which fit over a #8 screw. CAUTION: Use insulated terminal forks to prevent shorting against the touch-proof cover plate. To connect TP-170V outputs, first remove the touch-proof cover plate covering the output terminal strip by removing the three screws which hold it in place. To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable and connectors. Reinstall the cover plate. Wire Your System Refer to the chart in Figure 1 to determine the proper transformer tap to use, based on the rated output power of your amplifier and the desired constant-voltage of your system. Then wire the connections as shown in the corresponding wiring diagram in Figs. 2 through 4. CAUTION: Never use shielded cable for output wiring. Figure 1.
