Technics SU-A900 MK2 and AC Technics EX7 imdpedance problem

[ilyuhas]

Good evening!
Technical question! I have a AMP Technics SU-A900 MK2 and AC Technics EX7 with an impedance of 4 ohms. AC has 4 connection connector on HF and LF. I connect HF to the group A on amplifier, and HF to the group B. Group A of AMP supports the connection of a 4-ohm. Group B only 8 ohms. In conjunction same group A+B 8-16 ohms. How does it affect the amplifier? Can it break down? How do better?

Looking at the specs below it seems the amp will do just fine. These older amp builds are quite robust. But do check out with other FM's before you crank it up.

Power output: 90 watts per channel into 8? (stereo)

Frequency response: 20Hz to 20kHz

Total harmonic distortion: 0.01%

Damping factor: 60

Input sensitivity: 0.17mV (MC), 2.5mV (MM), 150mV (line)

Signal to noise ratio: 64dB (MC), 78dB (MM), 91dB (line)

Channel separation: 50dB (line)

Output: 150mV (line)

Speaker load impedance: 4? to 16?
