Want to make sure I have the correct settings for my phono pre-amp


Hello,

So I have a Jolida JD9 II phono pre-amp.

I have a Hana SL MC Cart. This Cartridge calls out for >400ohms for the impedance.

I have the following settings set on the Jolida:

- 1000ohm for the impedance

- Using the High Output for the interconnect (since the Cart is low output and according to the instructions). The manual states to use these outputs for Integrateds and line stage pre-amps

- For the Voltage Gain dip switches: set to MC Low

The Impedance setting of 1000ohms, I know I can try different settings but for the other settings, I believe that is what I am supposed to use according to the instructions but wanted to see if anyone else has used this phono pre-amp or have any opinions.

Using the high outputs definitely sets the gain really high as on my Integrated, I turn up the volume just a couple of notches and the music is already pretty loud.

Thnx

According to specs:

Phono Stage:

            MM:                            60 dB, 5 mV 

            MC High:                    75 dB, 0.5 mV – 1.5 mV

            MC Low:                    85 dB, 0.25 mV – 0.5 mV

If 60,75 and 85 dB are gain value, set it to MC High 75 dB gain will give you better control of volume level.

 

It seems you've been wrestling with this since March 2021?

These specs seem a bit odd to me.  60dB gain is usually for a MC cart with output around 0.5mV.  36-42db is more consistent with MM gain.  I've never seen MM gain that high before.  Accordingly the MC High and Low gain on this phono all seem really high.  Clearly I'm missing something here or this phono is meant to be paired with a really low gain amp?

According to the manual, it states the Low Outputs are for use with Pre-Amp Separates and it is 200 Milivolt.

I guess I can try it, shouldn't hurt anything

Agree, you can try High output or Low output with any Gain setting to achieve best control of volume level with highest signal to noise ratio possible.

Good point. The weakest cart I own is .26 mV.

65 dB is perfect.
