POSITIONING YOUR SPEAKERS SUBWOOFER/AMPLIFIER Place the Subwoofer cabinet on the floor, preferably near a wall. Do not place it on a desktop or shelf. For maximum bass output, place the subwoofer near a corner. If the subwoofer is placed away from the intersection of two room surfaces, the maximum bass output will be reduced. Use the Bass Level control to adjust the bass output to your desired balance. Recommended Bass control settings for each type of location are shown.
CONNECTIONS Volume Control It is not necessary to connect the Volume Control if your audio signal source provides an output level adjustment. The volume control allows use with a source that do not A have volume control, or where the source’s volume control is inconvenient. A) If you are using the ST50 Desktop Stand with Newton Series MC50 or MC100 speakers, slide the Newton Series ST50 Desktop Stand – recommended for MC50 and MC100 satellites Volume Control onto the support strut on one of the stands.

2) Using the BassCube 821 system as a sound system for a component CD player. COMPONENT CD OUTPUT Typically, there are two RCA-type jacks (one red, one white) on the CD player. To connect to these OUTPUTS jacks, use the stereo signal cable with two RCA plugs on one end and a 3.5 mm stereo miniplug at RIGHT LEFT the other end. Connect the miniplug to LINE IN A of the BassCube 821 and the RCA plugs to your CD player’s red and white RCA jacks. Signal Cable One 3.
Speaker Connections To connect the speaker cables. The BassCube 821 will accept your choice of speaker wire up to AWG#16. We recommend at least AWG#18 for runs up to 12 feet, and AWG#16 for longer runs. Speaker wire is generally marked in some way to help identify the “+” and “–” conductors at each end. Sometimes this is done by printing on the jacket, a ribbon stripe molded in, or different color wires. Be certain to maintain the proper polarity at each connection.
OPERATION AND FINAL ADJUSTMENT 1) Use the Volume Control or the signal source control to vary output level. 2) Defeat or cancel any “tone control” or other sound adjustments within your audio program source. Portable CD players may have “bass boost” switches and many computer sound programs have audio adjustments concealed in drop-down menus. 3) If possible, play a variety of musical CDs with good deep bass content to judge the best setting of the Bass and Treble controls.
