Hello all Can I connect speakers with an impedance of 4 ohms to this AVR receiver? I read something in the specifications about 6 and 8 ohms. If I remember correctly, the speakers must not have less than 6 ohms in this case. Is this correct? I have read a report that has left me unsure: "The AVR-X4500H has an advanced power amplifier unit with all 9 channels configured identically. Discrete high-current power transistors are used. All channels are rated at 200 watts each and speakers with an impedance of 4 ohms can be safely driven through all channels." Thanks in advance for your feedback and help
