Pioneer A-70DA Black

The Pioneer A-70DA amplifier is a unique product. The unique construction and equipment is targeted at the most demanding music enthusiasts. It uses symmetrical design and minimum signal path to ensure you have excellent sound performance with minimal noise. The shielded power transformer is isolation mounted, providing an excellent base for precision results evoking even the softest tones on reproduced tracks. The A-70DA amplifier uses the concept of digital power amplification in the final stages, working in energy-efficient Class D. Folded, shielded transformers provide the power. The first delivers a high current for output stages, along with the massive filter capacitors (2 x 10 000 uF). The second transformer supplies power directly to the preamplifier circuitry.

Inside, only the best!

The amply sized power transformer has separate windings for the power amplifier, preamplifier, and control circuitry to achieve optimum audio performance. If you like to listen to music at low volumes, you will also appreciate the Loudness function, reinforcing the bass and treble frequencies.There are also "Direct Energy" optimized, individual power circuits for the purest possible sound reproduction with minimal distortion. Class D amplification, which has a highly efficient and rapid response to signals, is used among the original parts. Class D's overall abilities far surpass analog amplifiers. A modern D/A converter with a Sabre Ultra ESS 32-bit circuit converts the signal. It also contains a programmable filter. A-70DA allows the USB-B input direct connection to a PC. The asynchronous transmission of signals from the computer to the amplifier is driven by a highly accurate clock.

Aluminium elegance

Construction is subject to maximum sound quality. The company uses only the highest quality components, gold-plated connectors and massive speaker terminals. An aluminium front panel offers unrivalled craftsmanship and stereo amplifier controls. At first glance you can see the aluminium knob for volume control, treble control, bass, balance and switch inputs. You can connect two pairs of speakers and switch between them in the A/B, and Bi-wiring. The amplifier can handle playback of most current digital formats stored on your PC or CD media. Finally, the Pioneer A-50DA equipped preamp for the turntable with MM pickup and the four inputs with gold plated connectors are brilliant and ready for the next fixed line signal. While listening, you will appreciate the comfort of the aluminium remote control.
