Frequently Asked Questions - ProSplit ART

What is the ART ProSplit?

The ART ProSplit is a passive microphone splitter that provides one direct output and one transformer-isolated output from a single microphone input.

Does the ProSplit pass phantom power?

Yes, the direct output passes phantom power from the main mixer to the microphone, allowing use with condenser microphones.

What is the ground lift switch for?

The ground lift switch on the isolated output can reduce noise due to ground loops between connected equipment. Set to Lift or GND for the lowest noise performance.

Can I use a line-level signal with the ProSplit?

Yes, the input pad switch attenuates the input for line-level signals. Engage the pad when connecting a preamplified (line-level) source to the microphone input.

What are the output connectors?

The ProSplit has two XLR male outputs: one direct and one transformer isolated. The input is an XLR female.

How do I connect the ProSplit for typical use?

Connect a microphone to the input, the direct output to the main mixer (with phantom power if needed), and the isolated output to a monitor or recording mixer. Adjust the ground lift switch as needed.

What is the frequency response of the ProSplit?

The frequency response is 20 Hz to 20 kHz, ±0.25 dB @ -15 dBu, with -3 dB at approximately 165 Hz.

What is the maximum input level?

For 1% THD, the maximum input level is -1.4 dBu @ 20 Hz, +3.5 dBu @ 30 Hz, and +9.4 dBu @ 50 Hz.

Can I open the ProSplit to service it?

No. There are no user-serviceable parts inside. Refer any servicing to qualified technical personnel.

What is the warranty period?

ART provides a 3-year limited warranty for the original purchaser in the USA. Outside the US, contact your local distributor.

IMPORTANT SAFETY INSTRUCTION – READ FIRST

This symbol, whenever it appears, alerts you to the presence of uninsulated dangerous voltage inside enclosure-voltage that may be sufficient to constitute risk of shock.

This symbol, whenever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual.

Read Instructions: Retain safety and operating instructions for future reference. Heed all warnings printed here and on the equipment. Follow the operating instructions printed in this user guide.

Do not open: There are no user serviceable parts inside. Refer any service work to qualified technical personnel only.

Grounding: Only connect the unit to equipment with properly grounded mains power. Do not defeat the grounding and polarization means of the power cord plug of the connected equipment. Do not remove or tamper with the ground connection on the power cord of the connected equipment.

Environment: Protect from excessive dirt, dust, heat, and vibration when operating and storing. Avoid tobacco ash, drink spillage and smoke, especially that associated with smoke machines.

Handling: Protect the controls from damage during transit. Use adequate padding if you need to ship the unit. To avoid injury to yourself or damage to the equipment, take care when lifting, moving or carrying the unit.

Servicing: Refer servicing to qualified technical personnel.

Installation: Install the unit in accordance with the instructions printed in the user guide.

INTRODUCTION:

Thanks for purchasing Applied Research and Technology's PROsplit. The PROSplit provides one direct output and one transformer isolated output from a single microphone input.

Applications include sending the direct output to the main or Front-of-House mixer, with the second isolated output being sent to a monitor or recording mixer.

The direct output passes phantom power from the main mixer to the microphone for use with condenser microphones.

The PROSplit includes a ground-lift switch on the isolated output to reduce noise due to ground loops between connected equipment.

For versatility the PROSplit also features an attenuator pad switch on the input that can be used to alternately connect a preamplified (line-level) signal to the two microphone-level PROsplit outputs.

INSTALLATION and OPERATION:

Connect a low impedance dynamic or condenser microphone to the MICROPHONE INPUT on the PROSPLIT (alternately connect a line level signal to the MICROPHONE INPUT and engage the front panel INPUT PAD switch.).

Connect the DIRECT MICROPHONE OUTPUT to the mic input on main mixer (switch phantom power on at mixer if desired).

Connect the TRANSFORMER ISOLATED MICROPHONE OUTPUT to the mic input on secondary mixer or recording system.

Set GROUND switch to LIFT or GND. Use whichever setting provides lowest noise performance.
