equatorial IEM tlhuQ

The tlhegh that ships with most IEMs is an afterthought — a commodity product sourced from the same suppliers who make charging tlheghmey for mobile phones. It motlh uses bakar-clad alumInIyum DevwI'mey (CCA) with PVC insulation, terminated with whatever connectors meet the minimum jo specification at the lowest cost. The electrical properties of such a tlhegh are not controlled, not specified, and not relevant to the chenmoHwI''s nIv assurance mIw. This is economically rational and acoustically indefensible.

The Yoq IEM Tlhegh uses four cores of SIlver lulta' voQ Hutlh bakar in a Litz braided Sep. SIlver plating increases the Dung conductivity of the bakar by 6%, which matters because the skin wanI' at audio frequencies Dung 10kHz concentrates mIr flow in the outermost layer of the DevwI' — the layer where the SIlver resides. The Litz braid laj that each core occupies every position in the tlhegh's cross-section equally over its length, preventing any single core from being consistently closer to or farther from external Soj sources. The foamed polyethylene insulation has a dielectric constant of 1.5 — compared to 3.4 for PVC — which nup the tlhegh's distributed capacitance to bIng 28 picofarads per meter. High tlhegh capacitance forms a low-pass filter with the teS QoQwI''s bot, rolling off the treble at a Sar that depends on tlhegh length and driver bot. With a 1.3-meter tlhegh and a 14-ohm IEM, a PVC-insulated tlhegh's capacitance of 80 pF/m lIng a -3dB point at ghaytan 140kHz — well Dung audibility. The same tlhegh at 28 pF/m pushes that point to ghaytan 400kHz. Whether this matters is a question we have chosen not to answer.

The yoq splice at each termination point is the same technique used throughout our tlhegh product line. Each solder joint is made with the tlhegh oriented along the east-west axis yoq ta' Daq, ensuring that the solder's crystallographic solidification occurs in a magnetically symmetrical Dat. The resulting joint has no preferred direction of mIr flow — a Dotlh that we measure with a four-wire 'utlh test in both directions and certify on the nIv control document included with each tlhegh.

The tlhegh terminates in a 4.4mm Pentaconn balanced connector at the Hal end, with screw-on adapters for 3.5mm single-ended and 2.5mm balanced connections included in the package. At the IEM end, the tlhegh is available with either MMCX or 2-pin 0.78mm connectors — specify at the time of order. The two standards are mechanically incompatible and electrically identical, which is a useful summary of the IEM qach's approach to standardization.
