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.

V-1250x INSTALLATION INSTRUCTIONS CONNECTING SOURCES
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 12VDC TRIGGERS
IMPORTANT: THE 12V C TRIGGER INPUTS PROVI E CONTROL OVER ZONE MUTE & LINE/BUS SOURCE
SELECTION AS FOLLOWS WITH REMOTE BYPASS ON:
1. MASTER CONTROL IN: +12VDC= all zones ON LINE INPUT/0VDC (short +/-) = all zones MUTED
2. MASTER CONTROL OUT: all zones off = 0VDC output/ any zone on = 12VDC output
3. ZONE STATUS 12V C OUT: zone on = +12VDC output / zone off = 0VDC output
4. ZONE MUTE: 0VDC= zone on (UN-muted)/+12VDC= zone muted
5. ZONE LINE/BUS: No connection= Bus input/3.5mm Jack connected 0VDC (short +/-) = Bus input /+12VDC= zone Line RCA input
6. Zone Line/Bus ry contact: (short +/-) zone s itches to BUS (note if the zone as previously in Bus this ill have no effect)
INSTALLATION: CONNECTING 12V C TO THE V-1250x LINE/BUSTRIGGER INPUTS
Use 22-28a g t o conductor ire for all 12VDC trigger connections.
Applying +12VDC to the LINE/BUS input the Line RCA source ill play / 0VDC (short +/-) the BUS source ill play.
WIRING: 3.5mm MONO plug (Tip + Sleeve GN )
INSTALLATION: CONNECTING 12V C TO THE V-1250x MUTE TRIGGER INPUTS
Use 22-28a g t o conductor ire for all 12VDC trigger connections.
Connect the ground ire to the GND terminal connector.
Connect the + positive ire to the MUTE terminal connector.
It's common practice to ire a s itch to the positive + lead of the 12VDC or to short the +/- to control trigger on/off.
Connecting the +12VDC and the ground ithout a s itch ill provide a permanent zone mute state.
Applying +12VDC to the MUTE. Zone ill be muted / 0VDC (short +/-) = zone on.
