4.1-Channel Amplifier S-299

The S-299 is a compact digital amplifier delivering 40 W RMS per channel across four speaker outputs plus a dedicated subwoofer line output. It accepts power from a 12 V DC source and integrates two YD7377 processing chips for low-distortion playback. Bluetooth 5.0, USB, SD/MMC, AUX and RCA inputs provide multiple ways to feed audio into a home-theatre, desktop or vehicle sound system.

Home-audio builders needing four passive speakers

This unit suits anyone assembling a 4.1 speaker set driven from a single box with independent volume groups for the main channels and the subwoofer. It is not for installations that require more than four powered speaker channels, built-in radio reception, Wi-Fi streaming or multi-room synchronisation.

40 W RMS per channel into 4–8 Ω loads

The rated continuous output of 40 W per channel determines whether your passive speakers will reach the desired volume without distortion. Match this figure to the speaker sensitivity and room size before purchase.

Questions about this item

What does Bluetooth 5.0 limit in real use?

The Bluetooth 5.0 link works up to five metres and carries audio from phones, tablets or TVs without cables.

What space and power does the S-299 need to fit?

It runs on a DC 12 V five-amp supply and accepts four 4-to-8-ohm passive speakers plus an active subwoofer with no power limit.

How is the S-299 hooked up, and what step trips people up?

Connect the 12 V supply, wire four passive speakers to the speaker terminals, link an active subwoofer via the sub-out RCA, then pair Bluetooth or plug USB, SD, AUX or RCA sources; the common mistake is forgetting the subwoofer needs its own mains power.
