DIGITECH Audio

Product Overview

The DIGITECH Audio AC-1751 is a 60W Speaker Attenuator Wall Plate designed for wall mounting. It fits all standard Australian electrical junction boxes, whether surface or recessed. With a power rating of 60 watts RMS, it is suitable for most applications, excluding those requiring very high power. The unit is constructed to high standards, ensuring quality electronic components and reliable performance. A key advantage is that at full volume, the Volume Control is not in circuit. In the OFF position, it is open circuit, meaning there is no load on the amplifier. When used with a 60-watt RMS amplifier output, the Volume Control dissipates minimal heat across all settings.

Specifications

Wiring Diagram

The unit features input terminals labeled 'AMP' with 'R+' and 'R-' for the right channel positive and negative, and 'L+' and 'L-' for the left channel positive and negative. The output terminals are labeled 'SPK OUTPUT' with corresponding 'R+'/'R-' and 'L+'/'L-' connections for speakers. The diagram illustrates connecting the amplifier's positive and negative outputs to the corresponding input terminals on the attenuator, and then connecting the attenuator's output terminals to the speaker's positive and negative terminals.

Tips for Optimal Performance

• The Volume Control does not eliminate the need for impedance matching in installations with multiple speakers.
• Long cable runs can negatively impact sound quality.
• Ensure that good quality audio cable is used to maintain sound quality.
