Bose 802-C System Controller Engineer Checked -LOT 1

  

Bose 802c System Controller - LOT 1. The 802 C System Controller is a sophisticated signal processing device that combines the functions of three equalizers, an automatic switching circuit, and an electronic crossover.

The 802C system controller automatically selects the proper crossover function and equalization curve for a given system application through use of a switching network operating in conjunction with the unit's output jacks. In addition to signal routing based on equalization requirements, the switching network indicates mode of operation on its front panel. The front panel also includes high-cut and low-cut switches which decrease line output by 4dB at 55Hz and by 10dB at 16kHz. Sharp subsonic and ultrasonic band-limiting filters reduce power waste, stage noise, high-frequency instability, and interference.

Without the 802c controller your 802's Mk2 / 302 speakers will not perform optimally as designed. Bose offered an optional 1u rackmount kit at extra cost, see other listing - LOT 1. Here we have for sale a vintage.

That retains its black frequency selector buttons that makes it easier to change frequency. The 802c is now a vintage item and as such all of these units require component checks and. I paid to have qualified electronics engineers Perton Electronic carry out pre listing. And this was completed just prior to listing.

This Bose Controller has been. Perton Electronics have now passed this 802c as fully operational and in full working condition. I recommend viewing their Perton Electronics YT channel, mend it mark, you will see the advanced testing equipment they use alongside the care, attention and knowledge that is applied to repair and servicing on a wide variety of electronic items.

This used 802c controller is in reasonable aesthetic condition. And retains its top cover connection diagram on the lid, please refer to photographs which form part of the description.

I note there are surface scratches to the lid and to the underside of the unit. Fortunately the connection graphic is clearly visible.

I have replaced/ fitted 4 new rubber feet and have cleaned the unit with a specialist case cleaner. It has an integral power lead that terminates in a 3 pin plug. I will carefully and securely box the 802c in foam for added protection of the unit and the package will be sent insured / signed for and is reflected in the postal charge. The item will be carefully boxed in foam and then placed inside a larger box to offer as much protection through the post and I also take photographs of the boxed item and serial number in its packaging.

From this you can see the care I take to ensure the item is received in the condition it was sent.
