Rear Panel

1. Line Level Aux Inputs
2. PC-USB Input
3. Subwoofer Output

Front Panel

1. Source Selector
   Turn this knob to select between different sources.

2. Volume Knob
   Turn this up to begin experiencing the warm natural tone generated by the tube preamplifier.

3. Bluetooth Antenna
   During setup, turn the Bluetooth antenna to the upright position for optimum signal reach.

4. Line Level Aux Inputs

5. PC-USB Input

6. Subwoofer Output
   Use a single RCA cable to connect the S.W. 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.

7. 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.

8. Power Switch
   Turns the device on and off.

9. AC Power Input

10. 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 S.W. OUT [6].
    NOTE: To avoid accidental damage to your headphones or speakers always turn down the volume before connecting or disconnecting headphones.

Connections

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 HTA20’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 the ground. The HTA20 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 S.W. OUT connection on the rear of the HTA20. 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 HTA20. 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 S.W. 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 HTA20 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.

Bluetooth as a Source

1. Make sure that the input selector is set to Bluetooth.
2. Using a smartphone, tablet, computer, or another device capable of transmitting Bluetooth audio, go to the device’s settings and scan for available Bluetooth devices.
