Description

The Electro-Voice ELX-1A mixer is a com-

pact, high-performance audio mixer de-

signed for professional applications where

clean audio and reliable operation are im-

portant. Features and performance make the

ELX-1A ideally suited for broadcast and

production recording applications. The ELX-

1A can mount in a single rack space or set

on any surface. Extensive rf filtering circuitry

and shielding provide protection against rf

interference.

The block diagram is shown in Figure 1. Fig-

ure 2 shows the front and rear panels.

General Features

• Optimum circuit design provides flat

frequency response, low distortion and

low noise.

• Space-saving, compact design uses

only one rack space (1.75 in.).

• Powerable from ac line or external

dc source, with automatic switchover;

detachable line cord.

• Electro-Pulse

indicator shows power

status.

• Switchable, low-distortion 1-kHz sine-

wave oscillator facilitates level calibration.

• Ten-segment, three-color PPM LED

bargraph meter shows peak output level

and has clip indicators; can be converted

internally to VU characteristics.

• Switchable output limiter prevents

clipping; yellow LED lights when

limiting action occurs.

Input Section Features

• A single 3-pin XLR-type connector ac-

cepts microphone and line-level inputs

via a mic/line switch.

• Circuitry incorporates rf filters and a bal-

anced transformerless design for low dis-

tortion and high signal quality.

• Switchable 30-volt phantom power is

available at microphone inputs.

• Input controls set gain of preamps for

optimum noise performance with any

input signal.

• LED indicator at each input lights if c

lipping occurs.

• Low-cut filters switchable at each input

reduce low-frequency microphone

handling and background noise.

output section features

• Transformer-isolated output with binding

posts.

• Transformer-isolated output with 3-pin

XLR-type connector and mic/line level-

select switch.

• Headphone output, with separate power

amp and level control, can drive any head-

phones or cue speaker.

• Auxiliary input jack is for fifth input or

for stacking additional mixers.

• Two stacking jacks are for interconnec-

tion with additional mixers, and can be

modified for insert patching.

Connections

• All mic/line inputs have female 3-pin

XLR-type connectors. Pin 2 is positive;

pin 3 is negative.

• The transformer-isolated outputs have a

male 3-pin XLR-type connector and dual

binding posts.

• The headphone output is a three-conduc-

tor

-inch phone jack.

• All other connections on the mixer are
