TL100 ,TL600
The Bogen Models TL100 and TL600 transformers
are compact plug-in units especially designed for use
with power amplifiers.
The TL100 provides a balanced one-to-one 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 matches the output of a 600-ohm telephone line to a Bogen power amplifier input.
WMT1A
The Bogen Model WMT1A transformer is designed
especially for matching inputs from, or outputs to, a
600-ohm line.
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 for
"music-on-hold". It is compatible with any amplifier
having a 25V output terminal.
WMT1A
Frequency Response: 50 Hz to 20 kHz ±2 dB
Sensitivity: Less than 0.1V across 600-
ohm line required for full
output power from average
amplifier. Maximum level
+20 dBm
Output: Approx. 1.73V output when
connected across 25V output tap or WMT1A Hi-Z
output connection on a
Bogen amplifier.
Dimensions: 2-3/8" H x 2" W x 1-1/4" D
Shipping Weight: 1 lb.
TL100 & TL600

600-ohm telephone line to
input of power amplifier
Frequency Response: TL100 – 20 Hz to 15 kHz,
±2 dB
TL600 – 20 Hz to 20 kHz,
±1 dB
Hum Reduction: Mumetal shielding

WMT1A
The line-matching transformer shall be a Bogen
Model WMT1A, or equivalent, capable of matching
either inputs from, or outputs to, a 600-ohm line. It
shall provide a perfect impedance match between a
600-ohm balanced line and the high-impedance input
of an amplifier, or the 25V output of an amplifier.
Frequency response shall be ±2 dB from 50 Hz to 20
kHz. Less than 0.1 volt across 600-ohm line shall be
required for full output power from an average amplifier (maximum level, +20 dBm). Output shall be
approximately 1.73 volts when connected across the
25V output tap or WMT1A Hi-Z output connection
of a Bogen amplifier.
Line input or output connections from the 600-ohm
line shall be made to a three-screw terminal strip.
Connection to the auxiliary input of an amplifier shall
be by means of a shielded cable terminated in a
phono plug. Provisions shall be included to connect
the unit to a microphone input.The mounting bracket shall provide for the transformer to be mounted
by means of two steel screws.The unit shall measure
2-3/8" H x 2" W x 1-1/4" D and the shipping weight
shall be 1 lb.
TL100
The matching transformer shall be a Bogen Model
TL100, or equivalent, and shall provide a balanced
one-to-one input for matching and isolation.The primary impedance shall be the same value as the total
termination of the input impedance to the amplifier(s). The frequency response shall pass frequencies
within ±2 dB from 20 Hz to 15 kHz. The unit shall
incorporate mumetal shielding for hum reduction.
The transformer connections shall terminate in a
keyed nine-pin miniature plug, which shall fit into a
matching nine-pin receptacle. The transformer shall
be cylindrical in shape with a 1" diameter and the
overall length (including pins) shall not exceed 2".
TL600
The line transformer shall be a Bogen Model TL600,
or equivalent, and shall match a balanced 600-ohm
zero level transmission line, or provide a 600-ohm
output from a pre-amplifier. The secondary impedance shall be 10,000 ohms. The overall frequency
response shall pass frequencies within ±1 dB from 20
Hz to 20 kHz. The unit shall incorporate mumetal
shielding for hum reduction. The transformer connections shall terminate in a keyed nine-pin miniature
plug, which shall fit into a matching nine-pin female
receptacle. The transformer shall be cylindrical in
shape, with a 1" diameter and the overall length
(including pins) shall not exceed 2".
