WA-BA240N
Line-level Equipment Connection
• Connect external devices (e.g. pre-amplifiers) to the LINE IN jack. The following illustration is a connection example with the
Mixing Power Amplifier (WA-MA120N or WA-MA240N).
• Be sure to use the gold plated plugs (accessories) when using the LINE IN jack and/or the LINE THRU jack.
• Refer to the Operating Instructions of WA-MA120N or WA-MA240N for input and output connection in the Main System.
And refer to the next page for method of connecting loudspeakers in the Monitor System.
• Connect the LINE THRU when you want the output of the equipment connected to the LINE IN jack to be input to other
equipment as well.
Important:
The LINE THRU jack connects directly without going through the LINE IN jack's internal circuitry.
Consequently, the load from the viewpoint of the line-level equipment is the parallel composition value of the Amplifier's input impedance
(100 kΩ) and the input impedance of the equipment connected after the LINE THRU jack. Ensure that the input impedance parallel
composition value is not less than the matching load impedance of the line equipment.

Loudspeakers (42 Ω or 21 Ω)
Speaker Connection
• Use the connections shown below for connecting high-impedance or low-impedance loudspeakers.
Caution:
High-impedance and low-impedance loudspeakers cannot be connected at the same time. When using high-impedance loudspeakers, use
either 100 V or 70 V.
Important 1:
Make sure that the parallel composition impedance of the high-impedance loudspeakers does not become less than 42 Ω in the case of 100 V,
or less than 21 Ω in the case of 70 V.
Important 2:
Make sure that the parallel composition impedance of low-impedance loudspeakers does not fall below 4 Ω. Up to two 8 Ω speakers or four 16 Ω
speakers can be connected in parallel.
