How to use

Place the Stanmore III on a stable surface, connect a power source and select the desired input mode. For Bluetooth streaming, enable Bluetooth on your source device and pair it with the speaker; the multi-host feature allows a second device to be paired so you can switch between sources. For wired connections, connect an RCA or optical cable from your audio source to the corresponding input on the speaker or connected amplifier. Use the front knobs to set volume and adjust tonal balance to suit the room acoustics and listening preference.

Recommendations

Position the speaker at ear level for optimal near-field listening and leave some clearance from walls to reduce low-frequency buildup. When using the optical input for TV audio, set the TV’s audio output to a compatible digital format and adjust speaker volume to match other system components. For stable Bluetooth performance, keep the paired device within typical Bluetooth range and minimize obstacles between the device and the speaker.
