In 1980, two units were priced at 500,000 yen, and although they are 40 years old, they have a slide controller on the control panel, and they are high performance EQs without any buzzing.
Simic had a 24-input studio mixer 408AV-03 at that time, priced at 1,040,000 yen.
EQA-27 has amplification = 0dB, distortion reference level 0,1% or less, maximum output level 0,3% or less, f gain 20 to 20kHz ±0,5dB.
Inspected, serviced and adjusted.
However, if you are going to use this equipment for home use, please do not use this kind of connection. However, if this equipment is to be used in a home environment, it should never be connected in this way, and should be connected to the accessory circuit of a preamplifier or pre-main (few devices have terminals for connection), or to a tape monitor circuit, and used as a source (EQ cancel) play (EQ IN) on the amplifier. This is the correct connection because it prevents clipping and increased noise due to insufficient level, and also lowers the noise of the equipment up to that point at the same time as the signal when the volume is turned down.
If this connection is made between the preamplifier and the mains, even if the volume is set to zero in the preamplifier, if noise is coming out of the EQ, the power amplifier will amplify only the noise, so residual noise will be generated from the SP.
If you turn up the preamplifier and increase the volume, the EQ amp will be overloaded.
EQ amp will be overloaded and clipped.
