Introduction
Dear Customer,
Human Audio would like to thank you for choosing the Tabla computer audio device. The Tabla is an
internal battery powered USB interface for High Definition Audio.
The development of the Tabla at Human Audio was based on the belief that the missing link between computer
audio and audiophile audio was an extraordinary USB converter. Chances are you never heard your DACs
potential if you haven't used it with a Tabla.
With this new device, you are able to connect an existing audiophile or even high-end DAC (such as our new
MUTO HD DAC ) with the computer or music server in order to hear "BIT PERFECT" listening audio
streams up to 24bit/192kHz. The Tabla needs only one free USB 2.0 port on the PC orMAC. The output is a
coaxial digital (BNC) to the DAC although we include a BNC/RCA adapter with your unit.
Based on the Human Audio philosophy this device is pure battery powered with the built-in two-piece
highgrade Lithium-Iron-Phosphate (LiFePO4) cells. The charging is fully automated without any external
device since the Tabla uses the USB power for charging purpose during idle.
Tabla provides ultimate audio performance using these TWO built in batteries of the highest grade for the
lowest ripple and the least noise in the output performance, a very advanced ripple smoothing technology is
incorporated when using the USB power while the battery is being silently reloaded, ultra-low jitter discrete
onboard clocks for 44.1kHz and 48kHz multiples, a specialized pulse transformer on its real 75 Ohm BNC
output and of course one of the best USB-Audio algorithm available on the market (developed by M2Tech).
A power supply without any power network interferences:
Our products are power supply independent, battery operated and free of any disturbing “mains” circuits
during operation. This technology is utilized in order to ensure that the listener enjoys the same high quality of
sound any time of day, anywhere in the world. With Human Audio devices, many expensive and unstable
power supply regenerator, and power cable become useless. In addition, for those who would like to relax and
enjoy their music without worrying about short battery life - we have the solution! Thanks to it’s optimized
energy consumption, our products offer up to 12-18 hours continuous listening on a single charge.
The devices are designed to be simple and easily controlled by the listener while it displaying monitoring
information..

You cannot use the unit on a computer without installed device driver. You can find the latest drivers on the
manufacturer's website or the importer’s website. http://www.trueaudiophile.com/tabla-drivers/
•
Do not use a USB cable longer than 3 meters (10 feet). The recommended length is between 1 and 1.8 meters (3-6
feet).
•
The recommended length of S/PDIF cable is between 1 and 3 meters. (3-10 feet)
•
The BNC connection is strongly recommended. While an RCA connection isn't as accurate you can use it.
•
Do not use a USB cable without "USB 2.0 Hi-Speed" certificate. We cannot guarantee the right operation with
non-standard (or DIY) USB cables.
•
The unit cannot be switched-on without being connected to a powered USB port. This is preventive protection in
order to save the internal batteries from deep discharge.
•
The right connecting sequence and switch-on:
1. Connect both ends of the S/PDIF cable (from the TABLA to the DAC unit)
2. Connect both ends of the USB cable (from the computer to the TABLA)
3. If the device driver is already installed then you can switch-on the unit.
4. If the driver is not automatically selected as output then manually select it.
•
Before disconnecting the unit from the computer, stop playback first and release the device in the OS.
Before switching-on the unit, please make sure that the computer is working and the
USB and the DAC are connected properly!
Never disconnect the unit from the computer during playback! Otherwise, the unit
and the OS can be damaged!
Before you switch on/off the unit, we recommend decreasing the volume level.
If the device is not used regularly it is recommended you completely charge the batteries
at least once a month to maximize the battery life. (just leave it connected to a powered
USB port for at least for 8 hours)

LED indicator lights & charging
There are two indicator light source on the front panel:
•
•
"BAT" > Battery
"CHG" > Charge
The possible light signals from BAT:
- NO light: it means:
1. The device is switched-OFF
- GREEN light: : it means:
1. The unit is switched-ON
2. The battery level is OK
- RED light: it means:
1. The unit is switched-ON
2. The battery level is LOW
The possible light signals form CHG:
- NO light: it means:
1. The USB charging is NOT active
- YELLOW light: it means:
1. The USB charging IS active
2. The unit is NOT in clean battery powered mode
(these two states are available in switched-on and -off mode too)
- Flashing RED light*: it means:
1. The battery level is CRITICAL LOW
2. Need to connect to powered USB port ASAP
(this state is available in switched-off mode only)
*Above mentioned Flashing RED state usually appears ONLY when the unit has not been used
for several weeks or months. Under normal usage a user will never see that light.
In longer periods of unuse (weeks or months) in switched-off mode, the CHG light goes Flashing
RED to prevent the internal batteries form deep discharge and serious damage, you NEED TO
connect the unit to powered USB port as soon as possible. If you do not want to use your audio
computer you can plug it into any USB hub or active computer USB port for charging.

Automated charging features
•
IDLE CHARGING:
When the unit is in IDLE state (switched-on, but actually is not in playback mode – playing music) the
internal controller detects this and immediately begins charging from the USB port. In this case the BAT
light is GREEN and the CHG become YELLOW. When playback resumed, the CHG YELLOW light
goes out. If playback is NOT going on, then the YELLOW light stays on even when the battery reaches
full capacity, because at the end of charging the circuit goes into trickle charge mode for optimal
battery life.
•
LOW battery CHARGING:
When the internal batteries reached LOW level capacity, and the BAT light goes RED from GREEN, the
automatic charging starts, even if the playback was going on. In this case the BAT light is RED and the
CHG light become YELLOW. After a while (~90-120mins) the CHG light goes out (if the playback is
going) and the BAT light become GREEN again and the unit will be clean battery powered mode again.
This is not means that the batteries have full charge, but it has enough capacity for about 3-4 hours of
clean battery powered playback again. In order to get fully charged batteries, please see the next step.
•
FULL CHARGING (forced charging):
If you would like to get fully charged batteries, please leave the Tabla connected to a powered USB port
without playback for 8 hours. You can do this when the unit is switched-on or switched-off as well.
In case of switched-off: the CHG YELLOW light means that the unit is connected to the charge, BUT
again, the YELLOW light stays on when the battery reaches full capacity, because at the end the circuit
provides a trickle charge.
Since the charging process is about 5 times faster than discharge, assuming average listening
habits, you usually are not required to charge the unit in forced mode.
The unit has a built-in circuit to prevent against overcharging, so you can leave it connected to a
powered USB port at all times without any problem.
The internal LiFePo4 batteries have NO memory effect at all, so no need to do any
maintenance on it.
The recommended state for storage is "Fully Charged". To maximize the lifetime of the
batteries, do not leave the unit connected to an "Unpowered" USB port for long periods at
a time.

Configuring the computer
Configuring a PC with Windows XP
A PC with Windows XP can use hiFace in two different ways: Direct Sound (DS) and Kernel Streaming (KS). The former
is suitable for players which can’t operate in Kernel Streaming mode (such as Windows Media Player and iTunes) or for
Internet streaming, while the latter can be chosen (for better performance) with players which can operate in Kernel
Streaming mode (such as FooBar, Winamp, Monkey Media, JRiver).
Configuring for Direct Sound with Windows XP
Connect hiFace to your PC. Then, go to the Control Panel and launch the Sound and Audio Peripherals utility. Select the
Audio tab. In the Predefined Peripheral drop-down menu of the Playback area, select “KS hiFace” (see figure 11).
Figure 11
Then, select the “Voice” Tab. Again, select “hiFace Kernel Streaming” in the drop-down menu of the Playback area. Click
on OK button. Please be advised that even if the peripheral is listed as “kernel streaming”, it will operate in Direct Sound
mode when listed here. From now on, unless hiFace is disconnected or settings are changed again, hiFace is the audio
peripheral all audio programs will use when operating in direct sound mode.

_________________________________________________________________________________________________
Configuring for Kernel Streaming with Windows XP
Kernel Streaming has no standard setting in Windows XP. KS must be selected in the specific player you choose to use.
For example, when using FooBar, with hiFace connected to the PC, go to the File/Preferences/Playback /Output tab and
select “KS: hiFace” as output device. Other players will require different settings (see later).
Using the unit in both Kernel Streaming and Direct Sound mode.
When hiFace is selected as predefined audio peripheral, it is possible to use it in Kernel Streaming mode, too, with a
caveat. When using it in KS mode, it is necessary that no other application access hiFace in DS mode. If this happens,
Windows XP’s Kernel Mixer takes control of hiFace’s driver and from then on, no KS application can access hiFace
unless the PC is restarted or hiFace connection to the PC is cycled.
Configuring a PC with Windows Vista or Windows 7
A PC with Windows Vista or Windows 7 can use hiFace in three different ways: Direct Sound (DS), Kernel Streaming
(KS) and WASAPI. DS is suitable for players which can’t operate in Kernel Streaming mode nor with WASAPI or for
Internet streaming; KS can be chosen (for better performance) with players which can operate in Kernel Streaming mode
(such as FooBar, Winamp, Monkey Media, JRiver). WASAPI (Windows Audio Standard API) is a standard interface for
audio players, which allows getting the same performance of KS with applications that cannot operate in KS mode, at the
cost of higher CPU load.
Configuring for Direct Sound with Windows Vista or Windows 7
Open control Panel and select Hardware and Sounds. Under Audio, click on Manage Audio Devices. The following
windows will appear, in which hiFace is listed. Set hiFace as predefined device. Then, click on OK.

Configuring for Kernel Streaming with Windows Vista or Windows 7
As for Windows XP, Kernel Streaming has no standard setting in Windows Vista and Windows 7. KS must be selected in
the specific player you choose to use. For example, when using FooBar, with hiFace connected to the PC, go to the
File/Preferences/Playback /Output tab and select “KS: hiFace” as output device. Other players will require different
settings (see later).
Configuring for WASAPI with Windows Vista or Windows 7
As happens with Kernel Streaming, WASAPI cannot be directly accessed. WASAPI must be selected in the specific
player you choose to use. For example, when using FooBar, with hiFace connected to the PC, go to the
File/Preferences/Playback /Output tab and select “WASAPI: hiFace” as output device. Other players will require different
settings (see later).
Configuring a Mac
Go to System Preferences and select Sounds. The following windows will appear. Select hiFace for output as indicated in
figure 13.

Configuring the player for Kernel Streaming: some examples
FooBar
To use FooBar in KS mode it is necessary to download the DLL for Kernel Streaming from the FooBar2000 website and
install it in the Components sub-folder inside FooBar2000 main folder in your hard disk. The DLL can be found at
http://www.foobar2000.org/components/view/foo_out_ks (click on Download). It is a zip folder, which contains the DLL.
Extract it from the zip and copy to the Components folder. Then, restart FooBar, go to the
File/Preferences/Playback/Output window and set parameters as in figure 14.
Figure 14
Winamp and MediaMonkey
These two players are actually the same player with different skins, so they can share the same plug-ins. A freeware plugin for Kernel Streaming by Steve Monks is available on the Internet (http://www.stevemonks.com/ks_plugin/plugin.html)
that can be used to enable Kernel Streaming operation with these players. Download the zip file, extract the dll file and
copy it into the Plugins folder inside Winamp main folder. With hiFace connected right-click on Winamp and select
Display/Select Plug-ins. The Preferences window of Winamp will open (see figure 15).

Explanations
In this chapter, there are explanations for some of the terms and abbreviations mentioned in the manual
OS:
Operating System
PC:
computer with Windows Operating System
MAC:
computer with Mac OSX Operating System
LED:
abbreviation for light emitting diode
BNC:
professional connection for low-level digital and analog signals with right signal termination. In
this case much more accurate than RCA connection
RCA:
asymmetric coupling which provides connectivity (pin 2: signal and ground)
USB 2.0:
universial Serial Bus (USB) 2.0 is a complete overhaul of the Universal Serial Bus
input/output bus protocol, which allows much higher speeds than the older USB 1.1 standard
did. The goal of the new serial bus is to broaden the range of external peripherals that can be
used on a computer. A hard drive can easily hit the USB 1.1 bottleneck whereas it now
becomes more 'usable' under USB 2.0 conditions.
