Optional Parts for Amplifier

¥ 22,200 (1 unit, around 1973)

A unit for adding a two microphone preamplifier circuit to a mixer / preamplifier 5303 or 5600 2.
The same low-noise FET circuit is used for each preamplifier.
When using, remove the panel cover and fix it.

¥ 22,200 (1 unit, around 1975)

A unit required for additional use of two high-impedance microphones to 5600-2B. Plug in 5901 to use low-impedance microphones.
As in 5190, remove the cover of the front panel and install it in the hole for the knob.

¥ 12,800 (1 unit, around 1973)

A preamplifier for magnetic phono and tape heads.
The input for 50k Ω unbalanced program such as 5600-2B can be converted to the input terminal for magnetic cartridge or high impedance tape head.
Switching from magnetic cartridge to tape head is done by jumper switching inside 5191.
The phono equalizer is a standard RIAA curve, and the tape head equalizer is equalized for speeds of 9cm/s or 19cm/s.

¥ 13,800 (1 unit, around 1973)

A preamplifier for magnetic phono.
The RIAA curve equalizer for the 5306 converts the program input for the magnetic cartridge.

¥ 15,900 (1 unit, around 1973)
¥ 13,000 (1 unit, around 1978)

Matching / bridging transformer.
When using a 6006B, 6010B b, b or 6020, you can convert the input from 5600-2B or 7124B to 15k Ω balanced bridge input or 600 Ω matching input.
Switching from bridge to matching is done by moving the jumper wire on the socket of the amplifier.
The 5195 can also be used with the 5101B to convert the standard + 10 dBm output to a 600 Ω balanced line output.
The 5195 uses a mu-metal shield case and a ham-proof winding to achieve a shielding effect of over 90 dB.

Frequency characteristics : 50 Hz to 20 kHz
Distortion rate : 1% or less (at + 20 dbm output)

¥ 22,200 (1 unit, around 1973)

Matching / bridging transformer.
Used for 5306 mixers and preamplifiers to convert 50k Ω unbalanced input to 600 Ω balanced bridge input.
The rest is the same design as the 5195.

¥ 13,800 (1 unit, around 1973)

Universal type microphone transformer.
Used for 5101B, 5600-2B, 7124B, 7126B, etc. to convert microphone input to low-impedance balanced type.
The shielding effect of 90 dB or more is obtained by the mu-metal case and the hum prevention winding.

Frequency characteristics : 30 Hz to 20 kHz
Distortion Factor : 1% or less (-55dBm)

¥ 3,100 (1 unit, around 1973)

T-shaped pad.
Attenuates the signal to make the microphone input as sensitive as the 50k Ω unbalanced program input.
Can be used for 5600-2B, etc.
