Hi diyhifishop. I bought an headphone amplifier case from your store a few months back and never received it. I never got any reply from your website email and the PayPal supplied email is not valid. I tried to send an email from your ebay website and didn't get a reply either.

Please send me a private email.

I can give you the PayPal transaction details. I really want to received my case that cost me 75$.

I'm sure it is just a misunderstanding, or missing shipping info.

Thanks.
S.Bergeron.

Hi,
It looks really nice, but my question is:
Is there an option on the microprocessor to set the maximum gain?
The PGA2311 is capable of 31.5db of gain and I'm sure most of us will need max gain of about or slightly above 1.

Hi,
The remote control and the stepper potentiometer can set the maximum gain.Taking into account the distortion, so the maximum gain not use to 31.5db,only 23db.
Thanks!

I understand. This is why people need volume control! ... That was not my question, though. 🙂
I wonder if you have provided an option to limit the maximum gain, say to 0db? So, with the volume control all the way up, the gain would stay 0db and not 23db.
May be you could provide your customers with the choice to order this preamp with microprocessor programmed for say 0db, +6db or +12db of maximum gain. I doubt that anyone would need +23db.

Hello Ruwe,
Thanks for your interest. This product do not provide an option to limit the maximum gain.
Rotate the stepper potentiometer, the PGA2311 won't turn on internal amplifier when lcd displays between (-96db to -0db), at this moment it's function just is a volume control.
Rotate the stepper potentiometer, the PGA2311 will start internal amplifier when lcd displays between (0db to +23db), at this moment it will be a preamplifier, adjust stepper potentiometer and you can control the gain of preamp at (0db to +23db).

Hope you can understand for my poor English.

The block diagram for the PGA2311 shows that the signal is always going through the internal op-amp, so I don't believe this is possible.
