Resonessence VERITAS User manual

VERITAS User Guide
Software version 1.0.1
Introduction
VERITAS is Resonessence’s latest Digital to Audio Convertor (DAC). It uses the second generation ESS
“PR ” series of ESS’s SABRE DACS. It is the first product to market that uses the HyperStream II digital
modulator. This time it is about the sound, the results are in: 19 out of 20 audiophiles judge the sound
to be improved. VERITAS delivers this improved sound.
Overview
VERITAS accepts digital data via AES, S/PDIF (2 sources, RCA 1 & 2) , TosLink (T RX) and USB
interfaces. ver USB it uses Audio 2.0. Internally, VERITAS processes data up to 384ks/S within a 64
bit data path. VERITAS is a hardware engine – to manage noise, power consumption, clock jitter and
audio artifacts the absolute minimum of digital activity is used.
VERITAS is always-on – there is no power switch – the hardware boots-up on application of the
power. VERITAS accepts world-wide power specifications: there is no need to set 120v/240v or
similar. Always-on increases lifetime and audio quality – temperatures changes are the source of
electronic degradation, and always-on minimizes electrical and thermal stress. Despite being always-
on, VERITAS meets the most stringent EEC power limitations: a fraction of a watt is consumed when
the unit enters the sleep mode.
VERITAS delivers the Stereo analog audio output to differential XLR and single-ended RCA analog
outputs simultaneously. The Red RCA is the single-ended 2V RMS analog output to the Right Channel,
the White RCA is the single-ended 2V RMS output to the Left Channel. The male XLR output nearest
the edge of the unit, on the right when viewed from the front, is the differential 4v RMS analog
output to the Right Channel, the male XLR output nearest the center of the unit, on the left when
viewed from the front, is the is the differential 4v RMS analog output to the Left Channel.
VERITAS requires the Resonessence Audio 2.0 driver on MS Windows, on the MAC computers no
special driver is needed. Refer to the Resonessence WWW site for the Audio 2.0 driver on Windows.
Resonessence may update and improve the VERITAS software from time to time. You may check for
the updates, download and install them from the WWW site.

Operation Notes
•The choice of which is the major parameter and which are the minor parameters is changed by
pressing the menu button on the IR Remote.
Five digital data sources available and “sleep”, or low power mode, is selectable.
•Data sources and sleep mode are selected by pressing the centre of the ring on the IR Remote.
•Each press of the centre button cycles through the data source and sleep mode in sequence:
Sleep => T RX (TosLink ptical input) => RCA2 (S/PDIF Bottom range socket) => RCA1 (S/PDIF
Top range socket) => AES (Female XLR) => USB (Type B connector, USB Audio 2.0) => Sleep
Volume level is adjustable via the Rotary Knob on the front of the unit, or via the “Up” and “Down”
dots on the IR Remote ring. (“Up” at the 12 o’clock position, “Down” at the 6 o’clock position). The
volume control is digital, operating in a 64-bit data path. For audiophiles who prefer to use an analog
volume control, VERITAS provides a FIXED mode. If the volume is increased above 0db the unit enters
FIXED mode where full-scale analog output (2V RMS RCA and 4V RMS XLR) is delivered for full-scale
digital input, digital volume control is bypassed.
Remote Control
An Apple IR Remote is included with your unit. This is a 'standard'
remote meaning that no reprogramming has occurred.
Figure 1 here above shows the function keys of the remote.
Front Panel isplay
Three parameters are displayed simultaneously on the VERITAS display:
Volume level, Data Rate and Data Source. The display is divided into
three sections: the major parameter is displayed in large characters at
the top centre, the two minor parameters are displayed bottom left and
bottom right in smaller characters.

requests to change the volume level are accepted from the rotary knob, from the IR Remote and also
from the computer volume control events – such as keyboard volume up/down and mute.This allows
applications such You Tube, FooBar etc to change the volume level within the VERITAS unit. Similarly,
volume control events from VERITAS are received by the application and change its volume level.
However, FIXED mode ignores any USB instructions to change volume level (in FIXED mode the only
computer issued USB command responded to is “mute” and “unmute”).
Certain application on the computer (such as FooBar) additionally respond to commands from
VERITAS: Pause/Play and left/right presses on IR Remote will cause the player to pause, and skip to
next or previous tracks respectively.
Turning the VERITAS unit On
Simply plug your unit into a power outlet and the logo lens will briefly turn red and the software
version installed on the unit will be displayed on the LED Screen before the logo turns blue to
indicate that the unit is now ready to start receiving data. RCA and XLR connectors are available on
the rear panel to connect the unit to your amplifier.
Selecting USB Mode
Connect the USB Cable supplied with your unit to your source computer and to the rear panel of your
VERITAS unit. If your computer is a Windows based system you will need to download the Thesycon
driver from our web site before moving on from this point. VERITAS is a USB Audio 2.0 device. If your
source computer is a Mac or Linux based unit there is no need to download a driver of any type.
Select USB mode on the VERITAS unit using either the Apple remote or the rotary dial. The unit is now
ready to accept music files from your computer.
Figure 2
USB mode differs from the other digital input
modes in that volume control commands are
coordinated with the computer, specifically,

Toslink ata Receive mode (TORX)
Connect VERITAS to your Toslink device via an optical cable. Select 'T RX' input via the remote or by
cycling through the input options via the rotary dial.
AES, RCA 1, RCA2 Input options
Follow the same steps that you took when selecting USB and Toslink modes described above.
igital Filters
There are seven filter options available to choose from
when playing 44.1kHz or 44.8kHz music files. Changing
filters mode allows you to select a listening experience
most suited to your system and music content.
The filter options are listed here, and Figure 2 describes
how to change filter settings.
