Welcome

Thank you for purchasing the Dayton Audio HTA100 Integrated Stereo Hybrid Tube Amplifier. This amplifier has
been designed to make it easy for anyone to enjoy the warm, natural sound quality of vacuum tube amplification
without the size, power consumption, and price of using traditional tube amplifiers. The HTA series from Dayton Audio
achieves this by combining vacuum tubes in the preamp input section with a modern power efficient solid state Class A/B
output power amplifier. Additionally, each amplifier includes multiple analog and digital inputs for connecting modern
devices such as computers with the classic sound of tube amplifiers.

7. VOLUME CONTROL
Turn this up to begin experiencing the warm natural
tone generated by the tube preamplifier.

1. POWER SWITCH
Turns the device on and off.
2. POWER INDICATOR
The ring surrounding the power switch will
illuminate amber when the unit is turned on.

8. SOURCE INPUT SELECTOR
Press the corresponding input button to select thedesired source. The corresponding light will illuminate when the input is selected.

to a powered subwoofer or separate subwoofer
amplifier.

15. DIGITAL (COAXIAL) INPUT
16. LINE LEVEL (AUX) INPUT
17. PHONO INPUT
18. SPEAKER OUTPUTS
Using insulated 2 conductor wire to connect tospeakers. The polarity, positive (+), and negative (-)
for all speaker and amplifier connections must beconsistent so both the left and right speakers arein phase.

This will output a full range mono signal and thevolume output will change depending on the positionof the front panel volume control.
NOTE: The output will signal will be interrupted
when headphones are connected on the front of theamplifier.

NOTE: The speaker outputs are not bridgeable.

11. BLUETOOTH ANTENNA
Connect the supplied Bluetooth antenna here for
optimum signal strength.

19. AC POWER INPUT

12. GROUND TERMINAL
13. AC VOLTAGE SELECTOR SWITCH
The unit is set at the factory for 110V operation. For
220V operation, move the voltage selector switch
to the 220V position. When operating at 220V theinternal fuse located in the IEC socket should also
be changed. In most 220V applications a separatepower cord will be required and is not included.

Connections
Connecting the Power Cable

Before connecting the main power cable, make sure that the voltage selector switch is set according to your local voltage. Incorrect setting of the voltage selector switch could cause damage to the amplifier and has a potential risk of fire.

6

Connecting Speakers
The amplifier can power speakers with a minimum impedance of 4Ω. Using high quality two conductor speaker wire
connect your speakers to the binding posts on the rear of the unit.
Connect the HTA100’s left speaker terminals marked “L-” and “L+” to the corresponding “-” and “+” terminals on yourleft speaker. Repeat the same process for the right channel.
Note: Never connect the negative terminals together or to ground. The HTA100 is not designed to operate in a
bridged mode and attempting to do so may damage the amplifier.

Connecting Banana Plug Cables

1. Tighten the knob.
2. Insert the banana plug terminated cable into theend of the corresponding terminal.

Connecting Speaker Wires

1. Strip about 3/8" of insulation from the end of eachspeaker wire and twist the bare wires of the cable
together.
2. Unscrew the knob before inserting the bare wire into
the hole in the side of each terminal before tightening
the knob to secure the wire.

Connecting A Subwoofer

If you really want to feel the bass or just want to bother the neighbors you can add a subwoofer using the SW OUT
connection on the rear of the HTA100. This signal is full range and will send a mono summed signal that is controllable by the front volume knob. Using a single RCA cable you can connect to the line level input on a powered subwoofer or to any external subwoofer amplifier to power passive subwoofers.

Connecting Headphones

Headphones can be connected to the ¼" TRS connection on the front of the HTA100. This is great for listening to any
source and enjoying the classic warmth from the tube preamps. Plugging in headphones will stop any signal frombeing output to the speaker output terminals or SW OUT.
Note: To avoid damage to headphones or your hearing make sure to turn down the volume before plugging in yourheadphones. Always turn down the volume knob before unplugging headphones to avoid accidental output to yourspeakers or startling any cats napping nearby.

TURNTABLE

The HTA100 is capable of receiving signals directly from a wide variety of sources. Using high quality cables will
ensure the best possible transmission from your connected devices.

Connecting a Turntable

The HTA100 is capable of connecting directly to most turntables without the addition of an external phono preamplifier.
1. Ensure that your turntable is set to output a phono signal. Many modern turntables have the ability to output
either a line level signal or a phono signal. If your turntable is set to output a line level signal please connect itto the AUX input on the HTA100.
2. Remove the covers from the PHONO RCA plugs and connect the turntable to the phono input.
3. Connect the ground wire of the turntable to the ground terminal on the rear of the HTA100 (if applicable).

Bluetooth as a Source

1. Connect the Bluetooth antenna to the BT ANTENNA port on the rear of the unit. Also make sure that theBluetooth input is selected on the HTA100.
2. Using a smart phone, tablet, computer, or other device capable of transmitting Bluetooth audio, go thedevices settings and scan for available Bluetooth devices.
3. Look for and select “HTA100” in the device list and begin pairing. The Bluetooth source light on the HTA100
will flash until a device is paired.
4. Once the Bluetooth source light stops flashing and your device indicates that you are connected you canbegin streaming your favorite music from up to 30 feet away.
