10,12:Gain 2, Gain 1. Use these controls to set the input gain level for the corresponding input jack. These controls set the level of the input signal and serve as the amplifier’s volume controls. 14: AC Line Cord. (Rear panel, not shown) The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power, and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection. 1 2 3 4 5 6 7 8 9 10 11 12 13 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. For short runs, (STP201, 3' STP202, 6' STP203, 9') to effect to "OUT" jack "IN" effect jack RINGTIP TIP = RETURN RING = SEND SLEEVE = GROUND For longer runs, use use Crate's STP201, Crate's YPP117 stereoSTP202 or STP203 to-mono 1/4" adapter adapter to connect an and two mono 1/4" effects device to the signal cables to connect Insert jack: an effects device to the Insert jack: TIP = RETURN RING = SEND SLEEVE = GROUND (YPP117) RINGTIP External Effect to effect "OUT" jack (1/4"-TO-1/4" MONO CABLES) to effect "IN" jack External Effect “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. AMP 1: AMP 2: AMP 1: AMP 2: LINE OUT INSERT CA30D Acoustic Amplifier The DSP Section: The CA30D features Crate’s DSP Digital Signal Processing. Use the Effects Mode control (#5) to select which type of effect will be applied to the amp’s output signal. Use the Effects Level control (#4) to adjust the level of the effect. 4 5 The chart below lists the names of the effects as they appear on the amlifier and a description of their settings: Effect Name Description Bypass Signal processing is turned off Slap Short slapback, without regeneration Delay Medium slapback, with regeneration Echo Long delay, with regeneration Chorus Light chorus effect - medium-slow speed Rotary Simulated “Leslie Speaker” tremolo Cho/Hall Light chorus, with moderate reverberation Room Moderate reverberation Hall Heavy reverberation CA30D Acoustic Amplifier The Tilt Back Feature: There are instances when you may need to tilt the amplifier back to better project its sound towards your ears (as a near-field monitor) or towards your audience (for better coverage). The CA15 features a tilt back device underneath its cabinet for this purpose. To utilize this tilt back feature, refer to the illustration below and follow these simple steps: 1 2 3 Carefully lean the cabinet back - until the front of the cabinet is several inches off the floor. Pull the tilt back bar down (to unlock it from its holder) and swing it forward until it locks into place. Lower the front of the amplifier until it rests on the tilt back bar. (To return the bar to its traveling position, reverse these steps) 1 2 3 CAUTIONS: Avoid trapping your hand under the tilt back bar. Always make sure the bar is securely locked in place before lowering the amplifier. Do not sit on or rest your foot on the ampli- fier when it is in the tilt back position.
