Connections

Connecting the Power Cable
Before connecting the main power cable, make sure that the voltage selector switch is set according to your local volt-age. 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.
