Thank you for choosing Denon. Modern flat-panel televisions are wonders of digital video, but leave little room for serious
sound reproduction. The Denon-engineered DHT-T110’s accurate, dynamically wide-range sound bridges the gap, with
spacious audio reproduction from Music and Movie modes, including Dolby Digital surround decoding, that bring television
and movie sound to life. DHT-T110’s inputs adapt to any television or system arrangement, with wireless Bluetooth® streaming for convenient audio playback from mobile devices. What’s more, an ingenious remote control learning solution lets you
continue using your familiar television or cable/satellite remote.
We’ve worked hard to make DHT-T110 the best performing product of its kind—and just as diligently to ensure it is the
simplest to set up and easiest to use.
You’re about to hear just how much you’ve been missing, but first, please take a few moments to leaf through this brief manual. You
probably think it is not really necessary, and you may well be correct, but doing so will help you get the best from the DHT-T110.
Please save your original shipping carton and packing materials if at all possible. Should you ever need to move or transport
DHT-T110, this is by far the safest way to do so.
Locating DHT-T110
DHT-T110 is designed to support most large flat-panel televisions up to 50" (with a foot base diameter up to 21 1/2 x 12 1/8” (546
x 308 mm)) and 60 lbs (27 kg). The television’s base needs to fit entirely within the flat top area of the DHT-T110. There is a "+"
mark on the top center of the cabinet. Use that to get the television base centered on DHT-T110.
You may also place DHT-T110 on a shelf, or furniture, above or below the screen. However, it should be centered left/right with
the screen, and ideally no more than a few inches above or below. DHT-T110 is not suitable for direct on-wall mounting. DHTT110 will often sound its best when the DHT-T110’s front grille is close to or flush with the front edge of the furniture or shelf on
which it rests (this eliminates unwanted sound reflections).
Not Centered
Base is too large
CAUTION: Allowing the base of your TV to hang over any edge of this speaker system increases the risk of the TV tipping, which may result in injury.
CAUTION: If your TV comes with an anti-tip device, install it according to the manufacturer’s instructions and adjust the tether as instructed
after placing the TV on top of the system. Installing an anti-tip device is recommended when using a TV with this product. If your TV did not
come with an anti-tip device, you can get one from most retail TV suppliers.
• If the TV base is too large to fit on top of the system- place the sound system in another location such as on an open shelf under the TV, but keep
it close to your TV so the audio cable will reach. You also could mount your TV on the wall above the system.
• Never place the equipment in an unstable location- The equipment may fall, causing serious personal injury or death. Many injuries,
particularly to children, can be avoided by taking simple precautions.
CAUTION: DO NOT place a CRT type TV on this system. It is not designed for use with this type of TV.

Connecting DHT-T110 to your television
DHT-T110 offers three audio inputs to route sound from your television to the DHT-T110.
Connect only one type of audio cable at a time.
Optical Digital Input (S/PDIF) —Connects to television’s optical digital out.
Coaxial Digital In (RCA jack)—Connects to television’s coaxial digital-audio.
Analog In 1/8" (3.5 mm) mini plug stereo—Connects to television’s rear panel audio out or headphone
output if no digital out available.
Which of the three inputs will be selected is determined by auto-priority. If only one input has signal present, that input will
play, but if more than one are active Optical takes priority over Coaxial or Analog, and Coaxial over Analog.
Optical Digital In – BEST
Use the supplied optical cable to connect your television’s optical digital output to DHT-T110’s Optical Digital Input. Other
components connected to the television, such as a DVD/Blu-ray player or cable/satellite tuner, will automatically play through
The optical connector looks square, but it is “keyed” and will only plug in one way; don’t force it.

Coaxial Digital In - BETTER
If your television lacks an optical digital out it will probably include a coaxial digital output. Use an “RCA”-type cable (not
included) to connect your television's coax digital audio output to DHT-T110’s Coaxial Digital In. Other components connected to the television, such as a DVD/Blu-ray player or cable/satellite tuner, will automatically play through DHT-T110.

Analog In 1/8" (3.5 mm) mini plug analog audio - GOOD
If your television has no digital audio outputs, connect its analog stereo audio output using the supplied 1/8" (3.5 mm) stereo
cable; if this output is in the form of dual RCA jacks (typically red for right and white or black for left), use the supplied adapter.
If no other audio output is available, connect the set’s headphone jack to the analog input using the supplied cable.

Important Note: Input Sensitivity (Analog Input Only)
The normal setting for this is “0 dB.” In rare cases a television’s analog audio output may be too strong. Should you hear
distorted, harsh, or “buzzy” sound from DHT-T110 via its analog stereo input, adjust the rear panel Input Level switch if you
continue to hear distortion.
If you connect multiple inputs to DHT-T110, the DHT-T110 will automatically select the one with the highest priority. For example,
if optical and analog ins are both connected with live signal, optical will play through the DHT-T110. If the optical source is
turned off, the DHT-T110 must be powered off and then back on in order to detect a different audio input.
Disable Your Television’s Speakers
Disable your television’s built-in speakers when using DHT-T110. Usually, this is accomplished via an on-screen setup menu on
your television. Look for an “Audio” or “Sound” sub-menu, and a “Speakers Off”, “Disable Speakers”, "External Speakers" or
similar menu item. Some televisions have a switch on the rear panel to disable the built-in speakers. If your television does not
have these functions, lower the volume of the television all the way down to 0, or mute the television.
Don’t leave the television speakers on so that both systems play simultaneously;
this will not yield sound that is louder or “better.”
The DHT-T110 Remote Control
A remote control is supplied with DHT-T110. Its keys duplicate DHT-T110’s front-panel buttons (see "The Controls on Top of
DHT-T110" on page 13), with one addition (Day/Night), and one deletion (the “Learn” key).

About DHT-T110's Automatic Power Modes
DHT-T110 will automatically “wake-up” whenever any of its wired inputs receives an audio signal. Simply turning on your
television will also turn on DHT-T110. (For Bluetooth playback you will need to turn on DHT-T110 manually using the remote
control or top panel. controls). Because of DHT-T110’s power saving design, the system takes five to seven seconds to turn
on from standby. Pressing either the front-panel Television Input or Bluetooth keys will also power up the DHT-T110. Press the
Power key again to return DHT-T110 to its low-power “standby” mode. DHT-T110 will automatically return to standby after five
minutes of not receiving any audio, for example, after you turn off your television set.
If you wish to change this auto-on behavior you may switch between the standard automatic wake-up/standby mode,
and a manual power on/standby mode. To change from one to the other, press-and-hold the front panel Power key for
three seconds. The power key LED will flash bright for three seconds, then illuminate steadily for three seconds, and then go
completely dark, indicating you have changed to manual power mode. Each time you repeat the Power-key press-and-hold it
will change to the other mode. In manual power mode DHT-T110 is switched to on or standby with a momentary press of the
Power key.
About the DHT-T110 Control Button LEDs
The eight LEDs illuminating the top panel control buttons flash or light in various patterns to indicate different functions.
Power Momentarily bright when DHT-T110 is turning on/waking from sleep; steadily dim while on/awake
(operating mode); steadily dark when DHT-T110 is “asleep” in standby mode; flashes when
toggling between manual- and auto-on/standby modes.
Television Input Momentarily bright when Television Input is selected, whether manually or automatically by
active signal at any wired input.
Bluetooth® Input Flashes bright, rapidly, while Bluetooth is “pairing” a wireless device; steadily bright
when selected.
The Bluetooth LED will flash bright, slowly, while attempting to re-pair a device that has passed out of range or
otherwise lost wireless contact, and blink rapidly to indicate a Bluetooth error (unable to pair). This will cease after 60
seconds or if any DHT-T110 key is pressed.
Learning Flashes when learning functions from your remote (see "Use Any Remote to Control your DHT-T110"
on page 16).
Listening Mode Flashes once when pressed at the front panel, and selects the next Listening Mode (see
"Listening Modes" below).
Mute Flashes bright continuously as long as Mute function is invoked.
Listening Modes
DHT-T110 includes three Listening Modes for different kinds of audio programs, room acoustics, or personal preferences. It also
has a special “Night Mode,” which enhances low-volume listening, which is described in the following section.
Select a Listening Mode using either Listening Mode key
(front panel or remote). Each keypress advances in sequence
through the three modes – Dialog, Music and Movie. DHT-T110’s front panel key LEDs momentarily display a pattern representing each newly selected mode. The following information describes the various listening modes, and shows an illustration
of the LED pattern displayed when that mode is selected.
Note: The LED displays used to indicate the various Listening Modes are simple horizontal display patterns—there is no
c­orrespondence between the lit LEDs and their underlying key functions.
Dialog mode highlights center-recorded sounds such as movie dialog, television a­ nnouncers, or musical
soloists; it is valuable for everyday television viewing.
Music mode widens the “soundstage” somewhat for a more enveloping, involving sound.
Movie mode deploys DHT-T110’s maximum processing for the “biggest” possible sound on action films or
other large-scale content.
Night Mode
Night Mode improves low-volume listening by subtly lifting softer sounds, and lowering very loud ones. While you may use
Night Mode whenever you like, for maximum dynamic realism from television programming, movies or music, leave night
mode turned off.
To engage Night Mode, press the Day/Night
button on the remote control press, or press and hold the front panel
Listening Mode button
for three seconds. When Night Mode is engaged, the LED pattern for the current Listening
Mode dimly lights. To exit Night Mode, use the same buttons in the same way. When DHT-T110 exits Night Mode, the LED
pattern for the current lsitening mode brightly lights.
Volume Change Indication
When you adjust DHT-T110’s volume from the remote control, the 8 front-panel LEDs momentarily function as a horizontal
“bar-graph” of the volume setting reached, illuminating from 1 to all 8 buttons, the latter indicating maximum volume.
Using Bluetooth®
DHT-T110 can stream music wirelessly, via Bluetooth, from any compatible Bluetooth device such as a mobile phone, tablet, or
laptop computer.
Pairing Your Bluetooth Device
Before you can stream Bluetooth audio to DHT-T110, you must pair your device to DHT-T110.
To pair the device to the DHT-T110 for the first time:
1 Press-and-hold the Bluetooth key (front panel or remote) for at least 3 seconds; the Bluetooth LED will begin
to flash rapidly.
2 Go to Bluetooth settings on your device. Make sure the device’s Bluetooth feature is set to “on”.
3 From the Bluetooth list on your device, select “DHT-T110”.
4 Playback audio on the Bluetooth source; you should now hear audio from the DHT-T110. DHT-T110’s Bluetooth key LED
will remain on as long as DHT-T110’s Bluetooth input is selected and active.
DHT-T110 can pair multiple Bluetooth devices; however, only one can play at a time. First come, first served. One Bluetooth
Source will need to be disconnected before another paired device can play.
Use Any Remote to Control your DHT-T110
It’s easy to “teach” DHT-T110 to respond to nearly any conventional IR (infrared) remote, so that you may continue to use your
favorite television or cable/satellite. You may prefer to teach DHT-T110 only selected commands, to avoid unintentional
operations and subsequent confusion among some household members. Some DHT-T110 owners teach only Volume Up/
Down and Mute, relying on the DHT-T110’s front panel, or DHT-T110’s own remote, for other functions.
Learning commands (using Volume up as an example):
1Press-and-hold the front panel’s Learn button for 3 seconds; its key LED will flash slowly.
2Now press the front-panel Volume up key; the Volume up key LED will also commence flashing slowly, in sync with the
Learn LED.
3Within 60 seconds, aim the “source” remote (for example, the television handset) from approximately 18" (0.5 m)
directly toward DHT-T110’s front panel, and press its Volume up key 4 times in slow succession; both flashing DHT-T110
LEDs will now light steadily for 3 seconds, indicating a successful “learn.”
Unlearning commands
1Press-and-hold the front panel’s Learn button for 3 seconds; its LED will flash slowly.
2Press the button you want to clear; the button's LED will also flash slowly, in sync with the Learn LED.
3 Press the learn button within 60 seconds; both LEDs will flash rapidly for 3 seconds. The command has been unlearned.
Seven of the eight DHT-T110 front-panel buttons can be taught to respond to an external remote. Simply repeat this threestep process for as many of the other DHT-T110 commands (each associated with a front-panel button) as you wish.
Note: Rapid blinking of the two LEDs indicates a failed “learn”. Press any other front-panel or DHT-T110 remote key to reset
learning, and start again. See the Troubleshooting section for tips to help you successfully teach DHT-T110 to recognize the
signals from your remote control.
Once you have programmed DHT-T110 to respond to your “everyday” remote controller, you may wish to put away the DHTT110 remote for safekeeping. If you do, we recommend that you remove the battery, and wrap it in a slip of paper, maskingtape, or similar to prevent accidental discharge and put it and the DHT-T110 remote someplace safe.
Some remotes can learn by pressing the remote key several times (up to four times)
Troubleshooting DHT-T110
DHT-T110 Does not power on
• Is the DHT-T110 plugged into a proven-live wall outlet? Try a lamp or other known-good appliance. Avoid using outlets
that are connected to switches or dimmers.
No television sound
• Is DHT-T110’s volume turned up? (Don’t laugh; we do this one ourselves all the time.)
• Is DHT-T110 muted (if so, the front panel Mute key
LED will be flashing).
• Is the DHT-T110 set to the correct source? A flashing Bluetooth® key LED on the front panel indicates DHT-T110 is
trying to “pair” to Bluetooth; press the Television Input key
to interrupt this and switch to television sound.
• Is the audio source a volume-controlled television or cable/satellite box output? If so, you must turn up the volume
of the television or cable/satellite box to send adequate signal-level to DHT-T110. (For this reason it is best to choose
fixed-level outputs where possible; some televisions have separate physical outputs, other employ on-screen menu
settings to manage this.)
• Check connections: remember that DHT-T110 auto-prioritizes multiple incoming signals, selecting optical-digital, coaxial-digital, and analog-mini plug, in that order. Confirm that the television is routing audio to the appropriate output;
there may be TV-menu settings to manage this.
• Check the signal format. Dolby Digital (5.1ch), PCM (32kHz-96kHz) is supported.
Distorted sound from the DHT-T110
• If the signal source is a volume-controlled output, turn it down a couple of steps from maximum.
• If using the analog stereo input, check the rear-panel Input Sensitivity switch setting (see page 11).
• Check the signal source to be sure the distortion is not originating there.
• If DHT-T110’s volume is set to its maximum, turn it down a few steps.
Trouble teaching DHT-T110 remote control commands
• Make sure the source remote is working properly in the first place; check batteries; confirm direct operation.
• Move the DHT-T110 and source remote out of bright sunlight or powerful room lighting (too-bright light will impede
infrared-signal transmission).
• Be sure to hold the “source” remote steady, 12 - 18" (0.3 - 0.5 m) in front of the DHT-T110, on its level, with the remote’s
IR emitter (usually a smooth black-plastic area across the end you point toward the television) aimed straight and level at
the center of DHT-T110’s front panel.
• Press and release source-remote keys deliberately; hold each keypress down for a half-second or so, and pause a
second between repetitions.
• Remember that while DHT-T110 can learn almost all IR (infrared) remote commands, there remain a few rare code
formats that cannot be taught (much like some engineers we know).
Television speakers keep getting turned back up
• Disable the television’s speakers (usually a setup-menu option, but a rear-panel switch on some televisions). If this is
not possible, the problem is likely that the television responds to press-and-hold (ramping) volume commands more
quickly than the DHT-T110; in this rare case use DHT-T110’s front-panel or supplied remote to turn the DHT-T110's
volume up.
Trouble Pairing Bluetooth®
• Make sure DHT-T110 is in Bluetooth pairing mode (Bluetooth key LED should be flashing).
• Make sure your Bluetooth source is in Bluetooth pairing mode (see the source’s instructions).
• Bluetooth source device must support A2DP (Advanced Audio Distribution Profile); some Bluetooth products (some
tablets, some GPS units, for example) will thus work with Bluetooth keyboards or headsets but are not capable of
high-fidelity audio playback.
• Keep your Bluetooth source within 10 ft (3 m) of DHT-T110 while pairing.
• Power cycle the Bluetooth device (complete power off and “hard-reboot”), and try to pair again.
Bluetooth connection problems
• If a Bluetooth fault occurs (the device moves out of range, or stops playing due to low battery or user input),
DHT-T110’s Bluetooth LED again blinks rapidly; the DHT-T110 will automatically attempt to re-connect, and will resume
playback when the Bluetooth source is in range. Note: On some devices you will need to press play again. Bluetooth’s
effective wireless range varies with the source; 30 to 40' (9 - 12 m) is typical. If the source moves out of range, DHT-T110
will continue trying to re-connect it for 4 minutes; after that interval you will have to re-connect, as above.
• Make sure DHT-T110 is not paired to a different Bluetooth source device.
• Make sure your desired Bluetooth source device is actually playing music or another audio program and is paired to
DHT-T110 and not some other device.
• On a multifunction source device such as a tablet or mobile phone, not every program or “app” may support Bluetooth
audio broadcast (consult the instructions for the program or app).
• Consider possible sources of interference, particularly those operating at 2.4 GHz (Wi-Fi routers, microwave ovens, landline cordless telephones); power down suspects one at a time to identify a culprit. Often, repositioning an interfering
device to another room, or even across the room, will restore Bluetooth function.
DHT-T110 takes several seconds to turn on
• The DHT-T110’s power saving design puts the unit into standby mode after five minutes of no sound. DHT-T110 takes a
few seconds to start up the next time audio plays
Factory reset
• Unplug unit from wall.
• Hold down Vol _ (minus) button.
• Plug into power again.
• Standby button light will blink fast for several seconds indicating that the system has been reset.
• Clears Bluetooth pairing, remote learning, audio mode.
