ENGLISH OPERATION r Filter operations The filter settings can be made while the track is stopped. The filters shown in the table below are available for providing distinctive filtering according to the operation and Audio CD or Super Audio CD. Each time the FILTER button is pressed, the filter types cycle from FIL1 → FIL2 → FIL3 → FIL1. The filter setting has a memory retention function so that the setting remains stored and unchanged even when the disc is changed or the power is turned off. Filter Selection Table This unit is equipped with the "PEC 777f2" filter, developed with an improved algorithm from the digital filter for CD playback "SA11S1" (Phase Error Compensation 777 filter) that uses Marantz original DSP. When playing a super audio CD, the D/A converter internal filter is used. The filter has 3 types of built-in characteristics for both Audio CDs and Super Audio CDs, and the characteristics for each are shown in the table below. Change these settings according to your own personal preference. Filter type Audio CD Super Audio CD FILTER 1 FILTER 2 FILTER 3 This filter impulse response has a symmetrical and very short pre-echo and post echo characteristics. The phase response is absolutely linear. It reproduce all information of the recording in detail. The sound image is very profound, clear and very nice to listen to. Filter 1 does not touch the digital data stream coming from the Super Audio CD. It is the direct mode. The original source data is reproduced without any alteration. The maximum available bandwidth will be used. In combination with Marantz amplifiers this filter will provide the most accurate reproduction. This filter impulse response is asymmetrical and has a post echo which is slightly longer than the pre-echo. The characteristic is close to the sound of analog - it is well balanced between detailed and harmonic sound. Filter 2 dampens frequencies in the digital data stream from the Super Audio CD which are over the 100kHz to lower the bandwidth.In addition, operations within the D/A convertor are asymmetrical with priority given to resolution. This filter impulse response is symmetrical and has a very short pre-echo and post-echo. It provides high sound definition with the most detail along with a comfortable playback balance. Filter 3 dampens frequencies in the digital data stream from the Super Audio CD which are over the 100kHz to reduce the bandwidth. Operations with the D/A convertor are fully symmetrical. Note: Select the right filter by auditioning. The correct one will depend on your system and your personal preference. 21
