Discussion in 'Audio Hardware' started by Mrtn77, Dec 16, 2020. Thanks for the suggestion. Looked at a picture of the back of your model and i would think you set it to high. lacks a high-pass section for its midrange speaker, so at low frequencies those Sounds very clean and amazing as well. transducers that operate with AC signal input. The output audio source setting on the connected component is not PCM. Switching this to 4 ohm mode limits power supply voltage and output power. One can change it between 4-8 or 6-12 ohms, depending on the brand. musical information lies. 1 CD input jacksUsed to connect a CD player (see page 9).2 PHONO jacks and GND terminalUsed to connect a turntable that uses an MM cartridge, and to ground the terminal (see page 9).3 Audio input/output jacksUsed to connect external components, such as a tuner, etc (see page 9).4 DIGITAL (OPTICAL) jackUsed to connect a component with a digital optical output (see page 9).5 DIGITAL (COAXIAL) jackUsed to connect a component with a digital coaxial output (see page 9).

What if I bi wire to my Klipsch RF7 Mark iii what should I switch it to high or low, this is so confusing for me, because on the front of the amp it has an a or b or a + b option and I'm using the a + b option, right now I have it set in low.. any help would be appreciated thank you. Its not set for 6 ohm, if you read the text High is minimum 6 ohm. Extremely pure sound quality and outstanding drive power. Use a turntable equipped with an MM cartridge. We recommend leaving it at the default 8 ohm setting and NEVER changing it. 93.5 sensitive is great. Set the corresponding SPEAKERS selector to A, B or A+B BI-WIRING position. Connect the audio plugs firmly. They also could have opted to add a larger cooling mass, but that's a question of price.
