Connecting an Additional Subwoofer
If you have a large monitoring environment requiring greater subwoofer sound
pressure, you can connect as many SBX cabinets as desired in a daisy chain.
Simply connect the Extra Sub Output (located in the Output section) to 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 want 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” in 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) indicates the current status of the Auto
Power circuit, glowing amber when in Standby 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 Power On/Off switch to the “Off” position. When Auto
Power Mode is turned off you must turn the SBX on or off manually using the
Power switch.
Note: If you intend not to use the system for a long period of time (such as a
vacation), it is advisable to manually turn the system off via the Power switch
.
Setting the HPF Bypass Switch
In normal operation, the HPF Bypass switch should be left in the “Off” position.
When the HPF Bypass switch is in the Of
f position, the SBX Stereo Bass
Management System is operational. In this case, the “Satellites” control knob,
which sets the cutoff frequency of the HPF, is also operational.
When you want to bypass the SBX Stereo Bass Management System, engage
the HPF Bypass by switching it to the “On” position. This will defeat the
“Satellites” control knob and the HPF.
