Taking conventional vinyl-discs in no way inferior to contemporary digital discs, the A & M have been introducing a series of analogue-related products such as the ATC-1, ATE-2, ATE-2001. Of late, many of the discerning audiophiles have been taking a new look at the existing vinyl discs, and recognizing anew the real value of analogue-recorded sounds.
Consistently sticking to analogue format employing vacuum tubes as amplifying components, now grandly introduced is the almighty phono equaliser amplifier ATE-2005.
1. Onboard head-amp for MC cartridge:
The low-noise, wide-band head-amp composed of FET provides necessary gain for MC type cartridges. Any impedance, whether low or high, shall be accommodated.
2. Tube for amplifying component:
The equalizer employing NF 2-stage,SRPP circuitry and low-impedance output stage insure high-precision RIAA compliance by means of stable NFB throughout entire frequency spectrum. Here used are the strictly selected & long-hour aged ECC83’s boasting of low noise & high stability
3. Removal of PCB:
To feed music signals unimpaired, we dare to employ painstaking manual wiring method, choosing the most suitable wires according to characteristics of each signal current.
4. Independent 4 sections:
To avoid mutual interferences for low-noise operation, the whole circuitry is divided into 4 different blocks, namely, MC amp, valves, EQ amp and power supply. For an EQ amp that deals with feeble signals from a cartridge, it’s indispensable to have low noise, low distortion and low loss characteristics. The rigid chassis structure suppresses vibrations independently in 4 functionally divided sections. The amp circuit specially disposed on the copper-plated portion to reinforce resistance to magnetism further helps shut off mutual interferences.
5?Multiple inputs, 1 MC & 2 MM:
The MC input coupled to the built-in head amp is for connection with the MC cartridge, while the other two MM inputs make it possible to utilise external connection of the MC step-up transformer or separate head amp.
6. Demagnetiser circuit:
The “degauss” function removes accumulated magnetism in cartridge core during playback of record disc.
