SPLITERS
WHEN WILL I NEED A SPLITTER?
As your sound system expands, it will eventually be necessary to provide additional mixes from locations other than the main mix position. Although it's possible to provide a separate monitor mix from the main console, a person located nearer to the performance area can hear what the performers hear, see their cues more easily and just generally be able to provide a better monitor mix.
Or you may be called upon to provide a separate mix for recording or broadcasting your performances. That mix will be at its best if the person providing it is isolated from the confusion of hearing the live sound. In any event, you'll most likely need to split your mic signals and feed more than one mixing console.

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.

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.

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

SPC82 SPC83
RACK MOUNT SPLITTER


SPC83 Front

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.



SPC83P Rear

All connections are made via removable Phoenix style connectors - cable end connectors are included.

A set of dip switches is provided for each ISO output for lifting the ground connection between input and ISO output.

Rear tie-bar is provided for attaching cables securely to avoid accidental disconnects.
