T725

Description T725, T72510

The Bogen Models T725 and T72510 transformers are speaker-matching transformers that allow an

8-ohm speaker to be connected to 70V or 25V amplifier outputs. An 8-ohm secondary connects to the speaker and the multi-tap primary connects to the

70V or 25V amplifier output.

The T725 can be tapped at 4, 2, 1, 1/2, 1/4, and 1/8 watts, while the T72510 can be tapped at 10, 5, 2-1/2,

1-1/4, and 5/8 watts. All wires are easily accessible.

TL100, TL600

The Bogen Models TL100 and TL600 line impedancematching transformers are compact, plug-in units specially designed for use with power amplifiers.

The TL100 provides a balanced 1:1 input match and isolation; its primary impedance will be the same value as total termination of the input impedance to the amplifier(s).

Model TL600 impedance matches the output of a 600ohm telephone line to a Bogen power amplifier input.

WMT1A

The Bogen WMT1A transformer is designed especially for impedance-matching inputs from, or outputs to, a 600-ohm line. It has a Hi-Z, 10k-ohm primary impedance and a Lo-Z, 600-ohm secondary impedance balanced with a center tap.

As an input-matching transformer, it may be used to connect telephone systems to most Bogen public address amplifiers for telephone paging. It also functions as an output-matching transformer in feeding program material over a 600-ohm telephone line (typically for "music-on-hold" applications). It is compatible with any amplifier having a 25V output terminal.

WMT1AS

The WMT1AS has all the features and functions of the WMT1A, but can also adapt speaker-level signals

(25V/70V systems) to a level suitable for the AUX input of an amplifier.
