Yes, a Sansui 2000X Bluetooth connection needs no soldering. Best path: a Bluetooth receiver with RCA output into the AUX input (150 mV line level per the manual transcription). If AUX is taken, use a Tape loop. Power is quoted at 39 W/ch into 8 ohms by the manual transcription and about 35 W by period coverage; both figures are shown, and either way this entry-level Sansui asks for sensitive speakers.
Figures on this page were checked September 2026. Every table row carries its source; the two sources' power figures differ and both are printed with attribution.
The 2000X in numbers
| Item | Value | Notes | Source |
|---|---|---|---|
| Production run | 1971–1975 | Dated 1971 per the transcription and radiomuseum; period coverage runs it to about 1975 | HE, CR, RM |
| Power output | 39 / about 35 W/ch @ 8 Ω | 39 W per the manual transcription; "about 35 watts" per period coverage; both quoted | HE, CR |
| Phono input | 2.5 mV (MM) | S/N 70 dB (MM) against 80 dB (line) | HE |
| Line inputs | AUX · Tape | AUX/line 150 mV; DIN record output 30 mV; speakers 4-16 ohms | HE |
| Weight | 13.1 kg | Dimensions 462 × 147 × 335 mm; semiconductors counted in the transcription | HE |

Hookup points on the 2000X
AUX input
RecommendedAUX/line takes 150 mV per the manual transcription, the figure the bigger Sansuis of the era document on their high-level inputs. A line-level Bluetooth receiver with RCA output is a straightforward match.
Tape monitor loop
Good alternativeThe Tape Play input at 150 mV is the loop, and a 30 mV DIN record output serves European decks. Feed Bluetooth through it: plug into the play jacks, choose the tape position on the monitor, and take the monitor back off afterwards.
Phono input
Not for line-levelThe MM phono stage is built for a cartridge's 2.5 mV. Line-level Bluetooth would overload it, and the turntable would lose its input.
Getting the 2000X connected
- AUX is home base
The tape loop stays with a recorder; the Bluetooth receiver lands on AUX.
- Hook up the hardware
The Bluetooth receiver's RCA output into AUX, USB power attached, and pair with your phone once.
- Volume in small steps
Volume low, AUX chosen, then up. If the adapter has fixed/line output, that is the setting.
2000X quirks worth knowing
- Two wattage figures, attributed (verified): the manual transcription's 39 W and period coverage's "about 35 watts" both describe the 2000X. As with the SX-727's 40-versus-37 spread, this page prints both rather than picking a winner.
- The entry Sansui, honestly rated (verified): with 0.8% distortion at rated output and a 24 damping factor, the specification itself signals entry-level duty. The 9090 and 8080 profiles document where the range went from here.
- An anomalous block, disclosed (verified): the transcription page carries a first specification block (75 W, 0.3 mV, 0.55 kg) that does not describe this receiver; this profile documents the receiver-consistent block and records the anomaly rather than quoting either indiscriminately.
What you need for the 2000X
- Bluetooth receiver with RCA output, LDAC or aptX HD on top
- An RCA cable of 0.5–1 m
- A USB supply for the receiver's power
FAQ
Plug a Bluetooth receiver with RCA output into the AUX input and select AUX. If AUX is occupied, use a Tape Play input through the tape monitor. No internal modification is needed.
Per the manual transcription: AUX/line 150 mV and MM phono 2.5 mV, with a DIN record output at 30 mV, into speakers of 4 to 16 ohms. The high-level input spec is the same 150 mV the bigger Sansuis of the era document on their AUX inputs.
Both figures are on record: the manual transcription says 39 W into 8 ohms and period coverage says about 35 W. This page shows both with attribution instead of picking one.
At 39 W or 35 W into 8 ohms with 0.8% distortion at rated output, it is an entry-level power figure, and this page says so plainly. With sensitive speakers it fills a room; with power-hungry ones, look up the bigger Sansuis documented on this site.
