Specifications for LYRA ETNA

Designer: Jonathan Carr

Builder: Yoshinori Mishima

Type: Medium weight, medium compliance, low-impedance moving coil cartridge

Stylus: Lyra-designed long-footprint variable-radius line-contact nude diamond (3um?70um profile, block dimensions 0.08 x 0.12 x 0.5mm), 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, 6 N high-purity copper, chemically-purified high purity iron X-shaped former, 4.2 ohm self impedance, 11uH inductance

Output voltage: 0.56 mV@5 cm/sec., zero to peak, 45 degrees (CBS test record, other test records may alter results)

Frequency range: 10 Hz-50 kHz

Channel separation: 35 dB or better at 1 kHz

Compliance: Approx. 12 X10 cm/dyne at 100 Hz

Vertical tracking angle: 20 degrees

Cartridge body: Multi-material (titanium, duralumin, bronze, stainless steel) self-clamping construction with reduced-surface higher-pressure headshell contact area, predominately non-parallel shaping, phase-interference resonance-controlling mechanisms, body threaded for mounting screws

Cartridge mounting screws: 2.6 mm 0.45 pitch JIS standard Cartridge weight (without stylus cover): 9.2g

Distance from mounting holes to stylus tip: 9.52mm

Recommended tracking force: 1.68-1.78g (1.72 g recommended)

Recommended load directly into MC phono input: 104 ohm-887ohm (determine by listening, or follow detailed guidelines in owner's manual)

Recommended load via step-up transformer: 5-15 ohm (connect step-up transformer's output to 10kohm-47kohm MM-level RIAA input, preferably via short, low-capacitance cable)

Recommended tonearm: High-quality pivoted or linear (tangential) tonearm with rigid bearing(s), adjustable anti-skating force, preferably VTA adjustment
