1. Input Jack
This female-XLR accepts line level XLR microphone cables. For best
noise reduction use balanced sources.
2. Dual Link Outputs
These XLR male connectors can be used with a standard XLR cable to
daisy-chain up to 20 SA153 or SA315 cabinets without signal degradation.
Simply loop from one cabinet’s Link jack to the next cabinets Input jack.
3. SA153 Level Control
This control adjusts the volume level of the SA153 relative to the input
signal level. Mixers and other audio sources connected to the SA153
tend to have different output voltages, which mean the level control
on the SA153 is used to fine tune the cabinet’s volume relative to the
mixer settings. It is perfectly acceptable to set the SA153 Level above or
below the center 0 dB setting. When arraying multiple cabinets, it may
be desirable to reduce the volume of some cabinets to better cover the
audience. (ex. The outer box of a cluster may be against a wall)
4. Mode Switch (Sub/No Sub)
This switch allows the user to configure the SA153 to be used with or
without a subwoofer. In “No Sub” mode, the cabinet’s internal high-pass
(low-cut) filter is set to 40 Hz. When using the SA153 with a subwoofer,
such as the SA315, depress the button to set the internal high-pass filter
to align perfectly with the subwoofer.
5. HF (High Frequency) Adjust Selector
The HF Adjust switch is used to set the relative high frequency level of
the SA153. If you are assembling multiple SA153 cabinets into an array,
you may notice an increase in bass and a lack of treble. This is due to
low frequency coupling between the cabinets of the low frequency driv -
ers. Setting this control to the number of cabinets in the array will insure
flat response from the system. As the number of cabinets increases the
high frequency output will be correspondingly increased.
The HF switch can also be used in applications where the loudspeak -
ers are situated far from the audience. The increase of treble will help
overcome the natural loss of high frequency due to traveling a greater
distance.
6. Clip and Limit Indicators
The Clip and Limit LED indicators illuminate to guide the user to proper op-
erating levels. Illumination of the yellow Limit LED indicates that a level has
been reached where the SA153 limiters are reducing the signal internally
to prevent damage or distortion. It also indicates that further increases in
input level or increasing the SA153 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. This
happens at very high input signal levels in excess of 13V peak. The input
signal should be reduced at the source until Clip activity ceases.
7. Power Switch and Indicator
The green power LED illuminates when the power switch is turned to the
On position and AC voltage is supplied.
8. PowerCON TRUE AC Loop Thru
As a standard, the AC inlet on the SA153 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.
