Q2 Wi-Fi Internet Radio Support

Q. What is the audio specification of the Q2 Radio amplifier and speakers?

Answer:

The Q2 Radio uses a custom designed full range 2.4" 4 ohm drive unit chosen for good sensitivity and matched to the 140 Hz tuned port enclosure.

Biquad DSP filters are used to voice the sound, giving a smooth listening response and added bass extension from the speaker system.

The amplifier is a high efficiency Class AB BTL type, optimised for battery operation, giving typically less than 0.1% THD under normal operating conditions. The use of a Class AB rather than Class D type amplifier results in both lower noise and distortion.
