Roll's GCi404 is an audio interface that mixes a balanced XLR microphone input with a 1/4" TS phone instrument signal and a group of stereo line input signals. The unit is sized to fit inside a drive bay of a computer-tower enclosure. Uses for the interface include commercial audio production, home audio voiceovers, phonograph record to CD recording, etc.

The microphone input provides +12 volt phantom power, a variable level control ranging from no signal to +55dB of gain and a balance control. The instrument input has a level control variable from no signal to +30dB. The line input group of the GCi404 features three types of inputs that include stereo RCA phono, 1/8" TRS phone and a stereo phono preamp with grounding post and built-in RIAA equalization. These signals are mixed at the line level control.

A ducking feature has been included in the GCi404 which, when engaged and a signal is present at the microphone, will duck the remaining input signals under the microphone signal. The ducking controls are located on the rear panel and include depth and release time controls. The depth control adjusts the level of signal reduction while the release control varies the amount of time taken for the program material to return to its previous level. Access to the inside of the computer is required if adjustment to the ducking process is needed.

The GCi404 requires 12VDC and a power supply is included, or the unit may be powered by the computer's internal drive power cable. A CD input has been included on the rear panel for connection to the computer's CD drive and the outputs on the unit are stereo RCA phono and 1/8" TRS phone as well as a 4-pin header to connect to a sound card if installed.

      Comments about Rolls GCi404 Audio Computer Interface:

      I have deployed over 250 of these in a classroom environment. We've had a few go bad, but not above the normal failure rate of equipment in large deployments. I use the phantom power in all of the rooms to power a microphone- maybe the other reviewer had bad luck or had not switched the jumper that enables the phantom power? All in all, they have been solid over the past 2 years running 24 hours a day (ours our used outside of the computer and powered by a wall wart).

      Phantom Power does not work

      Comments about Rolls GCi404 Audio Computer Interface:

      XLR works with dynamic mics, but since phantom power is not working, condenser mics will not work at all. Sent it to Rolls, and they sent it back without fixing it. Bad service. Would not buy again from Rolls. I wish another company would create an audio interface with XLR and phantom power for the CD drive bay for the PC.
