These functions result in greatly improved clarity and lower distortion of the sound that is produced. The block diagram below shows the primary functional blocks of the K235. The line-level audio signals, either balanced or unbalanced, enter from the left and are received and buffered by the ‘Balanced/Unbalanced Input Stage’... - Page 6 Output Stages’. Again, both the balanced and unbalanced outputs are active at all times. But, again, this is a shared circuit between balanced and unbalanced outputs and only one set or the other should ever be connected at any given time. SUBLIME ACOUSTIC MODEL K235...

- Page 8 Back-EMF Distortion: Back EMF, or back electro-motive force, is the voltage created by the speaker winding when the momentum of the cone causes the winding to continue moving relative to the speaker magnet. This voltage, particularly from the woofer, flows backward through the SUBLIME ACOUSTIC MODEL K235...

Active crossover circuits, like those used in the K235 , on the other hand, are built from the highest quality operational amplifiers (op-amps) and the filter functions are applied to the line-level preamp input signals instead of the high voltage amplifier outputs. -

3-Way or 2-Way Active Crossover Configuration The K235 is primarily designed as a 3-Way crossover, but it can be configured as a 2-Way crossover by setting the ‘Mode’ switch inside the access panel on the bottom of the unit (see diagram below). -
Page 11: Configuring The Crossover Frequencies
Configuring the Crossover Frequencies The subwoofer and mid/high crossover frequencies are controlled by the values of two ‘XO Modules’ inside the K235. These are accessible through an access panel on the bottom of the chassis. Normally these will be pre-installed at the factory and you may never need to do anything with regard to the XO modules. - Page 12 XO Module and Setting Selection SUBLIME ACOUSTIC MODEL K235...

The K235 can sometimes send a loud ‘thump’ to the amplifier when you power it up or power it down. To protect your speakers, be sure to power up the K235 before you power up your amplifiers. And power down your amplifiers first, then power down the K235. -

For 4-way and 5 way operation, two K235’s are cascaded to create the additional channels. Always use balanced XLR patch cables to connect the two K235’s as shown. - Page 16 SUBLIME ACOUSTIC MODEL K235...
