Hardware
The Barix EXSTREAMER 1000 consists of a motherboard with connectors and peripheral circuits supporting
the embedded IP audio module “IPAM 100”.
In this chapter we will explain the functional blocks using the below block diagram starting on the top left
and working down each interface to the point where it is connected to the IP audio module. We then do the
same from the top right corner.
For the pinout of connectors J1 to J8 please refer to next chapter “Connectors”.
The connector J4 is a DSub 9pin male connected trough a standard RS-232 serial interface transceiver with
the IP Audio module.
The connector J6 consist of a socket and a detachable 4 pin screw terminal block plug and is connected
trough a standard RS-485 serial interface transceiver with the IP Audio module.
The connector J3 is a DSub 9pin female connected trough a transformer and an I2S to AES converter circuit
to the Digital Audio output of the IP Audio module.
The AES/EBU input signal is first converted to an I2S signal and then fed through the signal source selection
block, converted to a S/PDIF signal and fed into the IP Audio Module.
The connector J2 is a DSub 9pin female connected trough a balanced line receiver circuit to the IP Audio
Modules analog stereo inputs as well as to the additional Analog to Digital converter (ADC). The IP Audio
Modules analog stereo output signals are connected to J2 over balanced line drivers.
The Barix EXSTREAMER 1000 houses the Barix IP audio module “IPAM 100” which is used for decoding all
sample rates. For the audio conversion at 32 and 48 kHz sampling rates an external, professional grade
