This is necessary to ensure proper compliance with European Standards for Electromagnetic Compatibility. Pin 1 carries no signal voltages or currents and is provided purely for screening purposes. It should not be connected to either pin 2 or pin 3. Source Unbalanced Pin 2 Hot If the equipment providing the audio signal has an unbalanced output, then the interconnecting audio cable should be wired so that the hot output of the source is connected to pin 2 of speaker...

This can be used as a monitoring function, as it allows you to easily switch between a 2 and 3-way monitoring set up. There is a green LED that indicates when the SB10 is bypassed. Gain The sub bass amplifier gain can be adjusted with the recessed pot in the front panel by using a flat bladed screwdriver. -

This switch should be used with caution. The SB10 should never be used without any low pass filters. To use the SB10 without any low pass filters is likely to cause damage to the drive unit. This is because the cabinet has a large resonance that is out of the normal operating bandwidth. - Page 10 40cm Diagram shows a symetrical room layout. The system is set up centrally in the room, therefore the SB10 has been placed closer to the left hand monitors, which allows the SB10 to be away from the room's centre. Fig 1...
- Page 11 Controller. The left and right outputs of the controller are connected to the inputs of the left and right monitors. Connect the SB10 Controller to the SB10 with as short a length of good quality speaker cable as is practical. It is important that speaker cables are twisted, shielded or at least run closely paralleled to reduce loops conducting RF currents.

Disconnect the full range cabinets, send the pink noise to both sub woofers. Reverse polarity on the SB10 controller that is not the master. Adjust the phase on this controller to obtain the lowest output of the combined sub woofers. Switch the polarity on the same controller back to its original position, the phase of the two sub woofers is accurately adjusted. -
