SPLIT 6
LINE LEVEL PARALLEL SPLITTER

Click here for larger 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 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. For more information, please refer to tech article "High and Low Impedance" .
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 SERIES
MULTICHANNEL PASSIVE MIC SPLITTERS

      SB24T11G
Click here for larger picture
Whirlwind SB Series multichannel microphone splitters provide a convenient method of splitting multiple microphone signals to two locations.

Each channel has a Whirlwind WC3FQ female XLR input connector wired to two Whirlwind WC3MQ male XLR outputs - available with either two direct outputs or one direct and one transformer isolated output. These can be ordered with ground lift switches on one output.

The boxes are built from heavy cold-rolled steel for long term abuse-resistance.

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.

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. (The SPC83P-S provides convenient front panel buttons for engaing phantom power and ground lifting each iso channel.)

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

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.

Model Description

SPC83P 1-direct and 2-isolated outputs, phantom power is blocked from direct in to direct out.
SPC83L Line level version, 1-direct and 2-isolated outputs. Transformer's split secondary results in a 6 dB drop in signal at each isolated output.
SPC83JT 1-direct and 2-isolated outputs with Jensen transformer, passes phantom power from direct in to direct out.
SPC83PJT 1-direct and 2-isolated outputs with Jensen transformer, phantom power is blocked from direct in to direct out.
SPC83LUNT 1-direct and 2-isolated outputswith Lundahl transformer, passes phantom power from direct in to direct out.

DCSP1 (Replaces PS48)
PHANTOM POWER SUPPLY


The DCSP1 is a regulated low-noise 48VDC power supply that can deliver up to 500mA.

Each DCSP1 provides power for approximately 96 microphones when used with the SPC series splitters.

SPLITTER-L    (SP1X3LUNT)
PREMIUM MIC SPLITTER w/ LUNDAHL TRANSFORMER






This is 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.

A 20dB input pad button is provided to reduce hot signals and each isolated output features a ground lift button.

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

LINE BALANCER/SPLITTER



Click here for larger picture
This handy tool balances and isolates a single line level signal or 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 helps eliminate unwanted hum and buzz caused by power line and grounding issues.

In ISO mode the signal is passed directly through 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 the output signals.

Also available in a 2-channel iso/balancer unit (without splitting) for stereo applications. See the ISO-2 .


Operating Level:
    Input: -10dBm to +26dBm
   Output: -10dBm to +26dBm (ISO mode), -16dBm to +20dBm (SPLIT mode)
Frequency Response: 20Hz-20kHz ±1dB

HEADPHONE BREAKOUT BOX



Click here for larger picture
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.
