The Taga Harmony TA-600MULTI installation amplifier supports playing different music in four independent stereo zones, with a separate source selection, volume control, and bass and treble adjustment for each zone. It is suitable for multi-room audio systems and for simultaneous transmission of voice announcements to selected zones. The toroidal transformer is rated at 200 W, and the amplifier uses Class A/B circuitry.

The USB port plays MP3, WMA, WAV, and APE files from a flash drive. The front panel features a 3.5 mm stereo input for connecting a smartphone, tablet, or laptop, while the rear stereo RCA input connects additional analog devices. Speaker pairs with an impedance of 4–16 Ω are supported in each zone.
