Operation

Connecting an Additional Subwoofer

 

If you have a large monitoring environment requiring greater subwoofer sound

pressure, you can connect as many SBX

as desired in a daisy chain.

Simply connect the Extra Sub Outp t (locatedcabinetsthe Output section) the Input-L

or Input-R input of second SBX (you may use the Extra Sub Output to connect to

another brand of subwoofer). In this instance, you will ant to have the HPF

Bypass switch set to “On” on the second SBX subwoofer so that bass

management is not repeated in the second sub.

 

Operation

Power Modes

 

The SBX’s main Power switch (#12) must be switched “On” order for the SBX

to operate. The subwoofer is designed to operate continuously in Power “on”

mode. (The SBX uses less than 3 VA in power mode.)

When the Auto Power mode is engaged, in conjunction with Power “on”, the

subwoofer automatically becomes operational when a signal is present and

returns to Standby mode when a signal has not been detected for five minutes.

To operate in Auto Power mode, turn the Auto Power On/Off switch (#7) to the

“On” position. The Power mode LED (#1)

the current status of the Auto

Power circuit, glowing amber whenindicatesStandby and green when fully operational. When Auto Power is engaged, it is not necessary to turn the Power switch on or off each time you wish to use the SBX.

In special situations where you intend to play the system at very low volume or if Auto Power mode will not meet your application for any other reason, you can switch the Auto Poffwer On/Off switch to the “Off” position. When Auto Power Mode is turned you must turn the SBX on or off manually using the

switch.

If you intend not to use the system for a long period of time (such as a vacation),Note: it is advisable to manually turn the system off via the Power switch.

SettingIn normaltheoperation,HPF Bypassthe HPFSwitchBypass switch should be left in the “Off” position. When the HPF Bypass switch is in the Off position, the SBX Stereo Bass Management System is operatiofnal. In this case, the “Satellites” control knob,
