- Page 2 PuYn Quick Start Connect the music source, like a turntable or CD player, to the PuYn's input. Then connect the PuYn's output to your main stereo device, like an integrated amp or ac ve speakers. The PuYn has three controls: the Standby bu on, the Knob, and the Select (arrow) bu on.
- Page 3 1. Volume Typically the Volume will be le at 100% and a system master volume control will be used elsewhere. But it can be used as a cue mute when changing records and cleaning the stylus. Select and rotate the knob CW (clockwise) one click for Mute. Rota ng CCW (counterclockwise) will a enuate the signal and lets the PuYn be used with systems lacking a volume control.
- Page 4 4. Treble This is a treble shelving control with a corner frequency of 3kHz. It adjusts in 1dB steps. CCW [less treble]: -6,-5,-4,-3,-2,-1,+0,+1,+2,+3,+4,+5,+6 :[more treble] CW 5. Air Air is a higher frequency treble control (above 8kHz) that is intended as a cartridge loading adjustment.
- Page 5 7. Lo (Low Frequency Filter) This is a 4th order Bu erworth ®lter to a enuate lower frequencies. While mainly it is used to eliminate vinyl rumble and tonearm resonances, it can be adjusted higher for use with old LPs and 78s. It can also be adjusted to 68Hz or higher to reduce mains hum which may be present on many older recordings.
- Page 6 10. Gain Get your sound source well matched to your stereo system with the PuYn’s wide range of gain se ngs: from -4dB for high level inputs (CDs, DACs) to 72dB gain (low output moving coils). 40dB is a typical gain se ng for most phono setups. Remember to always turn down the main system volume when adjus ng the gain to prevent loud surprises.
- Page 7 12. Balance This provides balance control between the le and right channel in 2dB steps. CCW: L15,L14,L13,L12,L11,L10,L09,L08,L07,L06,L05,L04,L03,L02,L01,+00, R01,R02,R03,R04,R05,R06,R07,R08,R09,R10,R11,R12,R13,R14,R15 :CW 13. Fine Balance Adjusts the le channel in +/- 0.3dB steps to match the right channel. This can be done by monitoring the average signal levels. Using a mono record in Mode:Stereo you can see the diVerence in levels at the le &...
- Page 8 15. EQ These are diVerent record equaliza ons that have been used over the last seventy years for 78s and LPs. It will be turned oV for non-vinyl sources like CDs or digital mu- sic. For most vinyl users, the 'RIAA LP' will be the only se ng ever used. For enthusi- asts with older LPs and 78s, the other EQ se ngs will provide a proper equaliza on for best sound from these records.
- Page 9 Signal Levels The Pu n signal levels can be monitored between Set? and olume. These show a dB full scale (dBFS) value, so +00dBFs is the max signal the Pu n can handle at that stage in the Pu n, and this is normally a nega ve value. The more nega ve, the smaller it is. The Pu n routes the signal in the follow way: Input ->...
- Page 10 Speci®ca ons Works with all record players and cartridges. Suitable gain se ngs (-4dB to 72dB) for moving coil carts (0.25mV), HOMCs (2mV), standard MM (4mV), all the way to CDs and DACs (2V). Max input and output: 2Vrms Input impedance: 47k ohms (50pF) selectable to 200 ohms (1nF) for moving coils Output impedance: 1k loads and up, but will drive some sensi ve headphones Analog gain stage: NJM2122M ADC: Texas Instruments PCM1808...
