Behringer HA4600 Powerplay Pro
4-Channel Stereo Headphone Amplifier
• Three outputs for each channel
(one front,two rear) enable
connection of up to 12 head-
phones.
• Ultra musical 2-band EQ per
channel
• Independent input/aux sections
provide up to four stereo mixes.
• Stereo aux inputs for each chan-
nel permit the inclusion of
additional sound sources.
• Adjustable direct in on the front
panel for additional stereo sig-
nal source.
• Paralleled main outputs allow
cascading of several HA4600’s
• 8-digit LED output meters for
each channel enable precise
level control.
• Servo-balanced, gold-plated
XLR and 1⁄4˝ TRS inputs and
outputs
Fostex PH-50 Headphone Amplifier
• 5 headphone outs - each with
its own amplifier
• Each input routes to its direct
output, plus Aux 1 source (cue
feed)
• Multiple inputs: balanced XLR,
phone, unbalanced RCA jacks
• +4dBu or -10dBV switchable
for balanced inputs
• Individual level controls with
peak reading LED
• Stereo or mono input select
• Cascade inputs & outputs for
‘daisy chaining’ units
• Aux In with level control for
cue feed from main mixer
• Freq.response is 30Hz - 20kHz
The PH-50 is a
remarkably
quiet head-
phone DA
(distribution
amplifier).
Each output
has its own amplifier
as well as its own level control - so individual requirements
can be met with ease. Multiple PH-50s can also be cascaded to handle
a large number of listeners making it ideal for orchestral, multimedia,
education and trade show applications.
The PH-50 is especially handy in the studio environment because an
output from the mixer can send a talkback signal to the Aux input
(complete with level control) of the PH-50 & be distributed to all
headphone outputs. This great cue system makes for more effective
communication between engineer/producer & musicians.
Symetrix 304
This stereo input, four output amplifier
drives headphones of any impedance. Used
in broadcast, installed sound, and record-
ing applications, high voltage technology
provides 6dB volume increase over most
competing units. Compact half rack chas-
sis permits 8 channels in one rack space.
◆ Individual volume controls for each out-
put, master input volume.
◆ Stereo or mono operation, balanced or
unbalanced input.
◆ Pass Thru jacks permit daisy-chaining of
multiple units.
Shure FP-22 Headphone Amplifier
The FP-22 is a battery-powered
stereo headphone amplifier that
provides headphone feeds from any
audio input source. It has the unique
capability of monitoring mono, stereo
and mixed mono and stereo inputs.
It monitors and combines these
signals in the headphones without
affecting the original signal. With
81dB of gain, it can monitor a wide range of signal sources in many different configu-
rations. Ideal for field production, studio recording and trouble shooting applications.
◆ Loop through 1/4˝ stereo phone jacks (can
be internally switched to become separate
left and right inputs).
◆ Overall headphone balance control,overall
stereo/mono switch for headphones.
◆ Independent control of headphone
volume as well as loop-through volume
Developed for the most demanding broadcast,digital production and
professional recording applications,the HA4600 is ideal as a reference
unit to assess the quality of a final mix, and as a distribution amplifier
for the addition of playbacks in studio use. The HA4600 offers premi-
um sound quality even at maximum volume and houses four inde-
pendent high-power stereo amplifiers each with a stereo aux input,
mono/stereo and left/right mute switches, balance and volume con-
trols and more, plus numerous master features, in a single rack space.
◆ Balanced loop through XLR connectors
are mic/line switchable.A 30dB pad
attenuates loud line level sources.
◆ 1/4˝ and 3.5mm stereo jacks
◆ Powered by 9v battery or external
12-24v DC power supply.
