Hardware installation & connection
BTQ-VM/SG/SL mounting
Mount the BTQ-VM4/8 controller in any standard
19-inch 2U audio equipment rack using the supplied

SG8 secondary unit is similar to installing a BTQ-
VM4/VM8, except the secondary units are installed in

Consider leaving enough ventilation space above and
below the unit. Do not mount the controller directly
above the heat generating devices like power supplies
or power amplifiers.
