Parasource System Control
6. Sub In/Out Mode
When using a subwoofer the Sub In/Out LF rolloff switch disables the low frequency boost and filters out
signals below 100 Hz. It’s not necessary to use this switch for speech applications because the Mic input
already has a high pass filter. This switch only affects the signals to the internal amplifier and does not af-
fect signals going out from the internal mixer, or signals passing through the Link connections.
7. Club/Concert Mode
The Club/Concert Mode switch allows the Parasource enclosure to be quickly configured for the
venue and/or type of source content. The Club mode enhances bass frequencies before the onset of
limiting. Once the cabinet begins to limit, this enhancement is reduced to prevent more severe limit-
ing. The Concert mode forgoes the bass boost and relaxes the horn peak limiter by 4dB, allowing for
a longer throw from the cabinet.
8. Link XLR and Input Combi Connector
The Link jacks are in parallel, enabling multiple Parasource enclosures (or any other powered cabi-
nets, like powered subwoofers) to be connected together. The Link jacks are the correct input to use
when driving the Parasource enclosure from an external mixer. The Link jacks operate at line level (+4
dBv) to achieve full power. When operating from weaker signals, it’s suggested to use the Line inputs
of the first cabinet in the chain.
Note: The Link jacks are high quality balanced inputs with very good common mode (hum)
rejection. To ensure maximum hum rejection, the proper balanced cables must be used. The
Jack marked LINK is connected in parallel with the INPUT and are provided for convenience
to connect downstream cabinets. Link inputs may also be used as outputs and link outputs
may be used as inputs.
9. Level Control
The Level control adjusts the volume of the individual Parasource enclosure and allows each cabinet,
linked in a chain, to be individually adjusted. This control does not adjust the level of the Link jacks.
System Power and Status
10. Green Power LED
The green Power LED illuminates when the AC power is on and the unit is ready.
11. Yellow Limit LED
This yellow LED indicates that the limiter(s) are actively managing the signal level and the unit is
operating at full power. It’s okay to operate while limiting as long as the red Clip LED is not constantly on.
There are separate limiters for the woofer and horn. This LED will indicate operation of either limiter. The
Limit LED does not indicate low frequency processing action.
12. Red Clip LED
The illumination of this red LED indicates that the signal level is excessive and may cause distortion. Reduce
mixer levels or turn down the level of your source to reduce clipping.
13. Power Switch
The power switch turns the power On and Off for the enclosure.
14. Circuit Breaker
The circuit breaker should never blow, even in extreme operating conditions. A tripped breaker will
generally mean there’s a serious fault with the unit. If the circuit breaker trips repeatedly, bring the unit to
a qualified Yorkville technician to have your cabinet serviced.
