  • Unit Weight: 7 lb (3.2 kg)

Just because a single blue RAD port is 2 digital in and 2 digital out, the cascadeable AM1 and AM2 Automixers offer up to 64 mic inputs at a single RAD port!

 

General Description

Meet HAL, an expert in room combining, paging and distributed

audio systems. This groundbreaking architecture is dimensions

beyond any other solution. HAL easily guides even novice

users through what used to be complex tasks in just minutes.

No intricate matrix mixing or presets are required for room

combining and paging. No virtual wiring required to distribute

pages and background music to multiple zones.

Seamlessly interface HAL to your application with a broad

variety of peripheral devices including smart Digital Remotes,

Remote Audio Devices (RADs), portable and in-rack automixers,

audio I/O and control logic expansion devices, wall sensors,

ambient sensing mics, small remote amplifiers, and an advanced

Paging Station.

In addition, the HAL Multiprocessor and Halogen software

check the status, location, CAT 5 wiring integrity, and that audio

is flowing in all peripheral devices, so you know your system is

properly connected and ready to go.

HAL is more than just another DSP drag-and-drop system. It

has revolutionized system design and installation.

Three HAL multiprocessors provide various audio I/O and

control options for both large and small installations.

• HAL1 supports 16 in x 16 out audio, which may be increased

up to 80 in x 48 out by adding EXP1 Expanders. More mic

inputs can be added with AM1 and AM2 Automixers.

• HAL2 supports 18 in x 18 out audio, of which 2 x 2 come

from AES3 on XLR connections.

• HAL3 supports 4 in x 8 out audio, of which 2 “Line-Plus”

Inputs accept balanced line, or sum stereo unbalanced lines.
