The P.A.W. Model TC-50 Center Track Time Code/FM Processor (CTTC) was developed for use with the OTARI MX5050 series tape machines. After an in-depth study of market requirements and equipment feasibility, JRF Magnetic Sciences has developed and now offers Retrofit Kits for a select group of widely-used tape machines.
RETROFIT KITS are currently available for:
RETROFIT KITS are currently available for:
- Otari MX5050
- Studer A80
- MCI/Sony JH1 10 A/B
- Ampex ATR 100
The CTTC process is based on the use of four heads positioned within the tape path as diagrammed below:
Modifications to the TC-50 processor have been developed by JRF, and every unit is calibrated for the exact timing coincidence requirements for the specific model tape machine.
Included with each kit:
- P.A.W. Model TC-50 Time Code/FM Processor
- Upgrade of your existing head assembly to include:
- Refurbishing of audio record & playback heads
- Installation of new audio erase with CTTC (SEL-REP) head
- Installation of new CTTC erase & combo write/read head
- All required hardware
- Assembly and optical alignment
- Interconnect cable between head stack and TC-50 processor
- Time Code alignment tape
- Complete operation and maintenance manual
- Custom cable termination at head assembly (optional)
- New replacement audio record/repro heads (optional)
- Reproduce, SEL-REP (Sync), input, tape speeds, record-ready and enable are all manually engaged by front panel controls, requiring no interconnection to the tape machine.
- Three tape speeds (7.5, l5, and 3Oips) are time-compensated for coincident time-code versus audio track recording and reproduction.
- Internal adjustments, one each for record, reproduce, and SEL-REP set the coincident timing for the exact head distance in sub-frame accuracy.
- A front panel LED indicates timecode level for input and tape. These are automatically switched during record and reproduce functions.
- FM Pilot signal demodulated output. This signal is directed to the Pilot output XLR at line level for use with OTARI EC401 resolver (or equivalent), and is accomplished without changing the head or switch positions.
- The SYNCODE® feature demodulates the FM Pilot (and/or Mono Pilot with the addition of the optional MK-1 Kit) signal and at the same time records center-track timecode over the pilot track, thus eliminating generation loss during the transfer process.
