DESCRIPTION
INTRODUCTION
The Q1601 and Q1602 are small routing switchers ideal for monitoring and emergency
switching applications. The Q1601 is 16x1 and the Q1602 16x2; versions are available
for both sizes to cover most signal formats including combined video and audio routers in
the same 1U frame.
The Q1602 model has an internal mains/line power supply (PSU). The Q1602E uses one
or two external power ‘bricks’ (PSU’s) to convert mains/line voltages to low voltage DC
and this allows the Q1602E series to support a backup PSU.
All models are available as a high definition, serial video, or analogue video base model
complete with a main video module, a single power supply, and a standard controller.
Options include an audio module, backup PSU (Q1602E only), passive local or remote
panel, and a separate
Advanced Controller
module, which offers more control
functionality.
Units may be stacked together so that for instance three video units could be used to
provide a component analogue video router. This application is called
Stack Mode
.
With the standard controller, a local control panel may be attached in place of the blank
front panel or a passive remote panel connected to the rear of the unit.
With the
Advanced Controller
option installed the full range of control features of the
larger Quartz routers become available. The most obvious benefit of this option is that
any of the standard Quartz remote control panels can be connected to the router via the
Q-Link.
Another major benefit of the
Advanced Controller
is that several routers can be combined
to appear and operate like a single router with a large number of inputs. This application
is called
Cascade Mode
.
ANALOGUE VIDEO
A single main module is fitted to the base of the chassis. The video and control
connectors are of the right-angle variety and protrude through apertures in the rear of the
chassis for cabling.
The video inputs are terminated in 75
Ω
and dc coupled, enabling it to handle composite or
component signals. The output amplifiers are adjustment-free with a bandwidth to over
100MHz. In the 16x1 model there are four output feeds but in the 16x2 model there are
twin output feeds of the signal.
Switching occurs during the vertical blanking interval of the signal on Input 1.
SERIAL VIDEO (SD)
The matrix is capable of handling signals in the following formats:
143Mb/s
D2
NTSC
composite
177Mb/s
D2
PAL
composite
270Mb/s
D1
component
360Mb/s
future wide screen applications
The serial video inputs are terminated in 75
Ω
and fed to an input receiver circuit that
provides equalisation for losses, mainly at high frequencies, to serial video signals that
have travelled down long cables. This equalisation varies automatically to suit the length
and type of video cable used. The output stage re-clocks the signal from the crosspoint
so that the correct pulse widths and timings are regenerated. It automatically selects the
correct sample rates from those mentioned above. The output amplifiers are designed to
drive 75
Ω
video cables. Output 1 has twin feeds but the second output has just one feed
of the signal.
