To g gle t h e SYN C LED. ( Syn c hro niz es the Pri m ar y and Se c -
ondary switches when lit).
e Dual Switch Design of the MAS7.1
With the SYNC LED lit, the MAS7.1 is simply a Multi-channel 7.1 Au-
dio/Digital Audio/HDMI switch. Pressing either '1'-'3' or 'S1'-'S3' will
select between the three inputs.
Wh en the S YNC L E D is un l it, t h e MA S 7.1 o p era tes a s t wo i n dep e n-
dent switches. A Primary switch (buttons '1'-'3') and a Secondary
switch (buttons 'S1'-'S3). Or you can think of the Secondary switch
as a v er y easy t o use a u dio b rea k a way fea tur e.
When the SYNC LED is off, pressing a Primary button ('1'-'3'), will
switch only the 5.1 Multi-channel audio paths (LF,RF,SUB,CEN,LR
& RR), while pressing a Secondary button ('S1'-'S3) will switch the
St ere o Au d io pa t hs (L & R ) , the D i gi t al au d io, and t h e HDM I s ign al.
However this default behavior can be easily changed.
For i n sta n ce if you would p refer t h e Pr i mar y sw i tch to co ntrol all
7.1 Analog Audio channels, while allowing the Secondary switch to
control the remaining channels, this is easily done.
The Primary and Secondary switches are easily configured to switch
any combination of the 5.1 Analog Audio, Stereo Analog Audio,
Digital Audio, and HDMI. See the section on "P ri m ar y / S ec on d ar y
Mappings".
Even the split between Multi-channel 5.1 and Stereo Analog Audio
channels can be changed by using a simple serial port command.
For more information on changing the Analog Audio split, download
th e "MAS7.1 Supplemental Manual".

Front panel LED sequencing while learning
During the learning process, as each button of the remote is
pr ess e d, t h e fro nt pa nel LE Ds wil l sequ ence. At a ny g ive n tim e, th e
LED that is slowly flashing, indicates the function the MAS7.1 is cur-
rently waiting to learn. The sequence is:
Standby LED Wai ting for Power To ggl e I R cod e.
'1 ' - L ED Wai ting for th e '1' IR c ode.
'2 ' - L ED Wai ting for th e '2' IR c ode.
'3 ' - L ED Wai ting for th e '3' IR c ode.
'S 1 ' - LED Wai ting for th e 'S1' I R cod e.
'S 2 ' - LED Wai ting for th e 'S2' I R cod e.
'S 3 ' - LED Wai ting for th e 'S3' I R cod e.
'S YN C ' L ED Wai ting for 'S YNC ' IR co d e.
If the LEDs do not sequence, and the IR LED does not flash, when a
bu t ton i s pre ssed o n the remot e, t hen th e MAS 7.1 do es not reco g-

default behavior is to enter into the standby mode.
It is possible to change the initial power on behavior of the MAS7.1.
To change the initial power on defaults...
Step 1: Setup the MAS7.1 to your preferred power on state .

Or if you have a household with young curious fingers that likes
playing with buttons, you also have the capability of disabling the
front panel switches and only operating the MAS7.1 with a remote.
To enable / disable the front panel switches, and other control
functions...
Step 1: Enter the Setup Mode
Th e MAS 7.1 is p laced into the s etup m ode by p re s sin g a nd
holding the Power button for about 4 seconds.
Step 2: Enter the Enable / Disable control state
While in the setup mode, press 'S1' to enter the Enable/Dis-
ab l e con tro l sta te. The c u rre nt st atus w ill be d ispl aye d us-
ing the front panel LEDs.
A lit LED indicates an option is enabled, and an unlit LED
indicates disabled.
Step 3: Enable or Disable control functions
Use '1' to enable/disable the IR Sensor hardware.
Use '2' to enable/disable the IR Jack hardware.
Use '3' to enable/disable the front panel buttons.

Primary / Secondary Mapping
The MAS7.1 can be configured as a single Multi-channel Audio /
Digital Audio / HDMI switch, or it can be used as two independent
switches, by simply pressing the SYNC button.
When the SYNC LED is lit, all channels of audio and HDMI signals

can be switched independently of each other.
By default, when the SYNC LED is off, the Primary buttons (1-3) will
switch the 5.1 multi-channel audio paths, while the Secondary but-
tons (S1-S3) will switch the L & R stereo audio channels, the digital
audio channel, and the HDMI channel.

Zektor’s exclusive K.I.S.S.™ (Keep It Simple Serial™) protocol was de-

most of their careers and understand the pitfalls of a badly designed

A few features of the K.I.S.S.™ protocol are:
A simple and logically consistent command structure.
Fully bi-directional operations and can be operated in both
a Master/Slave mode (only responds when spoken to), or
in an Asynchronous mode (state changes are sent as they
occur).
All commands and responses can optionally use a checksum
or a CRC-8 checkcode to insure reliable communications.

Rear Panel IR Control
The rear panel jack labeled "IR-IN" allows the MAS7.1 to be con-
trolled by hardwired IR controllers.
To enable/disable the rear panel IR jack, see the section entitled:
"Control Functions".
The IR signal can be either modulated or unmodulated with a modu-
lation frequency ranging from 30KHz to 500KHz.

The rear panel jack labeled "IR-IN", when not being used as an IR

To enable/disable the 12V On/Off control functions, see the section
entitled: "Control Functions".
By enabling the 12V On/Off control option, the MAS7.1 will turn
itself on whenever the voltage going into the IR-IN jack goes from
LOW to HIGH, and it will turn itself off whenever the voltage goes
fr om HI G H to LO W.
The MAS7.1 only looks at transitions on the IR-IN jack. For instance if
it d e tec t s a LOW to H IGH t rans itio n it wil l turn i t sel f o n. The us er can

Features of the MAS7.1:
Fully passive analog audio switching. All analog audio switching
is done using gold-clad over silver-paladium relay contacts. There
are no active components in the audio paths, no capacitors, no
resistors, just a gold on gold relay contact.
More than just an Analog Audio switch, the MAS7.1 will also
switch Digital Audio (with auto-conversions between Coax and Op-
tical inputs) and HDMI. Separate ground planes are used for the
analog and digital paths to help eliminate cross talk between the
analog and digital signals.
Use the MAS7.1 as a Multi-channel 7.1 audio switch, or at the
press of button it can become two independent switches, where
each switch can be easily configured to independently switch
Multi-channel 5.1 audio, Stereo Audio, Digital Audio, and HDMI,
channels. It's the ultimate in audio/video breakaway!
Independently adjustable delay times for each signal type.
Unmatched control features. The MAS7.1 can be controlled using
front panel buttons, an IR remote, an opto-isolated hardwired IR
jack that accepts modulated, or unmodulated IR signals of any
polarity, an RS-232 port, and even a simple 12V On/Off voltage.
It can be taught to use a different remote control, allowing you
to have an unlimited number of MAS7.1's in the same room and
control them all separately. The RS-232 command set is one of
the easiest to use on the market and allows unprecedented control
over the MAS7.1's operations.
Adjustable front panel LED intensities. Eliminate the distraction of
glaring LEDs by having the front panel dim after a few seconds of
sitting idle. The LEDs can even be dimmed to "off".
Perfect for the professional home theater installer! The MAS7.1 is
rack mountable and comes in black or silver.
