Send Main outputs from Motu Microbook (+4 dB signal) to Yamaha 10/2 Line channel 5/6, and set Gain to the grey area (+4 dB). The Level on 5/6 should be near 95%.
You may then connect ST OUT (+4dBu signal) to Genelec 8030 and set volume on Genelec to 10am from the left (0).
Ideal volume on Yamaha 10/2 would be ST 2pm and C/R volume, 11:30am.
Turn off all input volume on mixer – mic, esp guitar input on mixer as it has noise.
Microbook MAIN OUT is .. +4 dBu line . so feed to 5/6 LINE , and choose Gain +4 (white area). Manual says ST CH LINE INPUT for 5/6 = GAIN range = +10 to -34.
● “Consumer” gear (such as home audio equipment) usually has line inputs and outputs with a nominal
(average) level of –10 dB.
● Professional audio gear usually has line inputs and outputs with a nominal level of +4 dB.
● You should always feed –10 dB inputs with a –10 dB signal. If you feed a +4 dB signal into a –10 dB
input you are likely to overload the input.
● You should always feed +4 dB inputs with a +4 dB signal. A –10 dB signal is too small for a +4 dB
input, and will result in less-than-optimum performance.
● Many professional and semi-professional devices have level switches on the inputs and/or outputs
that let you select –10 or +4 dB. Be sure to set these switches to match the level of the connected
● Inputs that feature a “Gain” control—such as the mono-channel inputs on your Yamaha mixer—will
accept a very wide range of input levels because the control can be used to match the input’s sensitivity
to the signal. More on this later.
