SPK- SOUND FEAST 450 ZEBRONICS PORTABLE BLUETOOTH SPEAKER (USPK 103)

The available playback modes are Bluetooth (BT v5.3), USB, and AUX.

For AUX mode, plug a 3.5mm AUX cable directly into the input port on the back of the speaker. For USB mode, connect a compatible USB flash drive (up to 32GB, formatted to FAT32) containing supported MP3, WAV, or FLAC files into the rear USB port. The speaker typically detects connected media automatically ; if it does not, short-press the M (Mode) button to cycle to your target input manually.

Yes, you can connect a wired microphone by plugging a standard 6.3mm microphone jack into the dedicated MIC input port located on the back panel of the speaker.

To adjust the echo level, first double-press the M (Mode) button to enter the microphone echo adjustment mode. Once inside this mode, press the + or - buttons to increase or decrease the echo depth.

Turn on two identical ZEB SOUND FEAST 450 speakers and ensure both are in Bluetooth mode. Long-press the Play/Pause (▷) button on one of the speakers to initiate TWS mode. The speakers will automatically search for and connect to each other. Once successfully paired, locate and select "ZEB-SoundFeast 450" on your mobile device's Bluetooth menu to stream synchronized audio.

To perform a hardware reset on the device, locate the physical RESET pinhole positioned on the rear interface panel next to the AUX port and gently press inside it. (Note: The raw draft suggestion to long-press the non-existent "MENU" button is incorrect; the physical hardware pinhole must be used).

While a short press on the BASS button triggers the bass boost effect , a long press on the BASS button allows you to cycle through the different RGB LED illumination configurations or turn the lights off entirely.

The top control panel features 4 status indicator lights that display real-time capacity: 4 Lights Solid ON: 100% Battery. 3 Lights Solid ON: 75% Battery. 2 Lights Solid ON: 50% Battery. 1 Light Flashing: Below 25% Battery (device requires charging).
