If the input signal is subject to filtering, the filtering circuit may add noise to the signal. A low cost phono stage will kill most of the details and delicacy of the expensive LP player, and therefore a high quality RIAA amplifier module is required. 1) can extend an amp's bass response but, in excess, can make it sound woofy, waste power on frequencies it can't produce, or even unstable. Frequency Difference Divider The opposite of a frequency difference multiplier? Low-Cost Phase Noise Measurement Phase Noise, Harmonics and Sub-Harmonics. In pursuit of the intangible musical quality that breathes life into high-fidelity audio, the world's largest sound company presents the C-5000 preamplifier. This can be a huge problem if your amp is mounted in the same air space as the speakers it drives. A discrete components topology, using + and - 24V supply rails was chosen, keeping the transistor count to the minimum, but still allowing low noise, very low distortion and high input overload margin. This creates a direct feedback path from the speaker into the amplifier circuit, so when you turn the amplifier up, you hear a squeal. The PR-101 Stereo Preamplifier is a preamplifier kit with a remote control that you can customize. Some say it has little or no effect while others claim it's critical to have a high quality 12AT7 in this slot.
