Functions
• Volume control: The volume control provides 25 attenuation positions: from 0 dB to –17.5 dB in 1.25 dB steps, from –17.5 dB to –25 dB in 2.5 dB steps, from –25 dB to –36.25 dB in 3.75 dB steps and with settings for –41.25 dB, –50 dB, –60 dB and –∞. A balance function can be implemented by controlling the left and right channels independently. • Equalizer: The equalizer function supports ±10 dB control in 2 dB steps in each of the five bands.
