reel to reel




The PIONEER RT-1050, besides qualifying as a fully-profesional studio deck with its half-track (2-track) stereo head design and choice of the extra-fast 38 cm/se. tape speed, it also provides the convenience, economy and versatility of the best home-type deck. As standard equipment, the RT-1050 provides the same half-track head arrangement used in all recording studio equipment for 1/4" tape. This arrangement will use the entire width of the tape to store the two stereo channels in one tape-running direction to result in increased accuracy and improved audio characteristics. 

For extra versatility the RT-1050 accepts an optional plug-in head assembly (PP-204T) for 4-track recording and playback. Also standard on the PIONEER RT-1050 is it's two-speed drive system with 19 cm/sec. and professional 38 cm/sec. speeds selectable at the push of a button. The higher, 38 cm/sec. speed is a world-wide standard for half-track studio machines and provides the most ideal audio results possible with 1/4" tape. The deck's 3-motor tape transport system is beefed up to handle all reel sizes up to studio-use 27 cm type with ease. A 5mm - thick chassis and solid, die-cast framework provide additional strength. So that you can use any type of tape with minimum distortion and maximum performance, the RT-1050 is equipped with a three-step BIAS selector (STD, LH-1, LH-2) and a four-step EQ selector (NAB STD/LH and IEC STD/LH). 

Dual-scale level meters, a recording peak indicator, lockable, feather-touch electronic controls and many other Pioneer luxury touches add control convenience and versatility to this unusual stereo tape deck.

power amplifier

The Victor (JVC) M-L10 power amplifier was introduced in 1981 and was based on the earlier Laboratory Series M-7050 from 1979.  The power amplifier is based on the high efficiency class A operation method called "Super A" with zero switching noise. The output stage transistors operates at a constant voltage, only the current is changed, and the whole stage adopts a cascade cicrcuit construction. A distinctive (21 step laquering) mirror finish real wood cabinet is used for both the pre-amplifier and power amplifier. This beautiful Laboratory Series amplifier combo was sold under the Victor brand name in Japan while worldwide it was sold as JVC. Technical data: 160 W/ch (RMS, 8 Ohm, 20Hz-20Khz, 0.002%THD), Dimensions: 46*20.35*41.75, Weight: 28 kg
