parks audio Puffin User Manual

Connect music source to Puffin input and Puffin output to stereo device. Ensure proper connections for audio playback.

Familiarize with the Standby button, Knob, and Select button for Puffin operation and settings adjustment.

Turn on the Puffin with low system volume. Allow a few seconds for initialization. Default gain is set for vinyl.

Select the 'CD' preset for CD players or line output devices for optimal amplification levels.

Keep system volume low when changing gain or presets. Use Standby as an emergency mute for loud surprises.

Adjusts audio volume, can serve as cue mute or signal attenuator. Offers levels from muted to maximum.

Pivots frequency response at 900Hz for warmer or brighter sound character, adjustable in 1dB steps.

Adjusts bass response with a corner frequency of 300Hz, allowing fine-tuning of low frequencies.

Adjusts treble response with a corner frequency of 3kHz, offering subtle control over high frequencies.

High frequency treble control (above 8kHz) for cartridge loading and taming bright sources.

4th order Butterworth filter to attenuate higher frequencies, reducing noise and adjusting response.

4th order Butterworth filter to attenuate lower frequencies, reducing rumble and resonances.

Select between stereo, mono, left, or right modes to optimize sound based on recording or preference.

Emulates analog sound characteristics like tube or tape distortion for unique sonic coloration.

Wide range of gain settings from -4dB to 72dB for matching various input sources.

Selectable input impedance of 47k or 200 ohms for optimizing cartridge performance and input matching.

Adjusts balance between left and right channels in 2dB steps for precise stereo imaging.

Fine-tunes left channel in +/- 0.3dB steps to perfectly match the right channel.

Offers Normal, Invert, and Mixed phase settings for troubleshooting or creating stereo effects.

Applies various record equalizations for LPs and 78s, or turns off for digital sources.

Load factory presets or save custom user settings, including MM, MC, CD, and PC configurations.

Monitor signal levels using dBFS values. Understand peak and average signal ranges for optimal performance.

Details the signal flow from input through gain, ADC, DSP, and DAC to the output stage.

Guidance on reducing gain or volume if +00dBFS peak signals occur at ADC or DAC stages.

Explanation of switching between Average and Peak signal modes using the Select button.

Works with all record players and cartridges, with gain settings from -4dB to 72dB.

Max input/output 2Vrms. Selectable input impedance: 47k ohms or 200 ohms for moving coils.

Lists analog gain stage (NJM2122M), ADC (PCM1808), DAC (PCM5102A), and DSP (ARM Cortex M4).

Digital conversion performed at 24-bit resolution with a 96kHz sampling rate.
