Controls and Functions

Front Panel

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.

3. VU METERS
   Indicates the audio output level of the left and right channels.

4. BASS CONTROL
   Adjusts the volume level for the bass output.

5. TREBLE CONTROL
   Adjusts the volume level for the treble output.

6. HEADPHONE OUTPUT
   The headphone output allows you to listen to any input privately without playing audio through your speakers. The output accepts ¼” TRS headphone connectors. Plugging in headphones here will cut off the signal to the speakers and SW OUT [10]. NOTE: To avoid accidental damage to your head-phones or speakers always turn down the volume before connecting or disconnecting headphones.

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

8. SOURCE INPUT SELECTOR
   Press the corresponding input button to select the desired source. The corresponding light will illumi-nate when the input is selected.
   NOTE: PC-USB input will not be selectable unless there is a device connected to the unit
   and powered on.
   Rear Panel
   

9. DIGITAL (OPTICAL) INPUT

10. SUBWOOFER OUTPUT

    • Use a single RCA cable to connect the SW OUT to a powered subwoofer or separate subwoofer amplifier.
    • This will output a full range mono signal and the volume output will change depending on the position of the front panel volume control.
    • NOTE: The output will signal will be interrupted when headphones are connected on the front of the amplifier.

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

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 the internal fuse located in the IEC socket should also be changed. In most 220V applications a separate power cord will be required and is not included.

14. PC-USB INPUT

15. DIGITAL (COAXIAL) INPUT

16. LINE LEVEL (AUX) INPUT

17. PHONO INPUT

18. SPEAKER OUTPUTS
    Using insulated 2 conductor wire to connect to speakers. The polarity, positive (+), and negative (-) for all speaker and amplifier connections must be consistent so both the left and right speakers are in phase.
    NOTE: The speaker outputs are not bridgeable.

19.  AC POWER INPUT

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.

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 your left 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 the end of the corresponding terminal.

Connecting Speaker Wires

1. Strip about 3/8″ of insulation from the end of each speaker 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 control- lable by the front volume knob. Using a single RCA cable you can connect to the line level input on a powered sub-woofer 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 from being 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 your headphones. Always turn down the volume knob before unplugging headphones to avoid accidental output to your speakers or startling any cats napping nearby.

Connecting Sources

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 it to 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 the Bluetooth input is selected on the HTA100.
2. Using a smart phone, tablet, computer, or other device capable of transmitting Bluetooth audio, go the devices 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 can begin streaming your favorite music from up to 30 feet away.
