CA30D Acoustic Amplifier Introduction: Congratulations! You are now the proud owner of one of Crate’s latest contributions to the world of acoustic amplification, the CA30D. This compact amplifier delivers a strong 30 watts of clear musical power and incorporates two inputs (each with a gain control), three bands of equalization, plus Crate’s Contour control for added tonal flexibility. The CA30D features Crate’s DSP digital reverb and effects, a front panel Insert (effects loop), and a Line Out jack.
CA30D Acoustic Amplifier The Front Panel: 1 2 3 4 5 6 7 1: Power. Use this switch to apply power to the amplifier: the amp is on when the top of the switch is depressed, off when the bottom of the switch is depressed. The switch illuminates when the amp is on. 2: Line Out. Use this jack to connect a high impedance, unbalanced line level signal to a house sound board, a recording console or another amplifier. 3: Insert. Use this jack to add external effects to the signal.
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.
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.
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 Carefully lean the cabinet back - until the front of the cabinet is several inches off the floor.
