Behringer HA4700-PRO-XL

With the introduction of the POWERPLAY PRO-XL HA4700, BEHRINGER announces the successor of the popular HA4600 headphone amplifier distribution systems. The new HA4700 offers four high-power amplifiers that can now drive loads down to 8 Ohms and offers improved sound performance and comprehensive new signal routing and mixing functions, which no other headphone amplifier can match. The HA4700 is currently shipping worldwide.

Features:

• Professional, multi-purpose headphones amplifier system for stage and studio applications
• Highest sonic quality with virtually all types of headphones>8 Ohms even at maximum volume
• Four independent high-power amplifier sections provide up to four stereo mixes with individual balancing
• Each input/aux section can be separately set to capture individual demands for ''more me mixing''
• Stereo aux input for each channel allows you to mix in any instrument or sound source
• Multi-functional ST./2-CH switch on each channel allows for either stereo playback or double mono operation
• Ultra-musical high and low EQ per channel for perfect sound adaptation
• Output level control with accurate 8-digit LED output meter per channel
• Left& right mute switches for each channel allow two different mixes in mono mode
• One front and two rear 1/4'' TRS output connectors on each channel
• Direct front panel input connector for easy connection of any sound source
• Paralleled main outputs allow cascading of several headphones amplifiers
• Servo-balanced, gold-plated XLR and 1/4" TRS inputs and outputs
• Ultra low-noise 4580 operational amplifiers for outstanding audio performance
• High-quality detented ALPS® potentiometers and illuminated switches
• High-quality components and exceptionally rugged construction for long life and durability
• Toroidal transformer for lowest noise interference and highest audio quality
