JBL SB210 - Manual (Page 5)

Important Satellite Connection Information
For Mono (& 70V Mono) Systems
For Mono systems, always connect half the satellite speakers to one of the satellite speaker output terminals and the other half to the
other satellite speaker output terminals.
Do NOT connect to only one of the sets of satellite output terminals .
In order to avoid excessively low impedance loads to the power amp when using 4 satellite speakers (which could cause the power
amplifier to fail), the satellite output terminals of the SB-210 in mono mode are connected in series with each other. This requires
that speakers be connected to both sets of satellite output terminals, and that the load on each satellite output be matched.
Otherwise, there will be very little or no sound coming from the satellite speakers
