Installation Instructions
Warranty & Repair
All OSD Audio speaker products have (5) year Limited Warranty against defects in materials and
workmanship. Proof of purchase must accompany all claims. During the warranty period OSD
will replace any defective part and correct any defect in workmanship without charge for either
parts or labor.
OSD Audio may replace returned speakers with a product of equal value and performance. In such
cases, some modifications to the mounting may be necessary and are not OSD’s responsibility.
For this warranty to apply, the unit must be installed and used according to its written instructions.
If necessary, repairs must be performed by OSD. The unit must be returned to OSD at the owner's
expense and with prior written permission. Accidental damage and shipping damage are not
considered defects, nor is damaged resulting from abuse or from servicing performed by an
agency or person not specifically authorized in writing by OSD.
OSD Audio sells products only through authorized dealers and distributors to ensure that custom-
ers obtain proper support and service. Any OSD product purchased from an unauthorized dealer
or other source, including retailers, mail over dealers and online sellers will not be honored or
serviced under existing OSD warranty policy. Any sale of product by an unauthorized source or
other manner not authorized by OSD shall void the warranty on the applicable product.
Damage to or destruction of components due to application of excessive power voids the warranty on
those parts. In these cases, repairs will be made on the basis of the retail value of the parts and labor. To
return for repairs, you must email customer service at [e-mail] for a Returned Merchandise
Authorization (RMA) number# then the unit must be shipped to OSD at the owner's expense, along with
a note explaining the nature of service required. Be sure to pack the speaker(s) in a corrugated container
with at least 3 inches of resilient material to protect the unit from damage in transit.
This Warranty Does Not Cover:
Damage caused by abuse, accident, misuse, negligence, or improper operation (installation) • Any
products that have been altered or modified • Any product whose identifying number of decal,
serial #, etc. has been altered, defaced or removed • Normal wear and maintenance.

OSD Audio does not recommend installing more than 8 volume controls in parallel. OSD
audio also does not recommend installing more than two 8 Ohm speakers per channel
on each volume control without additional impedance protection.
Setting the impedance match switch higher than 1X yield less power per pair of speakers.
For example: an amplier rated at 80 Watts per channel RMS into 8 ohms is to be used for 8
pairs of speakers. In order to accommodate 8 pair of 8 ohms speakers, an 8 impedance
match setting must be used, therefore, this will limit to power to 10 watts for each speaker
pair, or 1/8th of the amplier’s power. (See Fig. 2)
Step 2: Mounting the enclosure
- If conduit is to be used, run the necessary wiring up
through the conduit and into the opening at the base of
the enclosure.
- Mount the enclosure onto the PVC conduit using the
applicable adhesive material
- Use the 4 holes in the back sides of the unit to secure
the enclosure to a stationary object or wall. (See Fig. 3.)

Step 4: Install volume control in the enclosure
Step 1: Determine and set impedance with match switch
- Count the total number of 8 ohm and 4 ohm speakers you are connecting to.
- Determine if the amplifier can support an 8 ohm or 4 ohm speaker load. You should be
able to find the information in your amplifier or receivers owner’s manual.
- Determine the correct impedance match switch setting using the chart below
(See Fig. 2)
- Set the impedance match jumper on all the volume controls in the system to the same
position (1/2X, 4X, or 8X). (See Fig. 1.)
Strip ¼” to ⁄” of the insulation from your connection
cables. Twist your input wires with the OVC 300 input
wires. Apply the same procedure for the output wires.
Make sure all the cables are consistent in polarity. (See
Fig. 4)
Once connected, run the output cables from the
Amplier to the Volume Control’s input wires.
Followed by running the cables from the Volume
Control’s output to the speakers input terminals. (See
Fig. 5)

2) Place the cover plate
over the enclosure. Make
sure the plastic rubber
