Impedance Matching Transformer
• 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
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.
