Wired Audio Link
The CHALLENGER 1000 could be operated as MASTER as well as SLAVE. This depends on
the setting of Master/Slave selector switch. However, the CHALLENGER Slave can only be
operated as SLAVE.
In order to operate Audio Link, you must have a CHALLENGER 1000 unit that operates as a
MASTER. Only one unit is allowed to act as MASTER and the other(s) MUST operate as
SLAVE(s). A MASTER unit is capable of connecting up to about 20 SLAVE units.
For the MASTER unit, the MASTER/SLAVE selector switch must be set to MASTER mode.
The CHALLENGER SLAVE unit does not have this selector. If you have two units of
CHALLENGER 1000, you could use one as Master and the other CHALLENGER 1000 as
slave. To do that, just put the MASTER/SLAVE selector switch of the second CHALLENGER
1000 to SLAVE mode. For the MASTER unit, Audio Link IN jack should NOT be connected.
To operate Audio Link, connect the Output jack of the MASTER to the Audio Link IN jack of the
1st SLAVE unit. The Output jack of this SLAVE should be connected to the Input jack of the
2nd SLAVE unit. Similar connection shall continue as such for the following SLAVE units.
Volume Control for MASTER or SLAVE
When used on the MASTER, it controls the MASTER as well as all the SLAVE units. When
used on the SLAVE unit, it only controls that particular SLAVE unit volume. Maximum number
of SLAVE units to be connected with a MASTER is about 20.
Remark: There should NOT be a connection between the last SLAVE unit output and the input
of the MASTER unit.
