Recorder Logging, Balanced to Unbalanced

Recorder Logging

A tape recording may be desirable for evidence to prove that certain announcements or warnings were made over the paging system. The normally open contacts (terminals 16 & 17, see Figure 2-1)may be used to activate a tape recorder to record all tones and announcements that were made, without the background music in between which would consume large amounts of tape.

Balanced to Unbalanced

The balanced inputs of the AT&T PagePal may be driven by an unbalanced source. Simply connect the two wires to the + and – input terminals.

Unbalanced inputs to power amplifiers may be driven from the PagePal’s balanced output by connecting the PagePal ground (terminal 14, see Figure 2-1)to the input ground of the power amp, and the + or – output (terminal 13 and 15, see Figure 2-1)of PagePal to the “hot” input pin of the power amp. However, the output level will be 6dB less.

Connections

The PagePal provides four connectors on the unit’s back panel (see Figure 2-1).The following information describes each of the connectors and their function.

Modular Telephone Jack

This is a standard 6-pin telephone Modular type connector, located at J1 on the unit back panel. See Table 2-1for a description of each of the pins.
