Please kindly refer to the instruction manual and product details page for specific connection methods. thanks for your understanding.also you can send email to XIAOKOA service team: support@xiaokoa.com

I need 6 of these. How many frequencies/channels are there and how do you adjust the channel on the transmitter and the receiver?

hi,the frequency is 550-595MHz, After the microphone and receiver is connect successfully, long press“-"button on transmitter switch to frequency conversion mode.The number at the beginning of the display "C" represents the channel mode (such as C06). Short press*+/-"key to change frequency,the number at the beginning of“U" indicates volume mode (such as U08). more details can check the user manual. and any problem welcome to contact our customer service: support@xiaokoa.com

How do I order a small receiver replacement.

As far as I know they do not sell the receiver separately. That's a shame because that is the part that breaks easily. You have to buy another complete set. Hoping the manufacturer reads this and changes the design. Fat chance?

Is there a certain frequency to use with tenor sax

No the frequency are for the transmission of the signal. What affects the pick up of the sound is the dynamic range of the microphone.
