1. Introduction
The Espedeo™DAC Series offers five Digital-to-Analog Audio Converters models [DAC-28xx, where ‘xx’
represents the number of analog output channels, that is 08 /12 /16 /24 /32] designed to interface with the
GDC SR-1000 Integrated Media Block™and the Espedeo Supra-5000 RGB+ Laser Phosphor Cinema
Projector. Each model supports the specified number of AES3 digital audio inputs through RJ-45 socket(s)
and the outputs are accessible via Phoenix connectors.
The Espedeo DAC Series’ front panel LED indicators show signal presence on each AES3 pair, providing an
audio interface solution for your entertainment needs.
For details regarding the usage of the DAC Series Digital-to-Analog Audio Converter with the GDC SR-1000 or
the Espedeo Supra-5000, please refer to the product documentation on the GDC or Espedeo website.

6. Regulatory Information
FCC COMPLIANCE STATEMENT
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference and (2) this device must accept any interference received,
including interference that may cause undesired operation.
CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
NOTE:This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
▪Reorient or relocate the receiving antenna.
▪Increase the separation between the equipment and receiver.
▪Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
▪Consult the dealer or an experienced radio/TV technician for help.

9. Installation and Panel Description
9.1 Installation
The DAC-28xx Digital-to-Analog Audio Converter is a 1U Rack device and can most conveniently be
installed in the amplifier rack it connects to.
NOTE:Instead of connecting the DAC-28xx to the power grid directly, it is recommended to plug the device’s
mains connection to a UPS outlet.
9.2 AC Mains Supply
The AC Main connection is made via the IEC C13 connector.
The DC series amplifiers have an automatic power factor correction system - PFC - for a perfect mains
network interface. The PFC minimizes the reactive power reflected on the network and reduces the harmonic
distortion on voltage/current waveform: in this way the amplifier is seen as a resistive load from the mains
network. Furthermore, the system allows performance to be maintained even in case of varying mains voltage.
