Topic: ADI 2 DAC with power amplifier
Hello,
Thank you for welcoming me to your forum.
At the beginning of this week, I received my power amplifier, namely :
Brand Kinki type EX-M7
The latter is connected via RCA to my ADI 2 DAC model 2020.
The DAC is powered via its USB input by a 2 pc audio bridged and running Fedora with Roon.
The level setting is Auto level in the ADI settings, no other modes activated, DSP, tone or other.
My concern is that towards -27 db and +, the amplifier goes to safety.
Below is the technical information of the amplifier:
Parameters
Frequency Response: 0-2.5MHz (±3dB)
THDN: <0.07% (-80db)
S/N Ratio: >103db(0.01Hz- 1 MHz), >130db (A-Weighted)
Output Power: 250 W RMS(2-8 Ohms)
Max Instantaneous Power: 400w RMS (8 Ohms)
Max Output Voltage: 70VAC, 18A
Slew Rate: 200 V /us (Rise Time < 100ns)
AC Power: 110/240VAC, 50/60Hz (Factory configure).
Power Consumption: 30W Idle, 700W Max Output
Input / Output
Input Sensitivity: 1.45Vrms
Input Impedance: 51kΩ (Acceptable Range 10k-52kΩ)
Input Connector: RCA x 1, XLR x 1
Any reason between the technical specifications of the ADI and the Kinki that could cause this problem?
Which solution ?
Thank you for your help
