Thank you for purchasing the bar from the GO series. The bar is a

balanced USB audio DAC amplifier.

1. Audio format, frequency and sound effects LED

The LED colour scheme indicates the current sampling frequency

and audio format received by the GO bar from the music source.

Sound effect modes are also indicated.

LED Mode

White 44.1/48kHz

Tip: Sonically-hindering DSP is NOT used for XBass+ nor XSpace systems. They use the

highest-quality discrete components and operate purely in the analogue domain. Hence

all the clarity and resolution of the original music is retained.

The following 4 digital filters are available:

ringing

'STD' (Red) Standard, modest filtering, modest pre and

post ringing

'MIN' (Yellow) Minimum phase, slow roll-off, minimum pre

and post ringing

'GTO' (White) Gibbs Transient-Optimised: upsampled to

352/384kHz, minimum filtering, no pre

ringing, minimum post ringing

Note: If the GTO filter is selected, the only sample rate indicator showing will be

352.8/384kHz, indicating the upsampling operation of this filter.

4. Volume control and gain

To increase volume, press the + button, and to decrease it, press

the - button. Volume level is briefly displayed on the GO bar while

pressing one of the volume buttons, shown by the number of

white LEDs on at a time - from none to 6.

The increase or decrease of volume can be synchronised with the

volume of the mobile phone/computer. The connected device

will indicate a change of volume on its display if synchronisation

is on, and the device’s volume controls can additionally be used to

adjust volume. The GO bar’s volume buttons are still operational.

By default, the synchronisation feature is off. To switch this on or

off, press the settings button (5) for > 8s. On is indicated by the 6

white LEDs switching on in sequence from LED 1 and 6 to the

centre. Off is indicated by the 6 white LEDs switching off in the

opposite direction.

Turbo Mode increases the gain by 6dB. To switch this on or off,

press the + and - volume buttons together for ≥ 2s. Turbo Mode

on is indicated by 2 white LEDs increasing to 6 lighting up at the

same time for 2s. Normal gain is indicated by 6 white LEDs

diminishing to 2 lighting up for 2s.

Tip: For sensitive headphones and earphones, leave Turbo Mode off. For less sensitive

headphones, it may be appropriate to switch Turbo Mode on.

5. Settings and Digital filter mode

This button cycles between:

Off > XSpace > XBass+ > XSpace and XBass+ (short click). Please

refer to item 1 for sound effects LED indications.

Digital filter setting mode (long press ≥2s). Please see below.

Digital filter

To enter digital filter setting mode, press and hold the button for

≥3s. The MQA LED will flash with the currently set digital filter

colour (as shown in item 2). Press the + or - buttons (4) to change

the filter selection. A short press on the settings button (5) will

select and exit the filter setting mode.

3. iEMatch switch

iEMatch reduces the output level, so that even the most

sensitive In-Ear-Monitors (IEMs) can be matched to the GO bar.

= 3.5mm headphones

= off

= 4.4mm headphone

Tip: The GO bar and/or the headphone will not be damaged if the iEMatch switch is

adjusted incorrectly, but the attenuation level will not be correct.

6. S-Balanced 3.5mm headphone output

For connecting 3.5mm headphones. This is a single-ended

output.

7. Balanced 4.4mm headphone output

For connecting balanced 4.4mm headphones. This is a fully

balanced output.

8. USB-C input

The USB-C socket plays up to 32-bit 384kHz, has full MQA

decoding, and native DSD up to DSD256.

Tip: Because the Go bar is a high-performance gadget and the iPhone's power supply is

conservative, we recommend using an iPhone 8 or higher for reliable connectivity, and the

battery should be charged to 70% or higher.

Warning: If the GO bar’s volume synchronisation function is on, and the music source is

Tidal via Windows, please ensure that the Tidal setting of Forced Volume is off. With this

function on, there is no volume control possible, and the volume will be at maximum. This

has the potential to damage the connected headphone and/or your hearing.
