Product description

QTX KA-2 (AVSL) is a two-channel stereo amplifier that has 15 watts of continuous power per two channels at 8 ohms impedance and 25 watts per each channel at 4 ohms impedance. The input sensitivity of the line source is 500mV, and the unbalanced microphone source is 2mV.

The peak output power of the amplifier at 8Ω is 2 x 30W and 2 x 50W at 4Ω. The rear panel of the KA-2 is equipped with 3 line inputs (6 x RCA) and one karaoke input (2 x RCA). There's also an output spring clip terminal for loudspeakers.

The front panel of the solid amplifier with a metal housing has two 6.3mm TRS microphone inputs. The remaining space is used for functional knobs - the large knob on the right is used to select the sound source and its mirror image knob adjusts the overall volume (Master). The smaller knobs are used to adjust the echo effect and volume levels for 1 and 2 microphone sources. The next three adjust the balance between the left and right side and set the treble and bass parameters.

The universal stereo QTX KA-2 amplifier weighs less than 2 kilograms. The product is available at the SQM Rental House.
