Krohn Hite Impedance Matching Transformer MT56R

Description

The Krohn-Hite Model MT56R Matching Transformer is
specifically designed as an accessory to broaden the amplification
range of Krohn-Hite amplifiers, by providing increased output
current capability and a greater range of output impedance. The
Model MT56R may be used with the Model 7500 amplifiers.
The Model MT56R provides primary-to-secondary turns ratio of
10, 5, 2.5 and 1.25 to 1, selected by the 4-position LOAD
IMPEDANCE switch. When using the Model 7500 Amplifier,
which has a 200 ohm output impedance, these correspond to
matched loads of 2, 8, 32 and 128 ohms respectively. The
operating frequency range is either 30Hz to 10kHz, or 10kHz to
500kHz, selected by the FREQUENCY RANGE switch.
Input and output connections are made to multi-purpose binding
posts on the front panel and on the rear of the chassis, with
separate chassis/grounding terminals on the front panel to provide
for either floating or chassis/ground operation.

• Frequency Range: 30Hz to 500kHz
• Output Power: 75 Watts
• Maximum Current: 6.5A
• Input Voltage: 125V rms
• Matched Loads from 2 ohms to 1k ohms
