GearBox 18/6 Overview
GearBox • 18/6
-
SUMMARY - The GearBox 18/6 is a 18 input, 6 output, CobraNet Networked Automixer with a fully
integrated PoE switch. Perfect for small venues who want the advantages of networked audio without breaking
the budget. Oh yeah, it interfaces seamlessly with other Attero Tech products, as well as all other CobraNet
products.
-
INPUTS & OUTPUTS - The GearBox has 18 audio inputs. Sixteen come from any source on the
CobraNet network. Two local analog inputs accommodate legacy devices like wired or wireless mics, or other
line level analog sources. Of the six outputs, four are digital, back to the CobraNet network and two are
legacy analog outputs can provide audio to non-network devices.
-
AUTOMIXING - The GearBox features a proportional gain automixing system, which is insensitive
to changes in background noise and is completely inaudible in operation. Every multi-mic installation will
benefit by having less feedback and more intelligible audio with the GearBox Automixer on the job.
-
DSP - All inputs have gain control, filtering, full automixing, and EQ. All outputs have a
2-band fully parametric filter, gain control and an adjustable limiter. There's also a full 18x6 mixer.
-
REMOTE CONTROL - Input and output gains can easily be remotely controlled using the single-gang
wall mount RV-1 Remote Volume Control. There’s also built-in support for room combining up to 4 rooms with the
RC-4 Remote Room Combining Control. And you can also control the GearBox with third party remote controls.
GearBox • 18/6 Details
The GearBox 18/6 CobraNet Networked Automixer is a highly integrated 18 input, 6 output digital automixer with DSP. The
GearBox includes a fully managed 8-port PoE enabled Fast Ethernet switch with a Gigabit Ethernet expansion port. The GearBox
accepts up to 16 networked digital inputs from any CobraNet input source (e.g. Attero Tech InBox units), and has 2 legacy mic/
line analog inputs. Two legacy analog outputs complement 4 networked digital outputs, with a full 18x6 matrix mixer between
inputs and outputs. In-room remote control is provided by the RV-1 Remote Volume Control and the RC-4 Room Combining Controller.
Both the RV-1 and RC-4 are single gang Decora style wall plate controls powered by the GearBox.
