INTRODUCTION
The AVC-64 is a high quality multimedia Presentation Matrix Switcher, incorporating a 6 x 4
video switcher, 6 x 4 stereo audio switcher, 2 x 1 USB switcher and an audio amplifier housed in
a tough and compact 1RU rack mountable metal enclosure. With its unique feature set the AVC-
64 has been specifically designed for the classroom, where an ‘all-in-one box’ might be desired.
An example of a typical set up may include inputs from several computers, as well as composite
and s-video connections from DVD and VHS players, all being routed to several monitors, a
projector and stereo speakers
At the heart of the unit is a 4 x 4 VGA/XGA matrix switcher suitable for switching laptops,
monitor outputs and video devices. However, the AVC-64 offers the ability for an additional
two-stage selectable) component/composite/s-video input to be routed to any one of the
switchers 4 outputs; effectively making the unit a 6 x 4 matrix switcher with support for a
projector. No need to worry about the input format, as the switcher transcodes the signal to be
projector-friendly. The two-stage selectable control stated above refers to first selecting the input
and then selecting the output format; either component or RGsB selected via DIP switch – See
page 8 for details). This extra set of inputs is extremely useful for the classroom, as it allows any
industry-standard video projector to be connected to a range of sources, allowing complete
flexibility for the demonstrator.
In addition to the above video switching capabilities offered, the unit also features a 6 x 4 stereo
audio matrix switcher and a 2 x 1 USB switcher that functions independently from the video
switcher. The stereo audio switcher features both line level and speaker level outputs, utilising a
15 Watt stereo speaker amplifier for the latter. Connected via twin RCA for the three line level
outputs, and 4 pin detachable connector for the amplified output so that it may be connected
straight to a set of front speakers), the AVC-64 unit is very capable at managing your audio
needs. The USB switcher is software selectable and is suitable for classroom whiteboards and
other peripheral devices.
The AVC-64 can be controlled via serial RS-232 connection or via TCP/IP with minimal
configuration. TCP/IP Configuration allows the AVC-64 to be plugged into an existing network,
allowing it to be easily controlled from remote locations. The unit also offers a test pattern
diagnostic function on the s-video/composite video input to aid in installation and
troubleshooting. These functions can be enabled/disabled via DIP switch settings on rear panel.
For precise control of audio, the AVC-64 provides independent audio channel attenuation
adjustment in 0.5dB steps for all audio outputs.

FEATURES
3-in-1 switcher with inbuilt audio speaker amplifier: VGA switcher, transcodes composite
and s-video signals to either component video or RGsB video for video projection, and a 2
x 1 USB switcher
Video Inputs and Outputs: 6 x 4 video matrix switcher comprised of 4 VGA or derivatives
such as SVGA, UXGA, RGBS, RGsB, and RGBHV) inputs and 4 outputs via 15-pin HD
female connectors VGA/XGA, RGB 50Hz or Component), 1 component video Y Pb Pr)
input, and 1 S-Video PAL, NTSC, or SECAM) input/1 Composite video PAL, NTSC, or
SECAM) input
VGA/XGA Bandwidth: 350Mhz
S-Video and Composite Video Bandwidth: 100Mhz
Main Audio Inputs and Outputs: 6 x 4 audio matrix switcher. 6 stereo audio inputs RCA),
1 stereo speaker output RCA) via inbuilt 15W Stereo amp, 3 stereo audio line outputs
RCA)
Volume control: 4 independent) channel volume controls; 3 for line audio outputs, 1 for
speaker audio output
USB Inputs and Outputs: 2 x 1 USB switcher with DIP switch selectable AUTO/MANUAL
mode. AUTO mode ensures input 1 is routed to the output by default, however if a signal
is detected on input 2 it will override this and input 2 will be routed to the output instead.
MANUAL mode allows for complete control
Control: software controlled via serial RS232 or TCP/IP cat5) with a DIP switch selectable
baud rate 9600 / 38400). TCP/IP MAC addressable
Test pattern program available on s-video / composite video inputs, enable / disable via

POWER ON SEQUENCE
At power on, the DIP Switch settings are loaded into the microprocessor. These
settings, along with the Software version, are displayed momentarily on the
LCD display for confirmation and ease of programming. After this, the standard
display is shown.
DISP AY
The primary function of the LCD display is to inform the user of which input is
being routed to the listed output channel. It also displays information about
transcoding, input 6 source selection and USB mode. The legend for this is as
follows:
S, C or Y: S-Video, Composite or Component Video currently being transcoded
Y or R: The transcoder is outputting Component or RgsB format
M or A: The USB mode is set to Manual/Auto
‘Video output’ and 'Audio Output' sections displays the number
corresponding to input number 1-6 ) above the video/audio output channel.
‘Volume’ section displays the volume level of all audio outputs 1 - 4), in 0.5dB
steps
‘USB’ displays the input number 1 or 2) currently being routed to the output.
