Section 2  Installation 
2.1 Operating Environment 
Mount the 176 in a standard 19” equipment rack. Always install the bottom rack screws 
first to support the unit. Please allow room above the top ventilation holes and above the 
tubes. Additionally, there are ventilation holes on the sides to draw in cool air. Be aware 
of the heat sources in your rack to allow proper cooling. Heat will shorten the life of 
your equipment. 
Audio equipment is sensitive to magnetic fields caused by nearby power supply 
transformers. If you experience 60 Hz. hum in any of your gear, try unplugging adjacent 
gear first. 
If you purchased a matched pair with the link panel, mount the panel between the two 
units and connect the RCA cables to the Couple jack on each 176.
