Yes, a Yamaha CR-1020 Bluetooth connection needs no soldering. Best path: a Bluetooth receiver with RCA output into the AUX input (120 mV into 45 kOhm per the spec sheets). If AUX is taken, use one of the two Tape loops. Power is quoted at 75 W/ch into 8 ohms by hifi-wiki's service-sheet data and 70 W/ch by period coverage; both are shown, and either figure tops or matches this site's CR-1000 profile at 70 W/ch.
Figures on this page were checked September 2026. Every table row carries its source; where the two sources disagree on a number, both figures are shown with attribution.

Where the CR-1020 takes a source
AUX input
RecommendedAUX and the tape inputs share a 120 mV / 45 kOhm table, the exact figures the CR-820 profile carries. A line-level Bluetooth receiver with RCA output runs cleanly off AUX, and the level check is still worth its minute.
Tape monitor loops
Good alternativeThe two tape inputs repeat the 120 mV spec, and the rear panel adds a Dolby FM adapter loop plus a Pre-Out/Main-In coupler per period coverage. Connect to a loop's play jacks, dial the monitor to that tape position, and dial it back to off for the other sources.
Phono inputs
Not for line-levelTwo phono stages wait at 2 mV / 47 kOhm, three kOhm off the CR-820's manual figure. They are cartridge inputs; a line-level Bluetooth signal would overload them, and the turntables would lose their inputs.
From pairing to playing on the CR-1020
- Start at AUX
The tape loops belong to recorders first; AUX is the Bluetooth input.
- Join and power it
RCA output of the Bluetooth receiver goes to AUX, a USB line powers it, and your phone pairs once.
- Bring the sound up
Volume low, AUX chosen, then up it goes. Where the adapter provides fixed/line output, that is the mode to select.
CR-1020 quirks worth knowing
- Two wattage figures, both printed (verified): 75 W per hifi-wiki's service-sheet data and 70 W per period coverage describe the same amplifier from different measurement habits. The page shows both, attributed, instead of averaging history.
- The CR-820's AUX table, repeated (verified in part): the AUX and tape figures, 120 mV / 45 kOhm, match the CR-820 profile exactly; the phono impedance differs by 3 kOhm, 47 here against that set's 50. The level check guidance carries over unchanged.
- A coupler worth knowing (verified): period coverage lists a Pre-Out/Main-In coupler among the rear-panel features, the same jumper arrangement the Marantz profiles document, and it stays in place for a standard Bluetooth setup.
The parts list for the CR-1020
- Bluetooth receiver with RCA output; LDAC or aptX HD rank first
- RCA cable of 0.5–1 m
- USB power to keep the receiver running
FAQ
Plug a Bluetooth receiver with RCA output into the AUX input and select AUX. If AUX is taken, use a Tape input through the tape monitor. No internal modification is needed.
Per the specification sheets: AUX and both Tape inputs take 120 mV into 45 kOhm, matching the CR-820's table, and the two phono inputs take 2 mV into 47 kOhm, where the CR-820's manual-anchored table reads 50 kOhm. Pre-Out and Main-In couplers are on the rear panel per period coverage.
Both figures are on record: hifi-wiki's service-sheet data says 75 W into 8 ohms (90 W into 4 ohms), and period coverage says a hefty 70 W. This page shows both rather than picking, the same treatment the SX-727's 40-versus-37 figures get.
Period coverage calls it the younger brother of the CR-3020 and CR-2020, and against this site's profiles it tops or matches the CR-1000's 70 W/ch depending on which power figure you quote, and sits well above the CR-820's 55 W/ch.
