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.
