2. Start-Up 1. Power On/Off Press the ‘POWER’ switch (R5) at the rear of the CD-77 to switch mains power ON to the CD-77. Once powered OFF: always wait 20 seconds before switching on again To switch the mains power OFF, press again and release. Always WAIT at least 20 seconds before switching on again. This is to enable the OptiMains® circuit to shutdown properly. The display will light up to indicate the unit is switched on and ready for use.
2. Standby After start-up, pressing the STANDBY button (F1) on either the front fascia or the RC-77 (RC5), the CD-77 will switch to STANDBY mode. Standby will maintain power to the non-valve circuitry Standby By pressing this button again, the CD-77 will commence warm-up to prepare for operation. Under STANDBY mode, power to CD-77’s digital circuit is kept active in order to provide the optimum performance for the next listening session.
Upon closing the door, play will automatically commence from Track 1. This Autoplay feature can be enabled/ disabled by simultaneously pressing the STOP button (F5) on the front fascia of the CD-77 and pressing the PLAY/PAUSE button (RC8) on the RC-77 remote control. Always use the CD puck NOTE: The CD-77 has been designed to play all types of compact discs including the CD layer of hybrid SACD’s. However, as such discs are thicker, please ensure the CD puck is positively engaged with the spindle.
6. Stop At any time, pressing the STOP button (F3) once on either the front fascia or the RC-77 (RC7) will halt playback. 7. FWD/Next At any time, pressing FWD (F4) once on either the front fascia or the RC-77, the next track will be selected. By holding down FWD (F4) or (RC9), playback will fast forward until the button is released. 8. REV/Reverse At any time, pressing REV (F2) once on either the front fascia or the RC-77 (RC6), the previous track will be selected.
10. Repeat (RC-77 only) If the REPEAT button (RC2) is pressed once: Repeat One will be displayed and the current track will be repeated. If the REPEAT button (RC2) is pressed AGAIN: Repeat All will be displayed: once the last track of the compact disc has been played, instead of stopping, the CD-77 will revert to Track 1. 11. A-B (RC-77 only) The A-B button (RC3) is for the manual selection of a chosen piece of music within a track for repetition.
Repeat A-B will be displayed with the letter ‘B’ flashing. This means that it has commenced the selection of that passage of music. By pressing the A-B button (RC3) again: Repeat A-B will be displayed with the letter ‘B’ no longer flashing. This is to confirm the particular passage of music has been identified and repeat will commence. To cancel this program, press the A-B button (RC3) again. 12.
v. Go to ‘Control Panel’ > ‘System’ > ‘Hardware’ > ‘Device Manager’. In ‘Device Manager’ wait until the personal computer in ‘Hardware’ has recognised the CD-77 as a ‘USB Audio Device’. This is found under the ‘Sound, video and game controllers’ category. vi. Go to ‘Control Panel’ > ‘Sounds and Audio Devices’ > ‘Audio’. Make sure ‘USB Audio Device’ is selected as the default device under the ‘Sound playback’ box. vii.
15. Time (RC-77 only) Normally the display will show the time elapsed since the beginning of the current track but pressing the TIME button (RC12) on the RC-77, the display will show and cycle through: Elapsed Track Time > Track Remaining > Total Remaining 16. Scan (RC-77 only) Press the SCAN button (RC13) once: Intro Scan 10s will be displayed and the first 10 seconds of every track will be played before moving onto the next track until all tracks have been played.
By pressing the SCAN button again: Intro Scan 30s will be displayed and the first 30 seconds of every track will be played until all tracks have been played. 17. Program (RC-77 only) Press the PROGRAM button (RC13) and: Program No: 01 will be displayed. Thereafter select the track via the numeric keypad (RC1). Program No: 02 will then be displayed and the same routine is repeated. To commence playback, press PLAY/PAUSE (RC8).
18. Shuffle (RC-77 only) Press the SHUFFLE button (RC15) and the playback of music tracks will be randomly selected.
Section 3 - Advanced Features The following section describes and where relevant, provides instructions to access the CD-77’s advanced features. 3a. OptiSample® The CD-77 Compact Disk Processor offers 6 user-selectable methods of Sampling that can be ‘cycled through’ during playback by pressing the OptiSample® button (RC10) on the RC-77. The sampling options are: Digital Master II is the benchmark for playback 1.
a large degree of digital manipulation. The original data from the CD is in effect discarded and re-placed with a re-calculated version. This new version of the music is mainly linearly scaled up using a whole number as scaling factor and resolution/edge enhanced. The sonic result of Oversampling 4x is similar to that of Oversampling 2x; except more accentuated. OptiSample modes 4-6 offer more typical versions of digital playback 5.
3b. DAC Input An S/PDIF link was not offered as this method results in excessive sonic degradation It is possible to allow playback of a large library of music to an exceptionally high standard through the CD-77’s DAC option (See Section 2 item 12 for connection details). Under the DAC mode, the DAC section of the compact disk processor will disengage from the transport section. Instead, the digital signal from the USB input (R3) located at the rear of the CD-77 will be used as the music signal source.
3e. OptiMains® Protection for Excessive Under/Over-Voltages The CD-77 is fitted with the OptiMains® system to condition and adjust the incoming mains supply for the best operation under all normal mains conditions (including situations that will cause audible problems without OptiMains®). In the event there are excessive mains fluctuations...
Section 4 - Technical Features The following section provides a brief explanation of the most salient technical features of the CD-77. The original Philips TDA1541A digital-to-analogue converter in AMR’s testing and auditioning remains to-date, the most musically satisfying chipset for digital-to-analogue conversion. OptiSignal® conditioning circuit has optimised every single operating parameter of the Philips TDA1541A including off as well as onboard circuits.
Appendix - Troubleshooting & Maintanence Figure A.
Maintenance i. About the Optical Pickup The CD-77 uses a solid-state semi-conductor diode laser, mounted on a tracking servo-mechanism to play the disc. The laser illuminates the track of microscopic pits representing the digital data bits, while photo-diodes detect the reflected illumination from the disc and convert it into an electronic signal which is then decoded to recover the musical waveform in each stereo channel.
iii. CD-R & CD-RW Audio Discs The CD-77 can play CD-R & CD-RW audio discs that have been recorded on a computer or CD-recorder. The quality of CD-R & CD-RW audio discs varies widely which may affect playability. iv. Handling Compact Disks Always handle Compact Discs with care. The playback of a disc will not be impaired by small dust particles, a few light fingerprints, or slight scratches. But large scratches, or a thick layer of oily fingerprints, can prevent the CD-77 from tracking the disc properly.
