65.93.17.241
I'm considering the purchase of a used ATC SCA-2 preamplifier (made in 2007) to drive a pair of powered monitors (Meyer Sound Labs X-10T).
I've checked the specifications of the SCA-2, but nowhere do I find mentioned the gain of the preamp, just the voltage output (15 or 17.5 Vrms, depending which spec sheet).
However, I need a minimum of 12 dB gain (14 or 16 dB better), and, so far, I have not received any response to my enquiries from ATC in the UK.
So. . .if anyone has this information and could let me know, I'd be most grateful. Thanks!

I think you'll be fine with 12.77 espevially with the ten ohm output impedance. We were ATC dealers and I liked it too by the way.

Did you check the user manual, might be here:

I just posted the link to the manual in my post below. The specifications are on page 11. The manual specifies sensitivity to be 230-mV for a 1-volt output. That equates to a gain of 12.77-dB.
Good work John!
John,
Many thanks for providing the translation to dB of gain!
Much appreciated!
Regards, Joel.
Hi Joel,
The gain would be 1 / 0.23 = 4.348
The decibel conversion would be 20Log(4.348) = 12.77-dB
Best regards,
John Elison
I found a manual with the following spec sheet. It claims a sensitivity of 230-mV for 1-volt output. That equates to 12.77-dB gain.
