11 Control Definitions Alrighty, here comes the fun stuff. We’ re going to break this down to it simp lest form so that there is no way you can possibly do any damage in t he installation process to your audio system.
12 Crossovers (continued) HAWKINS – This is a patented circuit devel oped by Soundstream many years ago. Hawkins has 2 controls but 3 functions. One of the controls is t he boost and it is from 0-10dB. The second control is the frequency. What- ever frequency you select will be the frequency that is controlled by the adjus table boost.
13 Balanced Signal Inputs – Using our BLT Balanced Line Transmitters, you can achieve balanced, noise-free signal transfer. This is a MUST and no-brainer for any audiophile , sound quality competitor, or anybody serious about their music. CH1&2 Signal Mode – There are two options here fo r the signal processing.
