Product :: 2x4 Audio Controller(Discontinued)

« View more Audio Controllers

The 2x4 Audio Controller is a compact (1 rack space), comprehensive audio switching and control system designed to interface a wide variety of effects and amplifiers. Easily configured for use with any type of system, the 2x4 can be the heart of a simple pedal-based system, to a more elaborate line level "rack effects" rig, or any combination in between. The 2x4 consists of 8 series audio routing loops and 4 "footswitch type" Control Functions, 2 of which can be used as switchable audio outputs (mutes). These 12 functions are MIDI controlled via control change numbers, and can be interfaced with a number of different control devices. Of course, the 2x4 is best suited for use with the CAE RS-10 MIDI Foot Controllers.

The RS-10MKII is a perfect companion for the 2x4 and is fitted with a rugged XLR connector, as is the 2x4, for reliable, easy interfacing. The 2x4 Audio Controller utilizes passive relay based switching in it's signal path for the utmost sonic transparency. In addition, unlike other relay based switchers, the 2x4 uses 2 separate relays for each loop; 1 for the send, and 1 for the return. This eliminates any high gain crosstalk and/or oscillations when using preamps or fuzz pedals in the loops, resulting in quieter, more predictable operation. Switching noise is also kept to a minimum. The 2x4 consists of 2 series chains (A&B) of 4 loops each. The inputs and outputs of both chains are accessible on both the front and rear panels of the 2x4, the front panel inputs having priority over the rear. The input of each chain contains a low noise signal buffer to eliminate signal loss when feeding the chains with high impedance signal sources such as passive guitars. Both buffers can be hard-wire bypassed on the front panel for a completely passive signal path. The loop sends and returns are located on the rear panel of the unit as is the MIDI In, Out/Thru and 9vac power input. The front panel also contains the Control Function jacks as well as the switchable audio outputs. In addition, there are LED's to indicate Loop/Control Function status and power. As mentioned before, the front panel also utilizes an XLR connector for interfacing CAE RS-10 MIDI Foot Controllers.
