Transformers Speaker Impedance Matching Models: T72510 T725 T725 & T72510 Line Impedance Matching Models: TL100, TL600, WMT1A, & WMT1AS TL100/TL600 WMT1A, WMT1AS T725, T72510 WMT1A Description The Bogen Models T725 and T72510 transformers The Bogen WMT1A transformer is designed especially are speaker-matching transformers that allow an for impedance-matching inputs from, or outputs to, 8-ohm speaker to be connected to 70V or 25V ampli- a 600-ohm line. It has a Hi-Z, 10k-ohm primary imped- fier outputs. An 8-ohm secondary connects to the ance and a Lo-Z, 600-ohm secondary impedance speaker and the multi-tap primary connects to the balanced with a center tap. 70V or 25V amplifier output. As an input-matching transformer, it may be used to The T725 can be tapped at 4, 2, 1, 1/2, 1/4, and 1/8 connect telephone systems to most Bogen public watts, while the T72510 can be tapped at 10, 5, 2-1/2, address amplifiers for telephone paging. It also 1-1/4, and 5/8 watts. All wires are easily accessible. functions as an output-matching transformer in feeding program material over a 600-ohm telephone line (typically formusic-on-hol applications). It is TL100, TL600 compatible with any amplifier having a 25V output The Bogen Models TL100 and TL600 line impedance- terminal. matching transformers are compact, plug-in units specially designed for use with power amplifiers. WMT1AS The TL100 provides a balanced 1:1 input match and The WMT1AS has all the features and functions of isolation its primary impedance will be the same the WMT1A, but can also adapt speaker-level signals value as total termination of the input impedance to (25V/70V systems) to a level suitable for the AUX the amplifier(s). input of an amplifier. Model TL600 impedance matches the output of a 600- ohm telephone line to a Bogen power amplifier input. Features T725 and T72510 WMT1A Allows an 8-ohm speaker to connect to 70V Hi-Z, 10k-ohm primary impedance or 25V amplifier outputs Lo-Z, 600-ohm secondary impedance, balanced T725 Power Taps: 4, 2, 1, 1/2, 1/4, 1/8 watts with center tap T72510 Power Taps: 10, 5, 2-1/2, 1-1/4, 5/8 watts Matches high-to-low impedance or low-to-high impedance Easily-accessed, stripped and tinned wire terminations Adapts line-level signals to microphone inputs Small, compact, and cost-effective RCA connector for Hi-Z side Screw terminals for Lo-Z side TL100 and TL600 Small steel enclosure with mounting ears allows easy mounting Provides balanced, isolated, 1:1 or 600-ohm input No wiring or soldering required for power amplifiers May be used to provide a 600-ohm output from Transformer connections terminated in a keyed a Bogen mixer/pre-amplifier nine-pin miniature plug Compact, plug-in design WMT1AS Internal mumetal shielding All features and functions of the WMT1A, but can also adapt speaker-level signals to the AUX input level of an amplifier Specifications subject to change without notice. 2002 Bogen Communications.
