Symetrix 402 Dual Output Delay — 4 units available (sold as lot or individually)

Four fully tested Symetrix 402 Dual Output Delay units, professionally verified using RiTA measurement software in loopback configuration.

SPECIFICATIONS:

• 1 input / 2 independent outputs

• Delay range: 1ms steps, up to 885ms (theoretical)

• 20-bit oversampling A/D and D/A converters

• Dynamic range: >104 dB

• 12-segment LED peak input display

• Rear panel lockout switch (tamper prevention)

• Bypass mode: hard-wired input to output

• Non-volatile memory for delay settings

• Power: 12.5W, 117V / 230V selectable

• Made in USA (Symetrix Inc., Lynnwood, WA)

TESTED & VERIFIED — SERIAL NUMBERS:

• SN 393AC542 — fully functional, both outputs verified

• SN 495AAN — fully functional, both outputs verified

• SN 193AA537 — fully functional, both outputs verified

• SN 293AAB505 — fully functional, both outputs verified

VERIFICATION RESULTS (RiTA loopback measurement):

• Reference signal: direct loopback to RiTA reference input

• Measured signal: Symetrix 402 output routed back to RiTA measurement input

• Processing latency: 1.49ms at 0ms setting — consistent with 20-bit oversampling converters

• Delay increment: 1ms/step, proportional and accurate throughout range

• Operational range verified: up to 682ms with full signal coherence

• Above 682ms: signal coherence breaks — consistent with RAM degradation due to age, no impact on professional time alignment applications (typical use: 0–300ms)

CONDITION: Good

All 4 units fully functional within verified operational range. Signs of professional use. Delay settings stored correctly in non-volatile memory.

PRICING:

• Full lot (4 units): 250€ (negotiable — offers welcome)

• Individual units: 70€ each

Collection preferred — Barcelona area (Esplugues de Llobregat), Spain.

Shipping possible at buyer's expense — units are compact and easy to ship safely.
