This is the original Cooper Sound Systems CS104-4T Direct Out upgrade kit manufactured by us.
Features include:

• Each Output is individually pre or post fader, selectable by board mounted switches.
• Draws power only when direct out cable is plugged in.
  Balanced line level outputs.
• A 12 pin connector replaces the Mix In connector (TA3 connector located on the right side toward the front) and includes pins for mix in so this function works as it did before the upgrade.
• This is available either installed in your mixer or as a kit to be user installed.
• Direct Out cables are ordered separately. Several common Direct Out cables are available on our website or you may wish to have a custom cable made by us.  For a custom cable, you will need to specify length and connector types, etc.
• Installation is NOT included in the price.  Installation costs are $175.00 for most CS 104 mixers later than series 2.  The series 1 and 2 are slightly higher in cost. Please contact us prior to shipping your mixer to us if you want us to install the 104-4T board. .
