Build Your Loudspeaker - The Pioneer Kit (1975)

 

Build Your Loudspeaker - The Pioneer Kit (1975)

Brand: Pioneer
Model: AS-302 + AE-300 + EB-302
Year: 1975

This top quality kit consisted of the AS-302 speaker/cross-over/terminal/acessoires set that had to be mounted into the AE-300 flat-pack enclosure you had to build (front grill included) using the EB-302 baffle (exclusive to AS-302). This will result in a 3-way closed loudspeaker system with 30cm carbon fibre woofer, 4,8cm dome midrange and 2,5cm titanium dome tweeter. The enclosure has an internal volume of 50 liters and the panels are 21mm thick. The particle board panels have a wood grain finish.

PIONEER SOIGNÉ (1989)

 

PIONEER SOIGNÉ hifi system

The SOIGNÉ (elegantly done) was a contemporary component system introduced by Pioneer in 1989. It was described as a "Simple & Quality Urban Component". The CCS-7100 system presented here features a 75W/ch (EIAJ 6ohm) amplifier with a THD of 0,005% partnered by a CD-Tuner combo unit, a twin cassette deck (both deck auto reverse) with Dolby B-C and HX-Pro and a frequency response of 20-19,000Hz with Metal tape. Both cassettes are 2+1 motor with a wow&flutter figure of 0,055% (WRMS). The loudspeaker of this system is a phase reversed, magnetically shielded bookshelf model with two 14cm woofer (one at the front, one at the back) and a 2,5cm Titanium dome tweeter. Power rating is 90W with a frequency response of 40Hz-40kHz and an impedance of 6ohm. Typical dimension of a unit is 360x90x355mm (WxHxD). A low profile equipment rack and speaker stands were available separately.

DENON PMA-780D (1987) - Stereo Integrated Amplifier

 DENON PMA-780D (1987) - Stereo Integrated Amplifier


Stereo Integrated Amplifier

Brand: DENON
Model: PMA-780D
Year: 1987

The PMA-780D was a completely new type of integrated amplifier equipped with a digital multi-interface circuit and a D/A converter circuit that directly receives music information sent from CDs, DAT, DBS (PCM satellite broadcasting), etc. as digital signal. This unit is equipped with 3 digital input circuits and automatically selects the sampling frequency of CD, DAT, and DBS. Furthermore, it is equipped with a double super linear converter circuit that uses a high-precision digital filter and independent D/A converters for left and right channels, converting it into a pure audio signal and directly driving the power amplifier. The amplifier section is equipped with a super non-feedback power amplifier that boasts high speed, and a pure dynamic power circuit that uses a powerful power transformer, dramatically improving instantaneous power supply capability and delivering unwavering high dynamic power of 350W + 350W/2Ω. Furthermore, it is equipped with a wealth of functions such as a phono equalizer amplifier, a processor loop, and three recording/playback terminals.

Continuous power: 2X110W (8ohm, 20Hz to 20kHz, both channel driven)
Total Harmonic Distortion: <0.004%
Frequency Response: 5Hz-100KHz (IHF, both channel driven, THD 0.5%)
Digital Audio Interface for CD, DAT, DBS (PCM satellite)
Total harmonic distortion 0,0025%
Signal to noise: 105dB
Dynamic range 96dB
Dimensions (WxHxD): 434x172x396 mm
Weight: 15,6 kg
