2db's over the stated "optimal" range is likely negligible.
You'll maybe experience a click or two more sensitivity on the volume knob?
I wouldn't stress over it.
Phono Amp Spec’s
Hello
Can someone please help me understand the following…
*Maximum Input Voltage
64dB = 5.7mV
70dB = 2.9mV
34dB = 180mV
40dB = 90mV
I would be using a Benz Micro Ruby ZH moving coil cartridge with this phono amp.
It’s output is rated at .7mV@3.54cm/sec which I believes equates to .998mV @ 5cm/sec.
1. Am I understanding this correctly, that my roughly 1mV cartridge would be fine going into this 64dB MC input?
2. Is there a way to know what would the dB overload margin would be with 1mV @1khz as well as the low, mid, and high frequencies going into this 64dB MC input?
Secondly,
I’m concerned about over driving/clipping the phono amp.
* Input sensitivity
64dB = 1.26mV
70dB = .63mV
34dB = 40mV
40dB = 20mV
1. Can you please help me understand how the input sensitivity of 1.26mV for the 64dB MC input relates to my Benz Ruby ZH with a roughly 1mV output.
What exactly should this mean to me?
After suffering 5 major strokes, my memory of many things have been lost. So, if anyone could please help me better understand how the above spec’s would affect me, I would truly appreciate it.
Best wishes,
Don

From the Benz Micro site: "The ZH at .7mV, is ideal for tube phono stages in the 50-60dB gain range.' https://benzmicro-northamerica.com/benz-micro-ruby/ Determining what sounds right to your ears won't damage anything. 64db choice isn't far out of suggested range.
