“Swap” can mean changing which speaker plays the left or right stereo channel, switching between stereo and same-audio playback, or selecting a speaker pair. The control’s effect depends on the model: identify your speakers or receiver before changing settings. On Yamaha’s NX-70A, for example, L/R SWAP changes the channel assignments of the two physical speakers; it does not exchange the cabinets.
What a speaker “swap” control can change
“Swappable speaker controls” is not a standardized industry term. A control described as a swap may affect channel assignment, playback mode, or which speaker outputs are active. Other speaker controls may only adjust sound or playback.

- Left/right assignment: Sends the left and right stereo channels to the opposite physical speakers. Yamaha documents this function on the NX-70A. Yamaha NX-70A instructions.
- Stereo or same-audio mode: Sony’s Speaker Add function can play the same sound on both speakers in double mode, or left and right channels in stereo mode. Some supported models can also change which unit carries each channel. Sony Speaker Add guidance.
- Speaker-pair selection: A receiver or selector may enable or disable groups, such as front speaker A, B, or A+B. That selects outputs; it does not necessarily reverse left and right. See the instructions for your receiver or selector, such as the OEM Systems SW-4SPKR manual.
- Volume, bass, source, or power: These are ordinary operating controls, not channel swapping. Klipsch documents these functions on its ProMedia 2.0 system. Klipsch ProMedia 2.0 controls.
How to swap left and right speakers on the Yamaha NX-70A
On this model, the factory assignment is primary speaker left and secondary speaker right. Pressing L/R SWAP on the primary speaker changes the assignment: the primary becomes right and the secondary becomes left.
- Connect the power cords to both the primary and secondary speakers.
- Turn the product on.
- Press the L/R SWAP button on the rear of the primary speaker.
- Check the primary speaker’s front display. “Speaker R” means the primary is assigned to the right channel and the secondary to the left.
- To restore the factory assignment, repeat the procedure. “Speaker L” means the primary is assigned left.
Yamaha says settings can also be changed through the MusicCast Controller app during or after initial setup. If you swap the speakers or change their positions, Yamaha recommends running YPAO through the app. These steps and that calibration recommendation apply to the NX-70A; do not assume another model has the same button, app, or feature. Yamaha NX-70A manual: swapping the left and right speakers; Yamaha NX-70A manual: MusicCast Controller and YPAO.

How to identify the right control on your system
- Find the exact brand and model on the speaker, receiver, or its documentation.
- Look up the control in that model’s manual. Check whether it changes channel assignment, playback mode, output selection, or a sound setting.
- After changing a left/right assignment, play a track or test signal with clear left/right information and confirm that each channel comes from the intended side. Use any on-device confirmation the manufacturer documents.
- If you moved the speakers, check the manufacturer’s calibration guidance. For the NX-70A, Yamaha recommends YPAO through MusicCast Controller after a swap or position change.
What to check before using a speaker selector
Selector and amplifier instructions are product-specific. OEM Systems says its SW-4SPKR supports up to four pairs of 8-ohm speakers and uses individual selector buttons to turn pairs on or off. For individual pair volume, its manual calls for one impedance-matching volume control per pair. Follow the selector’s manual and your amplifier’s guidance rather than applying the NX-70A channel-swap procedure. OEM Systems SW-4SPKR manual.

A swap changes configuration, not sound quality by itself. The documented instructions explain which channels or outputs play; they do not establish a universal sound-quality benefit. Set the channels to match your listening position and the system’s intended layout, then use the manufacturer’s calibration guidance if applicable.
