INTRODUCTION
Thank you for your purchase of the ISP Technologies 300-watt (RMS) Vector
112! This new guitar subwoofer cabinet offers the same world-renowned
VECTOR active guitar subwoofer technology in a smaller, more lightweight
package. Inside is a 12" neo woofer with 300 watts (program) available to
deliver the thunderous low end that you can only find with the Vector subwoofer
system. The concept of the Vector 112 corresponds with the Vector SL guitar
subwoofer in terms of easy hook-up and user-friendly operation. Just plug in
and play. You can literally feel the power of the Vector 112's low-end shake your
bones and yet the highs for your external cabinet are high passed and remain
focused and accurate. Simply connect any combo amplifier and get ready to
hear all the low end you have been missing and the best part, you can add the
Vector 112 to your guitar rig at an amazing low price!
Please read this manual carefully for a through explanation of the Vector 112 and its
functions.
