CA30D Acoustic Amplifier
Connecting to the Insert Jack:
The Insert jack (#3) allows you to patch external effects into the amplifier just prior to
its power amp stage. To connect the effect to the Insert jack use Crate’s STP201, STP202,
or STP203 stereo-to-mono Y-cord, ar an adapter such as Crate’s YPP117 and two shielded
signal cables terminated with 1/4” tip/sleeve connectors as shown below.

“Chaining” Amplifiers:
The Line Out jack (#2) on one CA30D can be connected to the Insert jack of another, to
chain the amps together as shown below. (This frees up the Input jacks of the second
amplifier.) Use a shielded cable terminated with 1/4” tip/sleeve connectors as shown.
