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 [email protected] 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.







Switch Settings

No. of 8 ohm pairs

Figure 2 Impedance Chart

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 amplifier 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 amplifier’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 3⁄8” 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

Amplifier 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)
