This is one of four manuals I have downloaded recently.
Purchase was very straight forward and the authorising email arrived in about 4 hours.
The quality of the scan is good. Print is clear and square to the page edges.
Exactly as advertized. High quality digital copy of the Nak 610 user manual. Easy download and access. Highly recommended.
Text excerpt from page 24 (click to view)
For the best possible surround sound, all the speakers other than the subwoofer should be the same distance from the listening position (A). However, if necessary, this system allows you to place the centre speaker up to 1.6 meters (5 feet) closer (B) and the rear speakers up to 4.6 meters (15 feet) closer (C) to the listening position. The front speakers can be placed from 1.0 to 15.0 meters (3 to 50 feet) (A) from the listening position. You can place the subwoofer in any position. You can place the rear speakers either behind you or to the side, depending on the shape of your room, etc.
When the rear speakers are placed to the side When the rear speakers are placed behind you
Do not place the centre and rear speakers farther away from the listening position than the front speakers.
Specifying the speaker parameters
To obtain the best possible surround sound, first specify the distance of the speakers from your listening position, then set the balance and level. Use the test tone to adjust the speaker volumes to the same level. You may adjust the speaker parameters using SPEAKER SETUP in the setup display (page 67).
