1/4" Instrument & Patch

• Guitar, bass and keyboard to amp or interface
• Patchbay to outboard gear
• Balanced line runs between rack units
• Insert sends and returns on a console channel

• TS: tip = signal, sleeve = shield and return
• TRS balanced: tip = hot, ring = cold, sleeve = shield
• TRS stereo: tip = left, ring = right, sleeve = common
• Shield bonded at both ends on instrument runs; telescoped where hum demands it

Long unbalanced instrument runs lose high frequency to cable capacitance. Over 20 feet we recommend a balanced TRS run or an active DI rather than a longer TS cable.

• 20 AWG stranded copper conductor, spiral or braided shield
• Nickel or gold-plated brass connector with metal chuck strain relief
• 60/40 or lead-free rosin-core solder
• Dual-wall adhesive heat-shrink for labels

• Tip and sleeve continuity end to end
• Tip-to-sleeve isolation with the plug open
• Capacitance sanity check on runs over 20 feet
• 10 lb pull test at the chuck

• — Materials are the bulk cable, connector pair, solder, boot and label for one finished unit at current supplier pricing.
• — Labor is measured build time at the bench, including test and labeling — not a billed rate.
• — Totals are internal cost-to-build planning ranges, not price lists, quotes, or guarantees. Supplier pricing moves.

Every finished unit in this line is numbered MET-YYYY-CBL-Q-NNNN and filed with the following fields before it leaves the shop.

1. 01 Cut to Spec

   Bulk cable is pulled from the spool and cut to the ordered length with a 2" service allowance at each end.

2. 02 Strip & Dress

   Jacket, shield and conductor insulation are stripped to the connector's spec, shield combed and twisted into a drain.

3. 03 Tin & Terminate

   Conductors are tinned and soldered to the correct pin, or crimped where the connector is designed for crimp.

4. 04 Strain Relief & Assembly

   The chuck or boot is seated on the jacket, the shell is closed, and the assembly is torqued by hand — never pulled tight by the wire.

5. 05 Electrical Test

   Continuity on every conductor, shield-to-conductor isolation, polarity check, and a pull test at the boot.

6. 06 Label & Accession

   Heat-shrink labels are applied at both ends with the length, family and accession number, then the record is filed.

7. 07 Coil, Bag & Shelve

   Over-under coiled, tied, bagged, and shelved by family and length in the cable locker.

• Soldering involves molten metal, hot tools, flux fumes and fine particulates. Ventilate the bench, wear eye protection, and let iron tips cool in a stand.
• The Cable Factory builds audio signal and microphone cables. It does not build, modify, or certify AC mains power cables, speaker cables carrying amplified mains-derived voltage above manufacturer rating, or anything requiring electrical code inspection.
• Cables built here are tested to the shop's own bench standard. That is a documented internal quality practice — not UL, ETL, CE, or any third-party certification, and not a warranty of fitness for a particular use.
• Connector and cable brands referenced in a build sheet are described for identification only. Naming a manufacturer's part is not an endorsement, partnership, or claim of affiliation.
• Costs shown are internal planning ranges for building a unit, not published prices, quotes, or projections of revenue or margin.

The Cable Factory is an internal fabrication and documentation practice at Node Zero. Build sheets, test standards, and cost ranges describe how the shop works; they are not certifications, warranties, safety approvals, legal advice, or price commitments. Anyone building cables should follow the manufacturer's specifications for their own parts and applicable local electrical rules.
