Description: Integrate the Module into Your Setup Easily incorporate the PA15 preamplifier into your audio chain to enhance system control. Adjustable Output Fine-tune the output levels to meet your system’s specific needs for optimal performance. Included Accessories The package comes with an RCA to 3.5mm TRS cable for added connectivity convenience. Understanding Gain Staging Gain staging, or gain structuring, is the process of setting the gain for each stage of amplification in a sound system. This ensures the best signal-to-noise ratio by minimizing noise and distortion while achieving the desired volume. Proper gain staging helps optimize the loudest peaks without clipping, requiring careful consideration of each system component. For example, in a setup with an iPad, a PA15 preamplifier, and an A2150 amplifier, you have multiple points to control gain. Begin by maximizing the volume on your input device, setting the amplifier’s trim to about 50%, and adjusting the PA15 up to around 80% to achieve the desired loudness. If additional volume is needed, adjust the amplifier trim. However, remember that increasing the amplifier or preamplifier levels raises the noise floor—the inherent signal noise from all the equipment. To maintain clarity, avoid exceeding 80% of the maximum volume on pre-amplifiers and amplifiers. This approach not only reduces noise but also prevents clipping, even if the system input is maxed out by the end user. Origin Acoustics’ low signal-to-noise ratio amplifiers ensure high performance, but adhering to this practice ensures consistent and reliable audio quality. Installation and Operation Step 1 Access the rear of the source (CD/DVD player, computer, etc.), preamp and amplifier(s). Locate the output jacks on the back of the source and the corresponding inputs on the preamp.Step 2 Connect the source to the preamp using the RCA or Auxiliary connectors. Push in the connectors from the audio outputs on the source to the appropriately-labeled inputs on the preamp (labeled L & R IN or AUX IN).Step 3 Find the RCA or Auxiliary preamp output cluster on the back of the preamp (labeled L & R OUT or AUX OUT). Find the corresponding RCA inputs (L/R IN) on the back of the amplifier(s). Plug the connector cables from the preamp outputs to the matching inputs on the amplifier.Step 4 Connect the preamp to the main power socket with the AC adapter. Press “ON” button to turn the preamp on. Tips Shorter speaker cable runs, at the expense of longer RCA runs, allows better power transfer to the speaker.
