1. Power Switch and Indicator
The green power LED illuminates when
the power switch is turned to the On posi-
tion and AC voltage is supplied. When the
power is removed or the power switched
is moved to the off position the green power indicator will blink while
the power supply is discharging. The processing circuitry will not reboot
unless the power supply is fully discharged before being turned back on.
It is not necessary to reboot however. Turning the power back on before
the power supply is discharged will simply resume normal operation.
2. PowerCON TRUE AC Loop Thru
As a standard, the AC inlet on the SA115S accepts locking PowerCON
TRUE power cords. There is also an AC outlet that can be used to loop
power through to other cabinets in your array using a male to female
PowerCON TRUE looping power cord. Check with your local Yorkville
dealer for availability of these accessory cords.
IMPORTANT: DO NOT EXCEED THE CURRENT
RATING OF THE POWER and ACCESSORY CORDS.
PLEASE READ THE SECTION OF THIS MANUAL
CALLED “CASCADE INSTALLATION.”
3. Input Jack
This female-XLR accepts line level XLR microphone cables. For best
noise reduction use balanced sources.
4. Dual Link Outputs
These XLR male connectors can be used with a standard XLR cable to
daisy-chain up to 20 SA115S or SA315 cabinets without signal degrada-
tion. Simply loop from one cabinet’s Link jack to the next cabinets Input
jack. In many cases this limit of 20 cabinets can be exceeded, consult
Yorkville Sound for more details.
5. SA115S Level Control
This control adjusts the volume level of the SA115S relative to the input
signal level. Mixers and other audio sources connected to the SA115S
tend to have different output voltages, which mean the level control
on the SA115S is used to fine tune the cabinet’s volume relative to the
mixer settings. It is perfectly acceptable to set the SA115S Level above
or below the center 0 dB setting.
6. Clip, X-Max, VC-Therm,
Activity Indicators
The Clip and Limit LED indicators illuminate
to guide the user to proper operating levels.
Illumination either of the yellow Limit
LEDs indicates that a level has been reached where the SA115S limiters
are reducing the signal internally to prevent damage or distortion. It also
indicates that further increases in input level or increasing the SA115S
Level control position will not appreciably increase acoustic output.
The red Clip LED indicates that the input level is excessive and further
increases in level will cause severe distortion The input signal should be
reduced at the source until Clip activity ceases. The clip indicator comes
on at 12 Vrms,16 volts peak. The input clips at 17 Vrms, 24 volts peak.
The activity Indicator comes on at 5 mVrms or -45 dBV.
7. Line Current Limit Control
The Line Current Limit control allows the power to be reduced to allow
operation on limited power availability. Full power transients will be
allowed through but if the average power is excessive then the power
will be limited. This control works by advancing the limiter that limits the
voice coil temperature and by monitoring the current draw. In the 5 amp
position the average power is limited only by the voice coil temperature.
In the 4 amp position with most music, the limiter will be only active oc-
casionally depending on the music content. In the 3 amp position certain
types of music will not be limited, primarily music without deep bass or
where the bass is vunprocessed. The 2 amp position will significantly
reduce the output when the music content has continuous bass content
below 45 Hz. The green power on indicator will dim to indicate when
the line current limiter is active. A small amount of dimming indicates
thavt the advanced thermal limiter is active while significant dimming
indicates that the line current monitoring system has detected excessive
line current. Low line voltage typically due to long power supply cables
may cause excessive line current, the line current monitoring system will
prevent this from tripping the power source circuit breakers.
