(please refer application circuit diagram.) 4. about hi-voltage function about logic of hi-voltage function is follow as. hi-voltage on/off hi-voltage on ? though the level of amplification in the output-unit is controlled with level shift (select address 01hex, d3), it becomes a +6db fixation under the condition of hi-voltage function is on. ? under the condition of hi-voltage function is off, 0db/+3db switching is possible by the setup of level shift. ? under the condition of hi-voltage function is off, bias-voltage is 4.15v regardless of the setup of level shift. ? the use of the external mute on the set side is recommended because shock noise by the dc step is made when on/off switching of the hi-voltage function is done. ? the initial condition of hi-voltage function is hi-voltage=on after a power supply is started) hivoltage on/off(select address 01hex, d2) 0 0 1 1 - level shift(select address 01hex, d3) 0 1 0 1 - level of amplification in the output-unit 0 3 6 6 [db] bias-voltage in the output-unit 4.15 4.15 6 6 [v] 2 in) 2 in (2fcr1 )(2fcr a(f) + = 0 a(f) g[db] f[hz] c[f] rin [ ] input s sh
