DI10A Active Direct Injection Box

DI10A
ACTIVE DIRECT INJECTION BOX

Thank you for choosing a PROEL product.
IMPORTANT: read all the safety instructions that appear at the end of this document.
All PROEL products are CE approved and designed for continuous use in professional applications.
DI Boxes perform several important functions: they are designed for impedance matching and balancing the signal of a guitar, a keyboard or any line-level output source, and for injecting directly the signal with very long connections to the XLR microphone inputs of a mixing console.
D10A is an active direct box with transformer and requires the phantom power to work.
The advantage of a transformer is the possibility to avoid any electrical connection between the sound source and the mixer. This provides two huge benefits: with no electrical path, ground loops are eliminated and the cancellation of common-mode noise, like hum, is possible.
The advantage of active instead of passive DIBOX is null insertion loss and less output hum and noise.

OPERATIONS

PAD: adds 26dB of attenuation at the INPUT with lever down.
INPUT: COMBO input that accepts both 1/4” (6.3mm) JACK or XLR male unbalanced connectors.
LINK: 1/4” (6.3mm) unbalanced JACK directly connected to COMBO input.
OUTPUT: XLR balanced output.
GND LIFT: allows to disconnect the input ground (JACK sleeve/XLR pin 1) with the output ground (XLR pin 1) with lever up.
ON: this LED is illuminated as soon as the unit is connected and the phantom power of the channel is active.

CONNECTION EXAMPLE

The following image shows a typical connection:
guitar, bass or other in strument You can connect at the INPUT any kind of acoustic guitar, electric guitar, bass guitar, keyboard, pedal output or personal computer with unbalanced jack or XLR connection (or by using connector adapters).
At the LINK connector you may connect an instrument amplifier or other personal monitor systems.
The isolated balanced XLR output is to be connected to the main mixer or to the recording system with long run connection.
IMPORTANT: the input channel the DIBOX is connected to must have the phantom power active.

IMPORTANT SAFETY INSTRUCTIONS

Watch for these symbols:

The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure, that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
Unplug this apparatus during lightning storms or when unused for long periods of time.
Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
Warning: to reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment.
To completely disconnect this apparatus from the ac mains, disconnect the power supply cord plug from the ac receptacle.
The mains plug of the power supply cord shall remain readily operable.
This apparatus contains potentially lethal voltages. To prevent electric shock or hazard, do not remove the chassis, input module or ac input covers. No user serviceable parts inside. Refer servicing to qualified service personnel.
The equipment covered by this manual are not intended for high moisture outdoor environments.
Keep this equipment out of extended or intense direct sunlight.
This equipment is easily capable of generating sound pressure levels (SPL) sufficient to cause permanent hearing damage to performers, production crew and audience members. Caution should be taken to avoid prolonged exposure to SPL in excess of 90 dB.
