Introducing the Headphone Director
Congratulations on selecting the LDG Headphone Director, a simple solution to an odd problem. Most
computers have their audio connections on the back or side where they’re not easy to reach. The
Headphone Director moves the audio output jack to the front of the computer where it belongs, and
automatically disconnects the external speakers when headphones are connected. The Headphone Director
is compatible with most personal computers, both Macs and PCs. The Headphone Director is a passive
device requiring no external power, and installation is simply plug-and-play.

Welcome Notes
Welcome to the LDG Electronics family of amateur radio equipment! Starting in 1995 and based in St. Leonard, Maryland, LDG
defines state of the art equipment for the Amateur (“Ham”) radio community.
In addition to offering established equipment we’re continuing to grow our product line. Check our web site
(https://www.ldgelectronics.com) often to learn about new developments! We also offer complete product support through our
web site, and we’re here for you for any questions that you might have. All of our products are supported with a two-year
transferrable warranty. When you sell your LDG product provide the new owner with a copy of the original sales receipt and the
two-year warranty transfers to the new owner.
There is no need to complete a warranty card or to register our products. Your product receipt establishes eligibility for warranty
service; save that receipt! Send your receipt copy with the product when you ship your product to us for repair. Products sent to
LDG without a receipt are considered requests for out-of-warranty repair.
LDG does not warranty against product damage or abuse. This means that a product failure, as determined by LDG, to be caused
by the customer or by other natural calamity (e.g. lightning) is not covered under the two-year warranty. Damage can be caused
by failure to heed the product’s published limitations and specifications or by not following good Amateur practice.
OUT OF WARRANTY SERVICE
We will gladly provide service any time a product fails after the warranty. Send the product to us for repair. We will determine
what needs to be done, and, based on your prior instruction, either contact you with an estimate or fix it and contact you with a
request to pay any repair charges. Please contact LDG with any questions before you send us an out-of-warranty product for
repair.
RETURNING YOUR PRODUCT FOR SERVICE
Returning a product to LDG is easy. We do not require a return merchandise authorization, and there is no need to contact LDG
to return your product. Visit the Customer Support Center on our web site and download the LDG Product Repair Form. On the
Repair Form tell us exactly what happened (or didn’t happen) and why you believe the product needs servicing. The technician
will attempt to duplicate the problem(s) you had based on how well you describe it so please be accurate and complete.
Ask your shipper for a tracking number or delivery verification. Please include your email address so our shipper can alert you
when your product is being returned to you. Be assured that our staff makes every effort to complete repairs ahead of our
published wait time. Your patience is appreciated.
Repairs can take four to eight weeks, but are usually faster. The most recent information is found at the LDG Customer Support
Center. Send your carefully packaged unit with the Repair Form to:
LDG Electronics, Inc.
Attn: Repair Department
1445 Parran Rd
St. Leonard, MD 20685
PRODUCT FEEDBACK
We encourage product feedback! Tell us what you think of your LDG product. In a card, letter, or email (preferred) tell us
how you use the product and how well it worked in your application. Send along a photo or even a schematic or drawing to
illustrate your narrative. We like to share your comments with our staff, our dealers, and even other customers at the LDG

Installing the Headphone Director
The Headphone Director is intended for indoor use only; it is not water-resistant. If you use it outdoors, you
must protect it from rain.
Always turn your computer off before plugging or unplugging anything; it may be damaged if cables are
connected or disconnected while the power is on.
With the computer turned off, unplug the external speakers. Connect one end of the supplied stereo cable
to the computer’s audio output jack; it may be labeled “Line Out”, “Speakers” or “Headphones” on some
computers. Connect the other end of the cable to the jack marked “Computer” on the back of the Headphone
Director. Plug the external speakers into the jack marked “Speakers” on the back of the Headphone Director.

Operation
Simply plug your headphones into the Headphones jack on the front of the Headphone Director. The external
speakers will be muted, and the audio routed to the headphones. To return to listening on speakers simply
unplug the headphones. You should reduce the volume level before plugging in headphones, as speaker-level
audio might be uncomfortable in headphones.
Application Notes
If desired you can attach the Headphone Director to the front or side of your computer, or any other
convenient smooth surface, with the adhesive pad attached to the unit’s back. Simply peel off the release
paper and press the unit onto your desired location.
Care and Maintenance
Your Headphone Director is essentially maintenance-free. The outer case may be cleaned as needed with a
soft cloth slightly dampened with household cleaning solution. As with any modern electronic device the
Headphone Director can be damaged by temperature extremes, water, impact, or static discharge.
