Yes, a Sansui G-9000DB Bluetooth connection needs no soldering. The AUX input is the standard home for a Bluetooth receiver with RCA output, with tape loops as the alternative documented across the Sansui shelf. Rated 160 W/ch into 8 ohms with a massive toroidal transformer, dual power supplies and built-in Dolby NR, it is the pinnacle of the G series, tied with the SX-1250 as the strongest receiver documented in this archive.
Figures on this page were checked September 2026. Every table row carries its source; the page states plainly which specification rows rest on collector and period sources.
Spec snapshot
| Item | Value | Notes | Source |
|---|---|---|---|
| Production run | 1978–1979 | Retail around $1,000 or more at the time | period/collector sources |
| Power output | 160 W/ch @ 8 Ω | The commonly cited figure for the pair; FR 5 Hz-50 kHz; THD 0.03%; S/N 78 dB | period/collector sources |
| Build signature | Toroidal + dual supplies | A massive toroidal transformer with dual power supplies | period/collector sources |
| The DB feature | Built-in Dolby NR | A Dolby noise-reduction section, mainly for FM broadcasts, built in on the DB variant | period/collector sources |
| Input table | Not documented | No checked source carries a G-9000DB input-sensitivity table; connection rows stay qualitative | gap, disclosed |
Data as of September 2026. This profile rests on period and collector sources; both standard reference sites carry no G-9000DB data, and the absences are part of the record.
Where to connect
AUX input
RecommendedThe always-active high-level spare, the standard home for an external source on receivers of this class. A line-level Bluetooth receiver with RCA output connects here; this page keeps the guidance qualitative because the G-9000DB's input-sensitivity table is not part of the documented record yet.
Tape monitor loops
Good alternativeThe tape loop through the monitor switch serves the same role documented across every receiver in this archive: feed the play jacks, select tape to listen, and switch the monitor back off for the other sources.
Phono input
Not for line-levelThe phono stage expects a cartridge. A line-level Bluetooth receiver would overload it, and the turntable would lose its input.
Set up in three steps
- Pick AUX
Keep the tape loops free for a recorder; AUX is the natural Bluetooth home.
- Connect and power
Bluetooth receiver RCA out to AUX, USB power attached, pair once with your phone.
- Level check
Volume low, select AUX, then raise. Fixed/line output on the adapter if it offers the option.
Quirks and notes
- The DB is the point (verified): built-in Dolby noise reduction is what separates the G-9000DB from the non-DB G-9000, the same naming logic the 9090 and 9090DB pair follows two shelves up. On the 9090, Dolby arrives through an external adapter; on the DB models, it ships inside.
- Toroidal muscle at the top of the line (verified): period and collector sources describe a massive toroidal transformer with dual power supplies, and the 160 W/ch figure is the highest documented on this site, tied with the SX-1250 and ahead of the Sansui 9090's 110 W and the Kenwood KR-9400's 120 W.
- A flagship with a thin paper trail (verified): for once, the reference sites have nothing, and this page says so in every relevant row. The 160 W figure travels with its collector-source attribution, and the input table waits for a factory document the same way the 630's and 730's do.
What you need
- Bluetooth receiver with RCA output, LDAC or aptX HD preferred
- 0.5–1 m RCA cable
- USB power for the receiver
FAQ
Use the AUX input for a Bluetooth receiver with RCA output and select AUX; if AUX is occupied, a tape loop through the monitor switch is the documented alternative across the Sansui shelf. No internal modification is needed.
The DB marks the built-in Dolby noise-reduction section, mainly for FM broadcasts, the feature that separates the DB from the non-DB G-9000. The same naming logic runs through this archive: the 9090 takes Dolby through an external adapter and the 9090DB builds it in.
Period and collector sources consistently quote 160 W per channel into 8 ohms, delivered through a massive toroidal transformer with dual power supplies. It ties with the SX-1250 as the highest power figure documented on this site, ahead of the KR-9400's 120 W and the 9090's 110 W.
Because no input-sensitivity table for the G-9000DB has surfaced in the sources checked: hifi-wiki's G-9000DB page is empty, the classicreceivers DB page is a 404, and no G-9000DB factory document has surfaced. The non-DB G-9000's 160 W figure is commonly cross-cited for the pair and is noted as such.
