V-1250x-RC INFRARED REMOTE CONTROL FEATURES
The V-1250x-RC Infrared remote control provides complete zone control through the (IR) receiver located on the back panel of the
V-1250x. Infrared control requires the use of an external IR system like the Factor Electronics IR-KIT-36/56K or the IR-KIT-100K.
Each zone provides an independent (IR) connection and each zone can be controlled separately. Once zone functions have been
setup using the (IR) remote control all zone settings ill stay the same until a ne (IR) command is made or the V-1250x is po ered
OFF.

V-1250x INSTALLATION INSTRUCTIONS
IMPORTANT: The V-1250x should be situated in a ell ventilated location or position. Do not block the vents on the sides or top of the
chassis. Proper ventilation is required for normal operation. Do not expose the unit to excessive dust and do not allo dust to build up
on the unit and block the vent holes in the chassis. Do not place the V-1250x above or belo heat-generating components such as
another audio amplifier. Be sure to leave at least 2 inches of space to the sides of the chassis ith open air flo above and belo the unit.
INSTALLATION:
1. The V-1250x can be mounted in an equipment rack using the rack kit that is included ith the V-66.
2. Al ays disconnect the AC po er cord before making any connections to the V-1250x controller.
3. Use good quality 12-14a g 2 conductor stranded copper speaker ire for all 4-8ohm speaker connections and 18a g 2 conductor
speaker ire for 70 volt speaker connections.
4. Use good quality audio cables for all input source connections and keep RCA ires as short as possible, under 25 feet.
5. We recommend the follo ing tools and supplies for installation:
- Minimum one 12VDC 1 ampere po er supply
- 7 x 3.5mm mono plugs
- 24/2a g insulated ire
- (IR) Infrared repeater kit Factor Electronics (IR-KIT-36/56K or IR-KIT-100K)
- Soldering kit
- Small slotted scre driver (all speaker, IR, status and mute 12V trigger connections require a small slotted scre driver)
IMPORTANT: All V-1250x ZONE INPUTS ARE EFAULTE TO THE BUS INPUTS AT MAX VOLUME
The V-1250x is a very versatile amplifier and can be used in multiple ays.
It's important to decide ho each channel ill be used prior to connecting
sources and speakers to the controller. Simply plugging a source into the
V-1250x and connecting speakers may not provide sound. You ill need
to activate the zone, select the correct source and adjust the volume. This
can be achieved ith an IR kit, 12VDC input or RS-232 control. It's al ays
best to decide ho you ill use the V-1250x and have the necessary tools
on hand to complete the installation. The BUS inputs are the default inputs
for each zone. Insert a source into the BUS input (either 3.5mm analog or SPDIF
Optical) and select BYPASS ON ith the remote bypass dip s itches for default
audio. NOTE: the zone volume ill be MAX for all channels until the volume is
Adjusted using external IR or RS-232 control.
IMPORTANT: BACK PANEL POWER SWITCH:
The V-1250x back panel po er s itch can be left ON constantly once all
connections are completed and verified. All V-1250x amplifiers ill automatically
enter the default OFF state if the master po er s itch is turned off. Once all the
parameters are set for each zone it's best to leave the master po er s itch ON
to retain zone settings. If the Master po er s itch is turned OFF or a po er outage
occurs, each zone ill need to be re-configured using IR/RS232 to control the zones.

V-1250x INSTALLATION INSTRUCTIONS CONNECTING SPEAKERS
IMPORTANT: O NOT USE THE 70VOLT AMPLIFIER SETTING IN BRI GE MONO MO E.
This will produce an output voltage of 140 volts which will damage the connected speakers and produce distortion.
INSTALLATION: Connecting Speakers to the V-1250x
Use a good quality stranded copper speaker ire for all speaker connections as follo s:
4-8ohm Speakers use 12-14awg stranded copper speaker ire.
70 Volt Speakers, use 16-18awg stranded copper speaker ire.
The V-1250x provides 12 independent amplifiers or 6 independent stereo amplifiers. Each amplifier pair can be set for 4-8ohm stereo
operation, 8ohm mono operation or 70 volt operation. Al ays use a minimum speaker impedance of 8ohms in BRI GE MONO operation.
Remove approximately 1/4” of insulation from the ends of the speaker ires. T ist or solder the ends of the speaker ire to insure that
small strands of adjacent ire cannot touch creating a short. Remove the green speaker output terminal block connector and turn the
set scre s fully counter clock ise to open the connector. Insert the speaker ires in the correct connector holes making sure that no
bare ire is sho ing. Tighten the set scre s by turning clock ise until the ire is crimped and cannot be pulled out. Insert the speaker
connector into the amplifier and apply a little pressure until the connector snaps in place. Repeat for all speaker connections.

IMPORTANT: THE STEREO ANALOG 3.5mm BUS INPUT WILL OVERRI E THE STEREO OPTICAL INPUT. TO USE THE STEREO
OPTICAL INPUT O NOT CONNECT TO THE ANALOG 3.5mm BUS INPUT.
The BUS INPUTS are the default inputs for all zones.
INSTALLATION: Connecting Audio Sources to the V-1250x
Use good quality RCA cables, 3.5mm stereo cables or SPDIF optical cables to connect to the V-1250x. Keep RCA cables and 3.5mm
stereo cables under 25' in length to avoid RF interference.
NOTE: Each V-1250x zone is capable of s itching bet een the RCA LINE IN or the OPTICAL/ANALOG BUS IN independently.
S itching can be achieved using an (IR) Infrared system connected to the zone IR input, zone 12VDC LINE/BUS trigger input or RS232
commands ith the V-1250x RS232 connected to a master control system. Controlling the input s itching ill be discussed in detail later
in this manual. The default input for each zone is the STEREO BUS 3.5mm stereo or SP IF optical INPUT.
1. Connect a source to the BUS input, select REMOTE BYPASS ON for the selected zone. Audio will play at MAX volume.
2. Connect a source to the LINE IN, select REMOTE BYPASS ON for the selected zone. Apply 12V C to the LINE/BUS TRIGGER
IN. Audio will play from the RCA LINE input at max volume.
3. Audio volume levels can be changed using Infrared or RS232 commands. Once a volume level is changed the V-1250x will
store the new level in memory and replay at the new volume level even if the master power switch is turned off.

V-1250x INSTALLATION INSTRUCTIONS (IR) INFRARED CONTROL (IR FREQUENCY 38kHz)
IMPORTANT: ZONES 1-6 CAN BE CONTROLLE WITH AN INFRARE REPEATER SYSTEM CONNECTE TO THE IR/GN ZONE
INPUTS. THE ZONE REMOTE BYPASS SWITCHES MUST BE SET IN THE OFF POSITION TO ACCESS INFRARE FUNCTIONS.
INSTALLATION: CONNECTING AN (IR) INFRARE REPEATER SYSTEM TO THE IR/GN INPUTS
We recommend using a high quality Infrared repeater system like the Factor Electronics IR-KIT-100K or IR-KIT-36/56K. The V-1250x
infrared operating frequency is 38kHz hich is compatible ith most North American Infrared systems. Each zone can be set up
independently. The IR settings ill be stored in memory provided the master po er s itch stays in the ON position and the po er cord is
not unplugged from the unit. Po er outages ill cause the zones to return to their OFF default state. We recommend using a separate
IR system for each zone that ill be used independently here changes to the zone ill be made on a regular basis. All zones can be
controlled using a single IR repeater system (Multizone Control) ho ever changes to the system ill be global and ill affect all connected
zones.

V-1250x INSTALLATION INSTRUCTIONS BUS IN/OUT, LIMITER & MASTER CONTROL TRIGGER IN/OUT
BUS IN/OUT: EFAULT ZONE SOURCE
The BUS IN/OUT is used to send the same input source to any of the six zones or all zones.
The BUS input can be selected by any or all channels by using the IR remote control and an external IR
system or by programing the correct RS232 codes into a maser control system connected to the RS-232 jack.
Or simply connect a source to the BUS input and select REMOTE BYPASS ON using the dip s itches.
The BUS input ill broadcast in all zones provided there is no voltage applied to the LINE/BUS trigger input.
The BUS OPTICAL input is a digital SPDIF stereo input that converts the digital signal to analog for use in the
amplifiers. The analog BUS inputs/outputs are stereo ho ever they can also be used as dual mono inputs to
feed the LEFT/RIGHT channels of any zone for 70Volt installations or any configuration that requires mono
audio. The BUS OUTPUT takes its signal from the BUS inputs OPTICAL/ANALOG BUS input jacks. The BUS
OUTPUT can be used to cascade the BUS INPUT to multiple amplifiers or po ered sub oofers.
Wiring for the Analog BUS IN/OUT using a 3.5mm stereo jack:
COMPRESSOR/LIMITER:
Each zone provides a LIMITER s itch. When the LIMITER s itch is ON the limiter ill automatically monitor
the zone input signal and lo er the level of loud audio peaks to prevent overload of the amplifier. A practical
application for the LIMITER ould be in a microphone or telephone paging setup here an operator may
speak loudly into the microphone causing amplifier overload and distortion. The limiter ill automatically
prevent the overload. Another practical use ould be music sources hich have vastly different levels here
one source is loud and another is quiet. This is very common ith smart phones and MP3 players here the
music is recorded at different levels. The LIMITER ill automatically level the sources. The V-1250x LIMITER
Is high quality and barley audible hen ON. The LIMITER is capable of providing up to -20dB of gain reduction
on peak audio signals. We recommend using the LIMITER.
MASTER CONTROL TRIGGER IN/OUT: LINE/BUS/MUTE
The V-1250x amplifiers must be individually po ered ON to operate. This can be achieved by selecting ON using
the REMOTE BYPASS dip s itches or select OFF using the REMOTE BYPASS dip s itches and connecting an
external IR system and using the V-1250x-RC remote control, or using RS-232 control and a master control system.
Here is simple ay to po er ON/OFF/MUTE all six zones:
REMOTE BYPASS ON: All zones ON the default input source is BUS.
REMOTE BYPASS ON JACK INSERTED IN MASTER TRIGGER IN (0VDC SHORT +/-): All zones MUTE.
REMOTE BYPASS ON JACK INSERTED IN MASTER TRIGGER IN 12VDC: All zones LINE INPUT
Using a simple s itch, all zones can be MUTED or the input can be changed from BUS to LINE using the
MASTER IN jack. The MASTER OUT jack provides 12VDC hen any amplifier or zone is po ered ON.
The MASTER OUT jack can be cascaded to other amplifiers, control systems or peripheral equipment like
projectors, po ered cinema screens and can be used to turn ON/OFF other equipment automatically.

Zone Activity and Zone Status:
The commands/queries for zone status:
ZA – Zone Activity Auto Update Enable Command. Format - !ZA{0/1}+
ZS – Zone Status Query. Format - ?(z#}ZS+
Zone Activity Auto Update Enable Command
The Activity Update ill cause the system to send out the complete Zone State henever
something in the zone changes. The State string ill be sent out one second after activity
in the zone stops. Also, the Metadata ill be sent out henever it changes.
Zone Status Query:
The Zone Status Query ill cause the system to send out the full Zone State string along
ith the Zone Metadata string(s), for the specified zone.
Important Note: Also, use the highest baud rate that the receiving system can support.
When the Amplifier sends out complete Zone Status, (either due to an explicit query or
due to an Auto Update, the data is formatted a bit differently than the standard responses
to a Command or Query.
All Zone Info / Zone Status output lines will begin with the character ‘#’ (the
sharp, or number sign).
The format of the Zone State is:
#{z#}ZS VO{v#} PO{0/1} MU{0/1} IS{0/1}+
An example:
#6ZS VO8 PO1 MU0 IS0+
This line tells us the follo ing info about Zone 6:
Zone Volume – 8
Po er – On
Mute – Off
Input Select – Bus
