Home stereo amplifier with Bluetooth

The Corn Electronics PDA4BU is a multi-channel receiver that delivers 200 watt peak output and 20 Watt x 2 at 8 Ohm RMS for home theatre or karaoke use. Bluetooth provides a 40+ ft wireless range for streaming from phones, tablets or laptops. Nine wired inputs cover optical, phono, coaxial, USB, SD, aux, two RCA pairs and dual 1/4" microphone jacks. A headphone output and FM radio with auto-scan complete the feature set.

Sustained output at rated impedance

The amplifier is specified at 20 Watt per channel into 8 Ohm RMS, which represents its continuous power capability rather than a short-term peak. At 4 Ohm the unit can reach 25 watt max power for dynamic passages. Thermal design and ventilation are built to maintain this rated output during extended listening sessions without triggering protection circuits.

Two-channel RMS power at 8 Ohm

The single figure that determines suitability is the 20 Watt x 2 RMS rating into 8 Ohm, which sets the realistic loudness ceiling for typical home speakers. Buyers needing higher continuous power for larger rooms or lower-impedance loads will find this amplifier insufficient. The 200 watt peak and 25 watt at 4 Ohm figures are useful for headroom but do not replace the RMS rating as the design benchmark.

Questions about this item

How loud does the 200 W amplifier run after hours of karaoke use?

The unit delivers 20 W per channel at 8 Ω RMS and 25 W at 4 Ω max, so it stays cool during long sessions with no fan noise mentioned.

Which speakers and sources do I need to connect to the optical, phono, coaxial, RCA, aux, USB, SD, and mic inputs?

Bring passive speakers rated for 4–8 Ω, plus any mix of turntable, CD player, TV, phone, or microphones — the receiver provides all listed inputs and a headphone jack.

Will the Bluetooth 40 ft range and analog inputs work with my older turntable and wired speakers?

Yes, the phono and RCA inputs accept legacy sources, while Bluetooth streams from modern devices up to 40 ft away, and the speaker terminals drive your existing passive speakers.
