The Integrated Amplifier which considered the
balance of a performance, musicality, a style, user-friendliness, etc., and
repeated the enhancement based on SQ606, SQ505, etc.
complimentary SEPP OTL scheme is adopted as a power amplifier part.
has the composition of having excluded the protection network by using original
After a preamplifier part receives a two-step
hardwired-connection NF type equalizer circuitry in the emitter-follower stage and changes an impedance, it is amplified to suitable level with middle NF
amplifier, and has the composition of carrying out tone control by the LUX
scheme NF type tone control.
The transistor for low noises selected
carefully is adopted as this fraction.
Two speaker terminations are
The tone control has adopted the right-and-left standalone
version. Moreover, 18dB gain can be dropped on an Attenuator switchpoint.
Since there is a tapes monitor switchpoint, a simultaneous play monitor
can carry out on the tape recorder of three heads etc.
A whole surface
panel and thumbs carry out the hairline manipulation of the aluminum material, and alumite dyeing of the white gold has been carried out.
wood case serves as rosewood finish.
