Stereo amplifier with level controls AMP 2.2, Visaton

Stereo amplifier with level controls, e.g. for multimedia applications. Suitable for use with small loudspeakers with impedances of 4 to 8 ohms. Robust metal housing with two fixing lugs. Can be connected directly to the line out or headphones socket of a PC audio card, while the input sensitivity is regulated via the level control. Power supply (12 V) is via a mains adapter (not supplied) or the computer's on-board power supply. Short-circuit proof.

Power output (sine, 1% / 5% / 10% THD) 2 x 2.1 / 3.1 / 3.3 W (4 Ohm)
2 x 1.6 / 1.9 / 2.1 W (8 Ohm)
Input voltage (full conduction) 60 mV
Output impedance 1.1 Ohm
SNR 61 dB (A) / 59 dB (ext)
Frequency response (3 dB) 40 Hz–40 kHz
Terminal In-/Output jack 3.5 mm stereo
Terminal DC 5.4 mm outer diam. ()
2.1 mm inner diam. (+)
Net weight 0,178 kg
Temperature range 10 ... 50 °C

Different signal-to-noise ratio
Different input sensitivity for full conduction
For mobile audio application (mobile phone, MP3 player etc.) we recommend the AMP 2.2, for non-portable products (CD player, computer) we recommend the AMP 2.2 LN.
