ToneWinner AD-7300PA+ 7-Channel Power Amplifier

7-Channel, 310W-per-Channel Power Amplifier for Dedicated Home Cinemas

The ToneWinner AD-7300PA+ is a seven-channel Class AB power amplifier built to drive a full 7.1 or 5.1.2 cinema system from a single chassis. Each channel delivers 310W RMS into 8 ohms (515W into 4 ohms), so every speaker in the room, from the fronts to the surrounds and heights, gets power in reserve for loud, dynamic movie moments.

Seven independent modular amplifier boards and 42 high-power ON Semiconductor transistors keep each channel clean and controlled. Every channel has both balanced XLR and unbalanced RCA inputs, so it pairs easily with an AV processor or preamp, and a trigger port lets it switch on and off with the rest of your system.

A blue illuminated meter on the front panel, a dimmer control and full protection against over-voltage, over-heating, over-load, over-current and short circuit round out the package. It is a large, heavy unit (about 25kg), so plan rack space and ventilation in advance.

Best suited for:
Dedicated home theatres, large living rooms and high-output AV installations that use a separate processor or preamp.
