|
Type:
|
Medium weight, medium compliance, low-impedance moving coil cartridge
|
Stylus:
|
Lyra-designed long-footprint variable-radius line-contact nude diamond (3um x 70um), slot-mounted
|
Cantilever system:
|
Diamond-coated solid boron rod with short one-point wire suspension, directly mounted into cartridge body via high-pressure knife-edge system
|
Coils:
|
2-layer deep, 6N high-purity copper, cross-shaped chemically-purified high-purity iron former, 4.2ohm self-impedance, 11uH inductance
|
Output voltage:
|
0.56mV@5cm/sec., zero to peak, 45 degrees (CBS test record, other test records may alter results)
|
Frequency range:
|
10Hz ~ 50kHz
|
Channel separation:
|
35dB or better at 1kHz
|
Compliance:
|
Approx. 12 x 10-6cm/dyne at 100Hz
|
Vertical tracking angle:
|
20 degrees
|
Cartridge body:
|
One-piece machining from solid titanium billet, with reduced-surface higher-pressure headshell contact area, predominately non-parallel and asymmetrical shaping, phase-interference resonance-controlling mechanism, and body threaded directly for mounting screws
|
Cartridge mounting screws:
|
2.6mm 0.45 pitch JIS standard
|
Distance from mounting holes to stylus tip:
|
9.5mm
|
Cartridge weight (without stylus cover):
|
11.6g
|
Recommended tracking force:
|
1.65 ~ 1.75g (1.72g recommended)
|
Recommended load directly into MC phono input:
|
104ohm ~ 887ohm (determine by listening, or follow detailed guidelines in user manual)
|
Recommended load via step-up transformer:
|
5 ~ 15ohm (step-up transformer's output must be connected to 10kohm ~ 47kohm MM-level RIAA input, preferably via short, low-capacitance cable)
|
Recommended tonearms:
|
High-quality pivoted or linear (tangential) tonearms with rigid bearing(s), adjustable anti-skating force, preferably VTA adjustment
