2.3 Ensuring Proper Cooling
When using an equipment rack, keep a minimum space of 4 inches (10cm) from the
top surface of the unit. Close any open spaces in the rack with blank panels. DO
NOT block any air vents. The side walls of the rack should be a minimum of 2 inches
(5 cm) from the amplier sides. The back of the rack should be open.
2.4 Choosing Input Wire and Connectors
We recommend using prebuilt or professionally wired balanced line (two-conductor
plus shield) 22-24 gauge cables to connect the amplier balanced input by using the
included Euro-block connectors, see Figure 2.4. Unbalanced lines may be used, but
may result in hum or RF noise very long cable runs.
You can also use RCA connectors to connect audio devices, for example, CD/DVD
player. However, do not use both Euro-block and RCA audio input connectors on a
single channel at the same time.
NOTE: Custom wiring should only be performed by qualied personnel.

use both Euro-block and RCA connectors concurrently for any single input channel.
