WARNING! (note to structural engineer)
NOTE: Use the correct type and grade of bolt into the mounting point inserts. The correct mounting bolt
diameter and thread spacing are: M8, 1.25 mm per thread. Use of a metric grade 8.8 bolt or better is recom-
mended.
The SP®118P Sub mounting inserts are designed to be used in groups of three with the proper forged machinery
eyebolts used
Hardware for Flying/Rigging the SP®118P Sub
Eyebolts or bracket bolts should be M8 metric thread, 1.25 mm per thread.
Eyebolts and bracket bolts must conform to certain minimum strength criteria for safety reasons.
Unspecified eyebolts found at local hardware stores are not strong enough to maintain safety for overhead flying
or rigging. Use only forged steel shoulder machinery eyebolts designed for rigging use, which adhere to the stat-
ed standards as outlined below.
Hardware Specifications
Forged shoulder machinery eyebolts should be an M8 size, 1.25 mm per thread, and must conform to DIN 580
or ASTM A489, for Germany, BGV-C1 is the relevant standard. Minimum shank length should be 20 mm. The
eyebolts should be rated for a minimum of 450 lbs straight pull working load
Bolts used on custom mounting brackets must be certified to be a metric grade 8.8 or better.
If there are any questions regarding the proper hardware or practices for safe flying or rigging of the Peavey
SP®118P Sub, contact a certified structural engineer, or consult with those local rigging companies who have
trained and certified personnel.
Operation
Connecting a Signal to the SP® 118P Sub
There are a variety of ways to input a signal to the SP® 118P Sub.
The inputs (5) provides either a balanced mic- or line-level input, allowing the use of a 1/4" TRS (ring-tip-sleeve)
type phone plug or a male XLR plug.
There is also a 3.5 mm MEDIA IN jack on the Channel 2 input.
The 3.5mm TRS input jack has its own preamp designed for connection to the headphone jack on mobile audio
devices. The Channel 2 Gain control adjusts the signal level from all of the channel 2 input connectors. It is pos-
sible to use both the combo mic or line input and the 3.5mm input by setting the channel 2 Gain control for the
combo input source, and then using the mobile devices headphone volume to adjust its volume.
Note that the 3.5 mm jack mixes a stereo signal down to monophonic, as the SP® 118P Sub is a single sound
source.
Do not connect cables to the jacks while the unit is ON and the Gain knob is turned up! While a standard
single-ended 1/4" phone plug-equipped cable will work well and the balanced input circuitry will provide some
interference rejection, a balanced cable using either the balanced TRS 1/4" phone plug or the XLR plug will pro-
vide superior interference rejection and performance.
Sometimes, with difficult interference problems, it will be helpful to lift the shield ground ( Pin #1 of an XLR) of
a balanced cable at the SP® 118P Sub end. Check any input changes carefully, always turning the Gain control
down before plugging and unplugging cables, or lifting the ground.
