Symetrix 506E Headphone Amplifier User’s Guide

Product Summary

The 506E Headphone Amplifier contains

6 discrete headphone amplifiers, which

are normally driven by a stereo

program input. Each amplifier has an

independent level control. The PRO-

GRAM INPUT section also has a level

control and STEREO/MONO switch. The

CUE INPUT section has a level control

and Left/Center/Right ASSIGN switch.

Features

Proprietary High Voltage

Drives multiple headphones of any
impedance greater than or equal to
8 ohms with the equivalent output
voltage of a much larger power
amplifier.

6 Stereo Outputs

Automatically adjusts output power
to match the load impedance. Can
be used as a one-input, 6-output
headphone amplifier or as 6 head-
phone amplifiers.

Unique Mono Cue Input

For feeding a mix minus or IFB from
a producer or remote talent into the
main monitor mix during a live
broadcast, or for feeding a click
track during a recording session.
Assignable to left, center (left and
right), or right.

Mono/Stereo Switch

Maintains stereo signal integrity
from input to output or, in mono
position, either or both program
inputs may be used to provide mono
program signal.

Direct Input/Output and

Allows you to interrupt the program/
cue input on each amplifier channel
and to insert a separate signal to
drive that amplifier channel indepen-
dently from the other channels. Gain
controls are provided for program
and cue inputs and for the 6 output
amplifier channels.

Internal Power Supply

No “wallwart” or “lump-in-the-line.”

Optional Headphone Remote Box

Same 6 headphone outputs are also
provided at the rear panel to provide
output to the Symetrix HR-1 Head-
phone Remote.
