Thankyou for choosing the

TaKo Electronics EBi

Direct Interpolation digital to analog converter(DAC).

The EBi is a world-class digital to analog converter(DAC) which will allow you to rediscover your digital

music collection,whatever you use with a CD player, DVD player, Digital Media Jukebox or PC as your source.

The EBi provides a vast improvement over most digital signal source.

Please read this manual thoroughly to make the most of your DAC.

Included with the TaKo Electronics EBi retail package you will ﬁnd the following:

- TaKo Electronics EBi Digital to Analog converter

- One IEC power cable to suit your AC power point

- One USB to USB-B cable

- User manual

The EBi USB DAC is world-class quality, stereo digital to analog audio converter. It features non-oversampling and direct interpolation modes, optimized for 44.1/16bit (Philips CD redbook) - the most readily avaliable and popular digital audio format in the world. It also supports sampling frequencies up to 96Khz/24bit.

The EBi is a DAC for all music lovers to rediscover their music library, with amazing 3D imaging without typical digital ‘harshness’ and a pure focus on musicality, not ‘HIFI’.This is achieved via a combination of factors:

- Non-oversampling and direct interpolation topology.

- Circuit layout designed to maintain the highest digital signal intergrity posible, with all digital signal processing being performed on a single silicon die,an extremely short signal path and use of advanced high speed programmable logic device.This ‘shortest path’ philosophy also appied the analog section of the circuitry.

- The implementation of a direct interpolation method, which time multiplexes the output of 4 individual DACs to achiee a perfect impulse response without ringing, resulting in an even smoother sound than other contemporary non-oversampling DACs. The listener can switch between non-oversampling and direct interpolation at their leisure.

Quick Start Guide

1.Turn off all other audio components.

2.Plug an IEC power cable into the IEC inlet (marked as “AC power”) on the rear of the EBi.

3.connected the output from a digital source to either the coaxial,optical or USB input of the

Ebi.In the case of USB input from a PC,the PC will automatically recognize the connection and pormpt

the user to accept the EBias a system audio output.

4.Connect analog output of the EBi to your pre-ampliﬁer or reciever.

5.Turn the volume of the pre-ampliﬁer to minimum/zero and turn on your source.the pre-ampliﬁer and

power ampliﬁer,and press the power button on the EBi.

6..Ensure the pre-ampliﬁer has the EBi selected as analog input.

7.Begin playback of music on the digital source. Slowly turn the volume of the pre-ampliﬁer up to a

comfortable listening volume.

8.Enjoy!

Read this before operation

-Place the unit in a stable location near the audio system that you will use.

-As the unit may become warm during operation, always leave sufﬁcient space around the unit for ventilation.

Make sure there is at least 20 cm (8”) of space above and at least 5 cm (2”) of space on each side of the unit.

Do NOT place anything such as a CD, CD-R,LP, cassette tape etc. on top of the unit.

-The voltage supplied to the unit should match the voltage as printed on the rear panel.

If you are in any doubt regarding this matter, consult an electrician.

-Choose the installation location of your unit carefully. Avoid placing it in direct sunlight or close to a source of heat.

Also avoid locations subject to vibrations and excessive dust, heat, cold or moisture.

Power/Input button/Power on indicator

This button cycles through all the avaliable inputs and power on/off.

Red indicator will light up when power is on.

Non-oversampling/Direct interpolation button (indicator)

Input sequence:power off=>Coaxial in=>Optical in=>USB in=>power off

This button toggles between Non-oversampling and Direct Interpolation mode.

Green indicator will light up when the Direct interpolation mode is active.

Polarity button (indicator)

This button toggles analog output Polarity. If you need to correct a phase error on both channels,

Press the Polarity button to reverse the phase of the analog output.

Yellow indicator will light up when the phase is inverted.

Lock Indicator

Lock indicator will light up when Signal is locked to SPDIF (coaxial/optical) and USB input is

recognize with PC.

Coaxial input Indicator

Coaxial input indicator will light up when Coaxial input is selected.

Input conﬁguration

Most source equipment (transports) such as CD players or PC soundcards are ﬁtted with a signal digital

output ,usually on an RCA connector or an optical output.

Using the appropriate cable described under “Connections”,connect your digital source to matching

input on the EBi’s rear panel.Press the input/power button repeatly until the input options shown on the input

indicators,the options are -Coaxial,Optical and USB.

The EBi will automatically lock to the digital source. When a lock is being obtained ,the Lock indicator will lit.

The EBi also accepts USB signal.

To use USB, just connect a Type-B teminated USB cable (suppied) to a USB port on a PC or Mac.

The EBi will be recognized automatically by the operating system.

USB audio input

-The USB audio input is designed for use with computer or sound server.nothing useful will happen

if you connect the input directly to MP3 player or ﬂash drive.
