I have just bought a Pro-Ject Debut Carbon DC with an Ortofon 2M Red cartridge. I plan to buy a new amp and speakers later. Up until now, I've run my previous turntable through the auxiliary input on my receiver (Grundig R 120 from sometime in the nineties), and it's worked well enough, though with some limitations sound-wise.
In the manual for my new turntable, it says if not using a preamp, I should only connect it to a receiver with a phono input, which
offers correct matching and amplification for the used cartridge. Line inputs (such as CD, Tuner, Tape or Video) are not suitable.
What are the consequences of connecting the turntable to Aux, and is there any risk of damaging any part of the equipment (receiver, speakers or turntable)?
As a note, here are the relevant (to the best of my little knowledge) technical specifications for the cartridge:
Channel separation: 22 dB / 1 kHz
Output voltage: 5.5 mV
Recommended load impetance: 47 kΩ / amplifier connection – MM-input
Technical specifications for the receiver:
Load impedance: 47 kΩ
Music output: 4Ω, 2 x 45 W
Speaker impedance 4–16Ω
Input sensitivity/impedance: 180 mV / 47 kΩ
The receiver appears to have ground on an input labeled AM/loop
Also, I don't know what half of this means.
