Revision as of 01:19, 27 June 2015
The webmaster has the following equipment at his disposal to digitize or transfer several different formats.
Magnetic media
Audio cassette tapes
Nakamichi Cassette Deck 1
- Three head, asymmetrical dual capstan transport with pressure pad lifter
- Manual playback azimuth adjustment, allowing best frequency response of a tape that was recorded on any other device
- Upgraded with:
- Pacific Stereo Universal Capstan Motor
- Two underspec'd capacitors in the playback amplifier circuit replaced with high-quality, audio-grade, properly spec'd caps to prevent potential channel imbalance or failure and the rest of the playback amp board's capacitors has been replaced as well; see this Tapeheads.net forum thread for more details
- Serviced:
- Tape speed, default head azimuth, head height, playback level and frequency response, etc calibrated against A.N.T. Audio's stellar alignment tapes
- Performance checked against calibration tapes about every six months
- Factory belt kit from Marrs Communications ensures wow & flutter figures meet or exceed factory specifications
- Tape path thoroughly cleaned and demagnetized regularly, approximately 10 hours of use between cleanings and 30 hours between demagnetization using a wand-type demagnetizer
- Tape transport cleaned and relubricated as of June 2015 (includes capstan flywheels and thrust bearings, reel hubs, and reel motor shaft; new replacement capstan motor mentioned earlier does not need relubrication for several years from installation date)
- Tape speed, default head azimuth, head height, playback level and frequency response, etc calibrated against A.N.T. Audio's stellar alignment tapes
- Output stage:
- Mediabridge 6 foot RCA to 3.5mm cable -> ASUS Xonar DX sound card with 112dB input signal-to-noise ratio (32-bit depth and 96khz sample rate) -> Adobe Audition CC 2014.2 (recording at 32/96)
- Each tape is fully wound (fast forwarded) and then rewound to ensure tape spools are packed with the least amount of potential stiction that may result from a long time spent in storage
- Azimuth is optimized per tape, and if required, per each individual tape's side
Digital Audio Tape (DAT)
Sony SDT-9000 SCSI DAT drive
- Flashed with firmware that is able to read audio DATs
- Most direct option to rip audio DATs to WAV format in their native sample rate (i.e. 16-bit 32khz / 44.1khz / 48khz)
- Allows error correction which no standalone DAT deck / recorder can perform
- Regularly cleaned according to manufacturer recommendations using "new old stock" Seagate DAT head cleaning tapes
- DATs ripped using dat2wav software
VHS / S-VHS
NTSC & PAL
- Philips VR1000 (JVC rebadge) with built-in line time base corrector or JVC HR-S7600U with built-in line time base corrector
- DataVideo TBC-1000 full-frame time base corrector
- ATI All-In-Wonder 9600XT AGP video card for lossless Huffyuv AVI captures captured on a dedicated Windows XP Service Pack 2 computer
- Other general computer specifications: HP Compaq d530 CMT computer with Pentium 4 Extreme Edition 3.2ghz with HyperThreading, 1.5GB DDR-400 RAM, 80GB Western Digital Velociraptor + 500GB Western Digital Blue hard drives, Creative Sound Blaster X-Fi XtremeMusic, Microsoft Windows XP Service Pack 2
- Audio captured using high quality Monster RCA cables passed through capture card to Creative Sound Blaster X-Fi XtremeMusic sound card
Optical Media
Compact Discs / CD-R
- The latest version of Exact Audio Copy configured to optimal settings for a perfect rip
- Optical drive used does not affect the result of the rip
DVD
BD
- Not applicable at this time due to no Blu-Ray bootlegs existing that need to be ripped; as far as I know, only one or two BD recordings have been torrented on DIME.
MiniDisc
Sony MDS-S707 MiniDisc deck
- Optical output is used for digitally bit-perfect captures
- Many thanks to Ryan Jonik for his generous contribution
Vinyl / LP
Audio-Technica AT-LP120-USB Direct-Drive Professional Turntable + Shure M97xE Cartridge
- Output stage:
- RCA to 3.5mm cable -> Creative Sound Blaster X-Fi XtremeMusic sound card (32-bit depth and 96khz sample rate) -> Adobe Audition CC 2014.2 (recording at 32/96)
