Connections

* Please also read instruction manual of audio device.
* Be sure to turn off the power to each device before connecting.
* The USB terminal of this product is self-powered (does not require power from a computer).

1. With reference to "Connection example", connect a computer and other devices to be used.
2. Insert the power cable into the inlet on this product and 100V AC outlet.
3. Turn on the connected devices.
4. Turn on this product. Wait until the power LED indicator turns from orange to green (about 60 seconds).
5. Select the device for playback using the input selector switch.
6. After turning down the volume on this product, connect the headphone to the headphone output terminal. For more information on headphone impedance and headphone terminals to be used, refer to "How to use headphone output terminals."

* If a headphone is inserted or extracted with loud signal input to this product, the power indicator will turn orange temporarily and the audio will be muted. This is not a failure; it is caused by the activation of the amplifier protection circuit. A short time later (about 60 seconds), the volume will be restored to the original volume level.
* If your headphone has a 3.5 mm stereo mini plug, you will need to use a conversion plug adapter. Please note that it may be difficult to pull some plug adapters out of the jack. See "Cautions" on page 16.

1. Play the playback device and adjust to the desired volume level using the Volume knob on this product.

2. Adjust the volume and the VU meter range selector switch so that the VU meter's pointer is within the display range. For more information, refer to "How to use a VU meter" (page 21).

* If you use the meter until the pointer goes off the scale, it may cause failure of the meter.

How to use headphone output terminals

Headphone Amplifier AT-HA5050H 120 Ω 82 Ω 33 Ω 0.1 Ω CED OUTPUT MPEDANCE A B 1 2 3 4 Headphone

This product has two headphone outputs.

Connect one headphone to output A, one to output B.

Select and use the output terminal to your liking with reference to the following examples.

Examples of use

To use 16 to 64 ohms impedance headphones:

Use the output terminal with ④ 0.1 ohms output impedance.

When you use the output terminal with low impedance, high-resolution, powerful sound will be produced.

When you use the output terminal with high impedance, rich sound in the low-mids will be produced.

To use 100 ohms or higher impedance headphones:

Use the output terminal with the output impedance of your choice.

When you use the output terminal with low impedance, high-resolution, tight sound will be produced.

When you use the output terminal with high impedance, rich sound in the low-mids will be produced.

To use balanced armature-based earbud headphones:

When balanced armature-based earbud headphones for a single unit are used, use any output terminal of your choice.

When balanced armature-based earbud headphones for two or more units are used, use the output terminal with ④ 0.1 ohms output impedance.

When an output terminal with high impedance is used, you may not get good frequency characteristics.

To use different impedance headphones and make volume levels uniform: (Connect two headphones to outputs A and B.)

Connect the higher impedance headphones to the output terminal with ④ 0.1 ohms output impedance.

Select the output terminal with ① 120 ohms, ② 82 ohms, or ③ 33 ohms output impedance, so that the volume level of the two headphones becomes the same. Since different headphones have different output sound pressure levels, you may not get the same volume level.

How to use a VU meter

The unit of measurement for a VU meter on this device is decibel (dB).

To check the output power, refer to "How to read levels against the range switch" and the conversion table below.

* If you use the meter until the pointer goes off the scale, it may cause failure of the meter.
