SB166XL
2 IN / 6 OUT Digital Speaker Management System
The SB-166XL uses an Auto-Limit rising and reversing circuit & processes an auto expander/gate, which automatically adjusts expansion according to the program material, thus eliminating the noise floor during quiet sessions or music pauses. The Stereo / Mono operation switch makes it easy to adjust the unification effects between L/R channels. Input level selection (+4 / -10dBu); LED indicator gives a true display of the signal level for easy operation and adjustment.
