Installation - AKG AS8 Operating Instructions Manual

I
NSTALLATION
Installing the AS8 properly is simple, and only requires attention to a few issues. The AS8 should be used in a grounded
metal rack. If only one AS8 is being used, it should be placed in the Master mode, using the rear panel switch. Erratic
performance will result if the unit is in the Slave mode, but no damage will be done to the unit. Proper operation will be
restored when the unit is switched to the Master mode. If multiple AS8s are used together, the first AS8 (i.e. the one with
Expansion In port used but not the Expansion Out port) should be switched to the Master mode, while all other AS8s should
be in the Slave mode. Figure 2 shows the correct interconnection for multiple AS8s.
Microphone connections should be made with good quality braid or foil shielded twisted pair. The shield should be used for
the ground (Pin 1) connection. If an unbalanced signal is used, the unbalanced signal lead should be connected to the "+"
input terminal, while the unbalanced ground lead should be connected to both the "-" and ground terminals of the input
connector.
Output connections to the Main Out connector can be made balanced or unbalanced. If an unbalanced connection is
desired, simply connect the unbalanced signal lead to the "+" output terminal, and the unbalanced ground lead to the
output ground terminal. Leave the "-" output terminal unconnected.
Access to the Remote Level Control port is accomplished using the DB-15 connector (supplied).
