Features

• Series of pin compatible power amplifiers ranging from

20 W × 2 channels to 120 W × 2 channels (10%/1 kHz)

devices. The same printed circuit board can be used

depending on the output power grade.

• The pin arrangement is compatible with that of the 3-

channel STK402-200 series. This means that 3-channel

printed circuit boards can also be used for 2-channel

products.

• Miniature packages

— 15 W/ch to 40 W/ch (THD = 0.4%, f = 20 Hz to

20 kHz); 46.6 mm × 25.5 mm × 8.5 mm *

— 50 W/ch to 80 W/ch (THD = 0.4%, f = 20 Hz to

20 kHz); 59.2 mm × 31.0 mm × 8.5 mm *

*: Not including the pins.

• Output load impedance: RL = 6 Ω

• Allowable load shorted time: 0.3 seconds

• Supports the use of standby, muting, and load shorting

protection circuits.
