2-channel Broadcast Announcement Connection
• For 2-channel broadcast announcement, connect the WA-BA240N as shown below.
Important
• Use the gold plated plug (accessories of WA-BA240N) when connecting to LINE IN of WA-BA240N.
• Set the 2-channel announcement volume using the LEVEL knob of WA-BA240N.
Important:
If you want the WA-BA240N to turn on together with the WA-MA120N or WA-MA240N, connect the OPERATE LINK terminal to the OPERATE
ON terminal of the WA-BA240N.
Note:
If other amplifiers except WA-BA240N are required, select appropriate power amplifier rated output in accordance with ZONE1 speaker
impedance.
