Slave Thru
The input is passively fed to the Slave Thru (8) output for bi-wiring applications.
Gain Trim
The input can be lowered with the Gain TRIM switch (9) from 0 dB to -5.5 dB in 0.5 dB steps.
This is helpful if you want to use multi speaker sets or speakers in a bi-wiring application. It
allows to level speakers with different efficiency to equal loudness.
