What is the output impedance?

No,this is a tube preamplifier, not a tube amplifier,impedance and power is decided according to your power amplification,hope you can understand,thanks

Just purchased this unit. when i turn on the power switch the led light below it flashes red and blue. is there a problem with the unit?

Hi sir,Red and blue flashing is the status of bluetooth waiting to be connected,Blue light indicates bluetooth connection is successful ,Only display Red light is AUX status,so pls check your use status, Use the select button on the back of the preamplifier to select the function you need,Hope it can help you,and thanks for your remind,we will add this information on our description.Any problem,pls contact us,thanks.

se puede conectar tornemesa por medio del 3.5mm?

No,no se puede. Para conectar conectar un tornamesa es necesaria un preamplificador que pueda aumentar la escasa señal del giradisco. Este equipo no la tiene

I have a crown amp i want to use this with, i am looking to connect to my yamaha rx-385 via blue tooth, just not sure if this pre-amp will work.

You can use this tube preamplifier before your amp , then use the audio cable connect your audio amp,the connect step is TUBE A3 pro to your amp than to your speaker.
