Yes, a Luxman R-1050 Bluetooth connection needs no soldering. Best path: a Bluetooth receiver with RCA output into the AUX input (150 mV into 30 kOhm, per the spec sheets). If AUX is taken, use a Tape loop. Rated 55 W/ch into 8 ohms below 0.05% distortion, with hifi-wiki quoting total harmonic distortion of 0.018%, the R-1050 opens the Luxman shelf in this archive.
Figures on this page were checked September 2026. Every table row carries its source; the two reference works agree on the shared power, impedance and weight figures, and differ on the THD quotation and the production end year.

Source codes: HW hifi-wiki.com · HE HiFi Engine transcription (Wayback snapshot). Data as of September 2026. The works agree on the shared figures; hifi-wiki's 0.018% THD is the tighter of the two distortion quotations, and the production end year differs (1980 vs 1981).
Where to connect
AUX input
RecommendedOne always-active line input at 150 mV into 30 kOhm, tighter than most receiver AUX inputs documented in this archive, though the late-B Marantz convention runs lower still at 20 kOhm. A line-level Bluetooth receiver with RCA output drives it without adapters.
Tape monitor loops
Good alternativeTape 1 and 2 at the same 150 mV / 30 kOhm spec, with record outputs for a deck. Feed a loop's play jacks, select the tape position to listen, and switch the monitor back off for the other sources.
Phono inputs
Not for line-levelThe two MM phono stages expect a cartridge's 2.5 mV and tolerate at most 150 mV. Line-level Bluetooth output would overload them, and the turntables would lose their inputs.
Set up in three steps
- Pick AUX
Keep the tape loops free for recorders; 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
- Luxman's shelf opens here (verified): this is the archive's first Luxman profile, and it arrives with a 0.018% distortion quotation per hifi-wiki's specification sheet, among the tightest documented here, alongside the transcription's matching 55 W figure.
- A 30 kOhm AUX, watch the source (verified): the AUX and tape inputs sit at 150 mV into 30 kOhm, tighter than most inputs documented here though the late-B Marantz 20 kOhm convention runs lower, so a source with high DC-offset behavior can shift the response; modern Bluetooth receivers are unaffected in practice.
- Two finishes, one record (verified): hifi-wiki documents the R-1050 and the R-1050 B in black with a rosewood cabinet option; the specification record covers the pair.
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
Plug a Bluetooth receiver with RCA output into the AUX input and select AUX. If AUX is occupied, use a Tape input through the tape monitor. No internal modification is needed.
Per the specification sheets: AUX and both Tape inputs take 150 mV into 30 kOhm, and the two MM phono inputs take 2.5 mV into 47 kOhm with a 150 mV maximum at 1 kHz. Signal-to-noise runs 66 dB on phono and 86 dB on tape and aux.
Continuous output is rated 55 W per channel into 8 ohms (90 W into 4 ohms) from 20 Hz to 20 kHz below 0.05% distortion, with hifi-wiki quoting total harmonic distortion of 0.018%, one of the tightest distortion quotations in this archive.
Yes: hifi-wiki documents the R-1050 B in black alongside the silver, both with the rosewood-cabinet option. The specification record covers the pair.
