Owner’s Manual
A Few Words About Stereo and Home Theater
HTD speakers are designed to accurately reproduce high fidelity music as well as dialogue and effects in movies. Most of
us are familiar with the concept of 2-channel audio, commonly known as stereo. In a home theater environment,
recording engineers have the option of recording into additional channels. Most of today’s movies are recorded in 5.1
surround sound formats, most often either Dolby Digital or DTS. When these movies are played with a digital source,
such as a DVD player, audiences at home have the opportunity to hear all of these channels if their system has been
equipped with the appropriate speakers for each channel. When these movies are played through an analog source, such
as a VCR, the 5.1 surround signal has been converted to other analog formats, most often Dolby ProLogic. Dolby
ProLogic will make use of the same 5.1 speaker channels, although the back two (surround) speakers will receive the
identical channel of information and it is not a full range signal. The subwoofer is provided the low frequencies sent to
the other channels in a Dolby ProLogic recording. By contrast, a true 5.1 digital recording includes a completely unique
channel of both low frequencies and effects (LFE). This channel is called the LFE channel and represents the .1 in a 5.1
system. In most of today’s receivers, the five full frequency channels- front right, front center, front left, rear (surround)
right, and rear (surround) left- are “powered” channels, meaning the receiver has built-in amplification for each channel.
By contrast, the LFE channel is most often not powered. And because this channel only produces the lowest frequencies,
a powered subwoofer is necessary to reproduce the LFE channel.
Hooking Up Your Speakers
HTD Level ONE Speakers include gold-plated, push-type binding posts. The gold-plated binding posts ensure an
efficient transfer of signal and power from any standard type of cable or wire connector, including bare wire. For bare
wire or pin-type connectors, press down on the post to reveal an “eye”. Simply thread the wire or pin through the eye and
release so that the binding post securely tightens around the wire or pin. Individual or paired banana plugs can be inserted
directly into the holes at the mouth of the collar with a snug fit.
When connecting the speakers, it is very important to retain the correct polarity. This means that the wire attached to the
+, red, or positive terminal on one component must be attached to the +, red, or positive terminal on the corresponding
component’s speaker output terminals. Similarly, the -, black, or negative terminals must connect to the respective -,
black, or negative terminals.
See “Hooking Up the Level ONE Powered Subwoofer” for details on connecting the subwoofer.
Speaker Placement
All three of the front speakers- left, center, right – are intended to be directional and should be placed at approximately the
same height and distance from the ideal listening spot. The center speaker is video shielded so that the magnets inside do
not interfere with picture performance. It should be placed as close to the television as possible, so that the audio appears
to come straight out of the picture. The front left and right speakers should be placed far enough from the television to
ensure that you can distinguish sounds coming from the left and right. Typically, placing the front left and right speakers
between seven and twelve feet apart is appropriate. At a minimum, the Level ONE Main Speakers should be placed at
least two feet from a picture tube as they are not video shielded. Many audio enthusiasts recommend aiming the speakers
such that the angle created by drawing a line from one speaker to the listener and back to the other speaker is a 45-degree
angle. This setting generally mimics the condition set by the mixer at the film studio.
Place the surround speakers about as close to the ideal listening spot as you placed the front left and right speakers, and
about the same height or higher. This of course is only a guideline. The size and shape of your room will almost certainly
dictate a modification to the “ideal” set-up. Volume adjustments within the receiver will help balance your system.
Because it is difficult to distinguish the direction from where lower frequencies are created, you can place the subwoofer
nearly anywhere in the room. Placing the subwoofer closer to a corner or wall will increase the level of bass produced but
may also muddy the sound. You should experiment with different positions before settling on the one you prefer.

Speaker Size
Many of today’s receivers allow you to tell the receiver what type of speakers you are using. This is important since you
don’t want to waste the power across a full-frequency signal to a speaker that can only handle a limited range. Receivers
will typically ask you whether or not the speaker is “small” or “large”. In most cases, setting the speaker to “small” will
cause only frequencies above 100 Hz to be sent to the speaker. “Large” allows the full frequency range to be passed to
the speaker. Some receivers take this a step further and actually allow you to set the cut-off frequency. HTD Level ONE
speakers will almost always perform best when set to “small” or with a crossover point of 100 to 120 Hz.
In many receivers, setting a speaker to “small” automatically sends the low frequencies that would otherwise go to that
channel to the subwoofer connected to the LFE channel. Check the “bass management” section of your receiver’s
owner’s manual to be sure. This section should also address the options you have for utilizing the powered subwoofer in
audio-only applications.
Mounting Brackets
HTD Level ONE Main Speakers include U-shaped wall-mount speaker brackets. Hardware is included for mounting
where you have access to both sides of the wall or stud. You can also attach the speaker brackets to a stud from one side
using 1 1/2” wood screws. For safety, always mount these speakers on a wall that is reinforced from behind. Never
mount a speaker on a wall made of un-reinforced drywall or plasterboard. Consult a professional contractor if you are
unsure. These speakers can also be placed on bookshelves and most types of speaker stands.
NEVER PLACE A SPEAKER WHERE IT, OR THE CABLE CONNECTED TO IT, ARE WITHIN EASY REACH OF
CHILDREN OR PETS. ALWAYS USE GOOD JUDGEMENT AND COMMON SENSE WHEN PLACING A SPEAKER
WHERE PEOPLE OR PETS WILL HAVE ACCESS TO IT AS SERIOUS INJURY OR DEATH CAN OCCUR IF THE
SPEAKER WERE TO FALL.
Warranty
All HTD Speakers carry a five-year parts and labor warranty. Details of the warranty and return authorization process are
available on our web site. Your warranty registration occurred at the time your order was placed. There is no need to fill
out additional forms.

Connecting the Level ONE Powered Subwoofer
Line Level Connection
The Level ONE Powered Subwoofer allows for two connecting options. Most new home theater receivers include a
dedicated LFE or Subwoofer Line Level Output which should be connected to the Line Level inputs on the subwoofer.
Since this type of output on your receiver is a mono output (single RCA jack), use the included mono to stereo adaptor to
convert the mono signal into two identical signals, then connect the included stereo RCA cable from this adaptor to the
Left and Right line level inputs on the receiver. The Level ONE Powered Subwoofer requires that both the Left and Right
Line Level Inputs receive a signal to operate properly.
Speaker Level (high level) Connection
If your receiver does not provide a dedicated LFE or Subwoofer output, you can connect the powered subwoofer using the
Speaker Level inputs. Connect regular speaker cable (18 gauge or thicker) to the left channel output on the receiver and
connect the other end to the left (L) speaker level input on the subwoofer. Similarly connect the right channel from the
receiver to the right (R) speaker level input on the subwoofer. Then connect the left and right speakers from the speaker
level outputs on the subwoofer (instead of connecting the speakers directly to the receiver). This setup allows the low
frequencies to be reproduced by the subwoofer, while passing the full frequency range on the left and right speakers.

Using the Level ONE Powered Subwoofer Controls
Power
The power switch has two positions, off and on. When the power LED is lit, the power is on.
Level
The level control adjusts the volume of the subwoofer. When connecting the subwoofer using the Line Level inputs, first
set the volume level for the subwoofer in the receiver to a high enough level that the subwoofer receives a strong signal.
In most receivers this usually means setting the subwoofer volume almost all the way up. Then, with music playing and
the subwoofer’s Level control turned all the way down, slowly turn the level control on the subwoofer up until its volume
blends well with the other speakers.
If you connect the subwoofer using the speaker level (high level) inputs, set the level control to a level that balances the
subwoofer with the other speakers connected to the same output channel. Once set, the level control should not require
further adjustment.
