Need help?Do you have a question about the Pyle PP999 and is the answer not in the manual?
The Pyle PP999 is a compact phono turntable preamplifier designed to convert phono-level audio signals to line-level signals, making them compatible with a wider range of audio equipment such as receivers and amplifiers. This ultra-low noise audio pre-amplifier is equipped with a 12-volt power adaptor and is suitable for both on-stage and in-studio performances.
The primary function of the PP999 is to amplify the weak phono-level output from a turntable or record player to a stronger, more manageable line-level signal. This is crucial because phono signals are typically much lower in voltage than line-level signals, and without proper amplification, they would sound very quiet or distorted when connected directly to an amplifier or receiver's line-level input. The PP999's ultra-low noise audio conditioning circuitry ensures that the boosted audio signal maintains high fidelity and clarity, minimizing unwanted noise and interference. By providing voltage gain, the preamplifier helps to prepare the audio signal for further processing by other audio components, allowing for easier adjustment of recording levels and volumes from various sources and instruments. The device is designed for simple electric plug-in operation and features dedicated RCA (L/R) audio connectors for both input and output. Its integrated circuitry is specifically designed to accommodate magnetic pickups, which are commonly found in turntables. The PP999 offers universal compatibility, making it suitable for use with turntables, mixers, and other audio equipment. Positioning the preamplifier close to the audio source is recommended to further reduce potential noise and interference.
These specifications highlight the PP999's capability to deliver a clean and robust audio signal. A 70 dB S/N ratio indicates a good signal-to-noise performance, meaning the desired audio signal is significantly louder than any background noise. The low T.H.D. of 0.08% suggests minimal distortion, ensuring that the amplified audio remains true to the original source. The broad frequency response of 20-20kHz covers the full range of human hearing, ensuring that all audible frequencies are reproduced accurately. The input sensitivity and impedance are tailored for phono cartridges, specifically 3 mV at 50K Ohms, which is a common specification for moving magnet (MM) cartridges. The engineered metal alloy housing provides durability and helps shield the internal components from external interference.
The Pyle PP999 is designed for straightforward use, making it an accessible tool for musicians, producers, and audio enthusiasts.
While the manual does not explicitly detail specific maintenance procedures, the design and construction imply certain aspects:
In summary, the Pyle PP999 is a reliable and user-friendly compact phono turntable preamplifier that effectively bridges the gap between turntables and line-level audio inputs. Its robust technical specifications and ease of use make it a valuable component for enhancing audio quality and system compatibility.
