SPLITERS


SB SPLIT 6


Click here for full sized picture
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.

Please call 1-800-816-4262 For Pricing.


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.

Ideal for splitting and isolating mic level sends to a video truck or a 
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 is the mic splitter box to use when the widest frequency response and lowest noise are a must.

The SPLITTER-L utilizes the Lundahl LL1581XL mic transformer - the same transformer used in our very best Custom Shop Super Concert splitters. The SPLITTER-L provides one direct and two transformer isolated outputs from one mic level input.

The isolated outputs feature a ground lift button and a 20dB input pad button is provided to reduce hot signals.


CMRR @ 20kHz: greater than 60dB
Frequency Response: 10Hz-100kHz ±.5dB

Model # - SP1X3LUNT


As single-channel versions of the Multisplit 1X2 and 1X3,
the Imp 1X2 and 1X3 provide one direct and one or two
transformer isolated outputs, respectively, from a
mic level input. The Imp Splitter 1X2 provides one
direct and one isolated output, while the Imp Splitter 1X3
provides one direct and two isolated outputs.
Each transformer isolated output on
these devices features a ground lift switch.

Input Impedance: 150 Ohms 

Output Impedance: 150 Ohms

LINE BALANCER/SPLITTER

LINE BALANCER/SPLITTER LBS $83.00

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. 


Input Impedance: 600 Ohms Output Impedance: 600 Ohms (ISO mode) or 150 Ohms x 2 (Split mode) Operating Level: Input: -10dBm to +26dBm Output: -10dBu to +26dBu (ISO mode),-16dBu to +20dBu (Split mode) Frequency Response: 20Hz-20kHz ±1dB

long cable runs.

Each channel features:

  • XLR or 1/4" input
  • Ground-lift button
  • Polarity reverse button (Channel 2 only)
  • Whirlwind's own TRSP-600 transformers ensure flat frequency response and low distortion.

HEADPHONE BREAKOUT BOX $73.69


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.
