There are 2 options available for rack mounting the U-800 receiver: singly or side 

by-side with another U-800 receiver.

  a.  Single mounting: Remove the receiver SIDE MOUNT CLIP (24) from each side of 

the receiver (as shown) and slide in the optional ERM-12 RACK EARS (25).

  b.  Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (24) from 

both U-800 receivers join the two receivers with the EJC-3 JOINING CLIP (26) 

and attach the ERM-22 RACK EARS (27) as shown. 

(Note: Do not mount the receiver in a rack directly above an amplifier or other source 

of high heat — this could degrade the performance of the U-800. Always ensure 

adequate airflow and heat dissipation in any rack configuration.)
