Circuit Design

The SA-17S1 is developed to be a dedicated music player for both Super Audio CD and conventional CD. Not combining the video facility, it is outperforming the well-praised SA-12S1 on sound quality. The SA-17S1 has the potential to set a new musical multichannel reference in the market like the highest rated Super Audio CD player ever, the Marantz SA-1, did in the stereo market.

Zero-impedance matching joint and muting relays

Super-ring transformer

The SA-17S1’s analogue audio circuitry is a full discrete design including newly developed Current Feedback HDAM modules that operates as a buffer amplifier and as a Low Pass Filter. These devices are doing exactly the same thing as IC OP-amps but outperform the regular IC OP-amps dramatically in terms of slew rate, resulting in a much more dynamic, accurate and detailed sound. There are no IC OP-amps used at all in the SA-17S1’s analogue signal path. All six

channels are completely identical in terms of components and circuit layout. This is extremely important to be able to enjoy a breathtaking sound stage on multichannel Super Audio CD material.

Current Feedback HDAM

CS4397

The D/A converters are of course also identical for all six channels. Like in the SA-12S1 we have incorporated the high grade Cirrus-Logic’s CS4397. These DACs are applied in a similar manner as we did in the SA-12S1; this means 3 DACs are used for 6 channel.

In the final stage of the audio circuitry, the near to Zero-Impedance Matching Joint ensures the exact same ground potential for all channels. This improves the drivability of the next stage in your audio chain. The muting circuitry does not comprise of transistors but is designed with relay based switching, which contribute also to lower output impedance.

The SA-17S1’s power supply block is separated into several sections, in order to prevent any possible interference of digital noise into the analogue audio signal. Well-known sources of digital noise are the µ-processor and the FL display. An separate EI transformer is used for these two parts. In addition a Super-Ring transformer is applied for the audio circuitry dealing with both analogue and digital stages. The windings inside the copper shielded transformer are split and separated for the digital circuitry and for the analogue audio circuitry. The latter receives its power through a dedicated rectifier circuit that is placed in separated area to prevent any interference. The SA-17S1 is equipped with a wide variety of high-grade customized components and envisions Marantz’ know-how of Hi-Fi audio equipments. The Super-Ring power transformer is just one example. Other examples are the stress-free electrolytic capacitor and the shot-key diode. These are used in the rectifier circuit. High-grade electrolytic and film capacitors are used in the audio circuitry. All the regulators are covered with a copper plated shield that prevent regulator to vibrate and to prevent radiation of electro-magnetic noise.

Customised Capacitors

For the headphone listeners we have paid extra attention the headphone circuitry to ensure that the pure emotion of SACD is passed on. A dedicated amplifier is developed with a high speed Current Feedback circuitry constructed of discrete components only including a high grade potentiometer for the volume control.control.

Unique Features

Phantom Centre Mode

Phantom centre PCB

It is not always possible to install Centre channel speaker. Therefore the SA-17S1 facilitates a unique Phantom Centre Mode. Unlike a digitally down-mixed phantom centre that is mostly facilitated by DSP surround machine, the SA-17’s analogue mixing circuitry of the phantom centre won’t introduce quantisation noise.

Start Sound Mode

You can select which of the Super Audio CD’s layers (multichannel or stereo) to be read first after inserting a disc.

Output Filter Switch

Set this switch to ‘CUSTOM’ if your entire system is compatible with Super Audio CD’s wide band capability. Otherwise set it to ‘STANDARD’ to prevent inter-modulated distortion.
