Bogen - WMT1A Line Matching Transformer, 10k-Ohm to 600-Ohm Impedance, Telephone Paging, Music on Hold - Black

The Bogen WMT1A is a line-matching transformer engineered for impedance-matching inputs from or outputs to a 600-ohm telephone line. With a Hi-Z 10k-ohm primary impedance and a Lo-Z 600-ohm secondary impedance balanced with a center tap, the WMT1A bridges the gap between high- and low-impedance audio circuits without soldering or complex wiring. It connects telephone systems to most Bogen public address amplifiers for telephone paging applications and doubles as an output-matching transformer for feeding program material over a 600-ohm line, making it ideal for music-on-hold setups. Compatible with any amplifier featuring a 25V output terminal, the WMT1A uses an RCA connector on the Hi-Z side and screw terminals on the Lo-Z side for quick installation. The compact steel enclosure includes mounting ears for secure surface or wall mounting. Frequency response is rated at plus or minus 2 dB from 50 Hz to 20 kHz. The unit measures 2 inches wide by 2-3/8 inches high by 1-1/4 inches deep and weighs 4 ounces.

• Bidirectional 10k-Ohm to 600-Ohm Impedance Match: The WMT1A matches high-impedance (10k-ohm) to low-impedance (600-ohm) lines in either direction, providing a perfect impedance match between a 600-ohm balanced telephone line and the high-impedance AUX input of a Bogen amplifier. Compatible with any amplifier having a 25V output terminal.
• Telephone Paging and Music-on-Hold Ready: As an input-matching transformer, the WMT1A connects telephone systems to most Bogen public address amplifiers for telephone paging. As an output-matching transformer, it feeds program material over a 600-ohm telephone line for music-on-hold applications. Frequency response: plus or minus 2 dB from 50 Hz to 20 kHz.
• RCA and Screw Terminal Connections: The Hi-Z side uses a standard RCA connector for easy connection to the AUX input of a Bogen amplifier or pre-amplifier. The Lo-Z side uses a three-screw terminal strip for direct connection to the 600-ohm balanced telephone line. No soldering required — install in minutes with a standard screwdriver.
• Adapts Line-Level Signals to Mic Inputs: In addition to telephone paging and music-on-hold use, the WMT1A can adapt line-level signals from a pre-amplifier or audio source to microphone-level inputs. It can also balance an unbalanced line or provide isolation between two pieces of equipment, making it a versatile tool for commercial audio installations.
• Compact Steel Enclosure with Mounting Ears: The WMT1A is housed in a small steel enclosure measuring 2 inches wide by 2-3/8 inches high by 1-1/4 inches deep, weighing 4 ounces. Integrated mounting ears allow secure attachment to walls or equipment enclosures using two standard screws. Compact form factor fits easily in telephone equipment rooms, paging head-ends, or rack enclosures.
