How to increase volume of my turntable - pre-amp - amp setup
Thanks for your help folks. I think I understand that if I get a a phono preamp unit that is compatible with the type of magnetic cartridge in the turntable then all preamps will increase the signal to the same line level. Or at least any slight line level differences would be difficult for the casual listener to notice. So a different preamp might improve signal quality but not increase its level. So it seems that what I need is something like this; https://www.amazon.com/TC-780LC-Stereo-Booster-BLACK-VERSION/dp/B000RZXAHI This component will boost the signal from the preamp on its way to the Logitech speaker system. Other people use it for this purpose. To me it would make sense for some company to combine the function of this box and a phono preamp into one unit. Maybe someone manufactures a component like this but i haven't found it yet. Am I thinking about this in the right way or am I off the mark? |
Good Day Folks! Thanks for helping me out. reubent, The Behringer preamp in my system is a phono preamp. https://www.amazon.com/Behringer-MICROPHONO-PP400-Ultra-Compact-Preamp/dp/B0028QCYS0/ref=sr_1_8?s=el... It performs well enough for my casual needs and increases the signal enough that when listening to a LP at full volume you need to talk louder when in conversation. But a CD is much louder at full volume than a LP . You have to shout. I want more volume from my LPs. czarivey you wrote: pick up phonostage with higher gain.I wholeheartedly agree! How do I know which phono preamps have higher gain? How do you evaluate specifications? When I check out preamps I see these kind of specs: Input Sensitivity: 3mV at 50K Ohms Output: 2V max (P-P) at 10K Ohms - Input Sensitivity/Impedance/PHONO 3 mV / 50K Ohms I have no idea how to use this information. Help! noromance, you suggested a different preamp. I have looked at many of these but, as I wrote above, don't know how to evaluate. I assume a pricier preamp is higher quality but does higher quality mean more gain? Search here for a choice at various price points. If I can't get a more powerful preamp this component https://www.amazon.com/TC-780LC-Stereo-Booster-BLACK-VERSION/dp/B000RZXAHI seems to be an alternative. But, as lowrider57 said I'd rather not introduce another component into the chain. Am I on the right track? |
Sorry to neglect this topic fora few days. I'm co-ordinating a renovation of my house. that kept me busy for a while. mesch, This is the cartridge i have. https://www.amazon.com/Technica-AT3600-Standard-Magnetic-Cartridge/dp/B000A3945Y/ref=sr_1_2?s=electr... 4.2mV output |
noromance, This preamp will boost the signal more than the Behringer I’m using now? I see that gain is 40dB for a mm cartridge versus 35 dB for my Behringer PP400. Here are the specs; Technical specifications Pro-Ject Record Box E Input capacitance/input impedance MC: 100ohms/120pF (low output MC) MM: 47kohms/120pF (MM or high output MC) Gain, MM / MC 40dB / 60dB Output voltage typically 300mV/1kHz at 3mV/1kHz (MM) or 0,3mV/1kHz (MC) Max. output 9,5V (1kHz) Noise floor MM / MC 94dB (A weighted) / 75dB (A weighted) THD MM / MC <0,01% / <0,05% RIAA-equalisation curve accuracy 20Hz - 20kHz / max. 0,5dB A/D converter Burr Brown PCM2904 16-Bit Delta Sigma Sampling rates 32, 44,1 and 48kHz USB output 5 pin mini b connector (USB cable supplied) USB signal digital serial data protocol USB 1.1 Input / Line output 1 pair RCA/Cinch sockets each Outboard power supply 18V/500mA DC, suitable for your country’s mains supply Power consumption 100mA DC Dimensions W x H x D (D with sockets) 120 x 32 x 100 (115) mm Weight 250g without power supply https://www.amazon.com/Pro-Ject-Phono-Box-Preamplifier-Black/dp/B01CZW87HS/ref=sr_1_12?s=electronics... |
reubent, I have the Logitech Z-680. Here is a link to the specs: https://www.cnet.com/products/logitech-z-680/specs/ I'll check those inputs. |
