Night Ringer Connection
Either a standard analog telephone ring signal (90–105V AC, 20–30 Hz) or an external contact closure activates
the night ringer function of the amplifier. To activate the night ringer using standard analog telephone ring, connect
the analog station’s tip lead to the TEL RING “T” terminal, and connect the ring lead to the “R” terminal. If using an
external contact closure, connect the closure pair across the CONTACT RING and GND terminals. The night ringer
follows the cadence of the activating signal.
Bridging Inputs
Bridging inputs (see Figure 6) are provided to ease interconnection of multiple TPU Series amplifiers. Bridging per -
mits two amplifiers to be used in tandem with one another to increase the total output power of the system, thereby
permitting additional speakers to be added. For example, when two 600-watt amplifiers are bridged, the total output
capacity of the combined TPU600-G2 system is 1200 watts. However, bridging does not increase the size of the
load a TPU600-G2 can individually handle . Once bridged, each amplifier will amplify the inputs present on both
amplifiers. The level control of a particular input on an amplifier will control the volume of this signal on both ampli -
fiers. The cable used to bridge amplifier inputs should not exceed 20 feet in length.
NOTE: Any combination of TPU series amplifiers can be bridged together to achieve a desired power output level;
however, you can only bridge together a maximum of two (2) TPU-series amplifier units.
