Thank you for your purchase.  The NAD VISO speakers are designed to deliver 
high performance in many uses, and we hope they add much enjoyment to your 
listening life.

For detailed information on speaker positioning, NAD VISO DVD Receiver 
set-up and complete system configuration please refer to the 
comprehensive VISO TWENTY/VISO THIRTY Owner’s Manual at 

I.   QUICK START

A. Attach the supplied adhesive backed bumpers near the corners of the LR5’s 

and C20’s bottom surface to protect the finish of speakers and furnishings.

B. Position

 LR5 speakers

 as symmetrically as possible, at a comfortable 

distance from your seating position—slightly closer to each other than they 
are to you.  Position the 

C20 center channel

 directly above or underneath 

your TV screen.  (Keep its front as much in line as possible with the front of 
the picture.)  

C. Using standard lamp “zip cord” (18 gauge/1.0mm dia) wire or better, connect 

the Red (positive) binding post of each speaker to the Red terminal of your 
signal source on the channel. Similarly, connect Black (ground) on each 
speaker to Black on that channel's signal source.  (If the output of the signal 
source is via a proprietary cable with a jack at one end, connect the color-
coded wires at the other end of the cable to the speaker's similarly-coded 
posts.) 

Be sure to follow color-coding to make sure that your speakers 

are “in phase” for smoothest sound with deepest bass.

D. The loudest bass output from a subwoofer will come from corner placement. 

As you position the subwoofer outward from the corner along one wall or 
another, bass output diminishes somewhat, it also becomes more uniform 
throughout the room, with fewer of the “standing waves” that produce peaks 
and nulls at various points. Turn off all other components, and follow one of 
the connection diagrams. Connect the supplied power cord to the AC power 
socket, then plug the subwoofer into an active AC outlet. The same receptacle 
as the rest of your audio/video system or another on the same electrical 
circuit should be used to avoid ground hum. Set the subwoofer’s phase switch 
to 0° and volume switch to 0dB. Flip the Power Switch to the on position.
