Electro-Voice RE90L Bedienungsanleitung

Description and Applications

The Electro-Voice RE90L is an omnidirec-

tional back-electret condenser lavalier micro-

phone designed for the Architectural Series

Microphone line. The RE90L is intended for

sound reinforcement applications such as

houses of worship, schools, or other venues

where full-range, natural, well-balanced

sound is required. The omnidirectional po-

larcharacteristicsoftheRE90Lprovideclean

and accurate sonic quality and uniform out-

put regardless of the microphone's position

relative to the sound source.

TheRE90Lisdesignedtoattachtothetalker's

clothing using the supplied clips. The elec-

tronics housing features a side clip to facili-

tate attachment to a belt or pocket. In addi-

tion,the extremely compact size ofthe RE90L

is ideal for performance or house of worship

applications where the microphone must re-

mainas inconspicuous as possible tothe view-

ing audience.

Powering the RE90L

The RE90L is powered by an external 9- to

52- volt phantom power supply. The elec-

tronics circuitry is wrapped with an insulated

copperfoilfor superior emi/rfi shielding. The

module is enclosed in a high-strength poly-

carbonateresin housing to forma package that

isvery light-weight and extremely durable for

outstanding reliability and long life.

Operation

To operate the RE90L use high-quality bal-

anced cable with 3-pin XLR-type connectors

to connect the electronics housing to the

mixer input which is providing the phantom

power. The connecting cable used should be

standard two-conductor shielded type; the

shield is used as ground return and must be

properly connected to avoid electrical noise.

Microphone Placement and Cord

Looping

Typical microphone placement is shown in

the illustration. For best results, the RE90L

should be positioned as close to the mouth as

possible. It is important to loop the cable

as shown to eliminate cable rustling noise.

Windscreen

Use the external windscreen to prevent wind

and pop noise.
