  • Notes

  • A Stereo Phono Equalizer in Rotel's 'Michi' High-End Series of Hi-Fi separates. Fully symetrical circuit topology. Three-layered approach to equalization, the first process is a gain stage from the input cartridge signal using a fully complementary push-pull circuit, the second stage consists of equalization for high frequency content which is carried out by a passive pole low-pass filter, the third process is a further gain stage which uses active equalization for the low frequency requirement. Final output is via a single-ended fully complementary push-pull circuit with class A operation. The RHQ-10 will work with Moving Coil and Moving Magnet cartridges. Two pairs of output sockets, 'Fixed 1' and 'Variable/Fixed 2', for connection to the Rotel RHC-10 Stereo Passive Controller or the Rotel RHA-10 Stereo Active Controller, or other suitable preamplifiers. Power On/Off switch with power on indicator and an Attenuator rotary control, the front section controls the right channel output volume to the preamplifier, the rear section the left channel output volume.
