115v - 230v AC Voltage Selector Switch

This switch is found on the chassis rear panel. The 115V position of this switch is correct for North America; most other regions require setting it to 230V. Make sure the 115/230V switch is set for the correct AC line (mains) voltage before you connect the Model 2125’s power cord and before you install it. The unit may be seriously damaged if this switch is set incorrectly.

Installation and Ventilation Requirements

Install your Model 2125 away from heat sources such as heating ducts, radiators, or other heat producing components. Always position it horizontally.

Observe the following ventilation guidelines when installing the Model 2125 in an equipment rack or any other enclosed space:

You should never install the Model 2125 in an unventilated equipment cabinet or compartment because hot air will not exhaust adequately to prevent overheating. Air won’t often circulate adequately in a cabinet or enclosure whose front and back sides are open; pockets of intense heat can still develop around any heat-producing equipment. Therefore, a ventilation fan is high- ly recommended. Allow a few inches of empty space on each side and above the unit and try to avoid crowding or stacking the Model 2125 tightly between other components. A ventilation fan is also recommended where other equipment must be mounted close to the Model 2125.

Do not place the unit on carpeting or any other material that could obstruct air flow into the ventilation holes in its chassis bottom.

Rack Mounting

The Model 2125 front panel occupies only two rack spaces in a standard 19 equipment rack.

For rack mounting, you’ll need to use the Parasound RMK22 rack mounting kit (purchased separately). We recommend that you use the 8 insulated shoulder washers with the four mounting bolts which are included with the RMK22. Position these washers on both sides so they “sandwich” the front panel before the mounting bolts are screwed into the rack rail. This will eliminate metal-to-metal contact between the Model 2125 chassis, the equipment rack, and the other components in the rack.
