Whirlwind AS8X4 microphone splitting system provides a new level of
versatility for systems requiring
5-way
mic splitting for as few as 8 or as many as 64 channels.
This system is based on rack mount modules, each having the capability of
splitting 8 mic channels to 1 direct (passive) and 4 active destinations.
A pair of high quality Lundahl transformers (Sweden) on each channel provide
superior noise rejection and balancing, making this unit the ideal choice in
applications where extremely long cable runs are required.
Each channel features switches for engaging a 20dB input pad, 48V
phantom power and for placing the channel into "listen" mode which adds it to a headphone monitoring buss.
A three step LED monitors available headroom.
Four power supplies are available, configured with the appropriate Wattage for the number of AS8X4 units required. The AS8P4 and AS8P6 include the audio monitoring electronics, the AS8P10 is two-piece with a 2 RU rack enclosure for the audio monitoring and a separate 8 RU rack enclosure containing the PSU.
All connections are made via Phoenix terminal strips for easy, solderless, on site termination. Dip switches are provided for each channel which set ground lift status and provide 10dB or 20dB of gain boost per channel. An additional 20dB of output boost can be switched in for each pair of channels.
Use this handy box when you need to split a line level* signal up to 6 times.
Features 1 female XLR input wired to 6 male XLR outputs.
Perfect when adding extra amplifiers to a system, connecting multiple powered
speakers, splitting intercom lines, etc.
* Line level outputs can usually be split 6 times without noticeable loss of signal quality.
The actual number of splits that can be accomplished depends on the level of the
source signal and the impedances of the source and destinations in a particular application.
It is not recommended that the SPLIT 6 be used to split a microphone level signal to more
than two or three outputs. Attempting to do so may result in poor frequency response and
reduced signal level. The SPLIT 6 may be used to split microphone level signals in most
applications if this limit is observed.
Whirlwind SB Series multichannel microphone splitters provide a convenient
method of splitting multiple microphone signals to two locations each.
Each channel has a Whirlwind WC3F female XLR input connector wired
to two Whirlwind WC3M male XLR outputs. These splitters are available
with either two direct outputs, one direct and one transformer isolated
output, or with two transformer isolated outputs. The splitter can be
ordered with ground lifts on one or both outputs. The boxes are built from
heavy cold-rolled steel for long term abuse-resistance.

remote broadcast, the 1U Multisplit 1X2 and 1X3 provide one
direct and one or two transformer isolated outputs per channel
respectively. Each isolated output has a front panel ground lift
switch. The inputs (female XLR) are located on the front panel and
outputs (male XLR) are located on the rear panel.
SPCON CONTRACTOR SPLITTER
Please call 1-800-816-4262 For Pricing.
Contractors working with fixed installations regularly face having to
install an organized, easy-to-maintain junction area where multiple
microphone lines come together and are split out to feed other areas.
The SPCON provides a quality, low-cost, versatile solution in a
standard 5U rack package with removable cover. Incoming mic lines
along with direct and transformer split outputs are rapidly and
reliably terminated to Eurostyle screw terminals mounted on circuit
cards. Each card provides circuitry for six channels, and each SPCON
accommodates up to four cards. This time-saving terminal design
requires no soldering or tinning of the conductors and makes field
installation a snap with just a stripping tool and screwdriver.
Outputs include one direct and either one or two transformer
isolated splits. The entirely passive circuitry requires no power
source. A phantom power option includes the extra circuitry required
for connecting the SPCON to an external phantom power supply,
such as the Whirlwind PS48. Select "YP" option. In addition, the
phantom power option can be ordered with DC blocking circuitry
installed. This option prevents the phantom power voltage from
appearing at the direct outputs where it might interact with sensitive
direct-coupled mic preamps or with patch bay systems. Select "YPD"
option.

This handy tool lets you send a line level signal to two destinations with
transformer balancing and isolation for one or both of the outputs. The
balancing provides superior noise rejection when you have equipment
with unbalanced outputs that need to feed equipment with balanced
inputs. The transformer isolation eliminates unwanted hum and buzz
caused by power line and grounding issues. In ISO mode the signal is
passed directly through the unit to one output and transformer isolated
to the second output. In Split mode the signal is transformer isolated to
both outputs, with a resulting 6dB drop in level at each output. A ground
lift switch is provided for each output. Both a female XLR and a 1/4" TRS
jack are provided for the input signal. Male XLR connectors are used for
output signals.

Sometimes you won't have a separate amp channel available for every
headphone you need to drive. Our passive headphone breakout box
divides a standard power amplifier output to feed 6 separate headphone
outputs. A resistor divider network protects your amp and helps
compensate for differences in brands and models of headphones.
Multiple boxes can be daisy-chained together with Whirlwind ST Series
cables if more outputs are needed.

supply that can deliver up to 500mA.
SPC82 SPC83
RACK MOUNT SPLITTER
(Front view, SPC83)
The Whirlwind SPC8x series of passive microphone splitters are the ideal, expandable solution for permanent installations.
Each unit provides 8 channels of mic level splitting circuitry in a single rack space unit. Depth is 7.5" including tie bar.
The SPC82 and SPC82P provide one direct and one transformer isolated output per channel, the SPC83 and SPC83P provide one direct and two isolated outputs per channel. Whirlwind transformers are used throughout. They are available with Jensen transformers, add "JT" to the model number. SPC83 and SPC83P are available with premium Lundahl transformers, add "LUNT" to the model number.
Units are also available in line level versions SPC82L and SPC83L.
The SPC82P and SPC83P feature rear terminal connections for injecting phantom power at the splitter with the optional Whirlwind DCSP1 (replaces PS48) external phantom power supply. Phantom power is blocked from the splitter's outputs, including the direct out.
Therefore, with the "P" versions, PHANTOM POWER WILL NOT PASS THROUGH THE SPLITTER FROM YOUR MIXING CONSOLE. Use the SPC82 or SPC83 model when you will be providing phantom power from the mixing console and NOT from an external power supply.
A loop through feature on the phantom connection allows a single DCSP1 to provide phantom power to multiple units, limited only by total current draw of up to 500mA.
