Rolls Audio Computer Interface GCi404 用户手册

CONNECTION

Shown here is an example of possible input connections to the GCi404.

• If the microphone connected to the

Mic Input is a condenser micro-

phone, move the Phantom Power

jumper to the ON position.

• The guitar signal may also be

connected to a guitar preamp or

processor before being connected

to the GCi404.

• Turntables must use all three con-

nections; the Right, Left, AND the

Ground terminals are required for

proper operation.

• Standard CD players may be con-

nected to the RCA LINE INPUT in

the same manner as the Portable

CD Player.

Shown here is an example of possible output connections from the GCi404 to

your computer.

• The unit is

powered via the

included Rolls

PS27, or con-

nected to a 3-1/2”

floppy drive power

cable.

• The CD Input

connects via a

4-pin connector

to your CD Rom

drive.

• The Stereo

Output connects

directly to your

sound-card Input via a stereo Tip-Ring-Sleeve 1/8” (3.5mm) cable.

• The Line Output port uses a 4-pin header cable to connect to your sound-card

Input header connector (if available).

OPERATION

MOUNTING

Make sure the computer is off, and the AC power cord is unplugged.

Select the drive bay you wish to mount the GCi404 into.

Remember that you will have cords hanging down from

the unit, so below a CD Rom drive is recommended. Re-

move the drive bay cover and gain access to the inside of

your computer.

Place the GCi404 into the open drive bay and secure it

to the computer’s internal mounting brackets using the

enclosed mounting screws.

Connect all Power and

Output cables. Plug the

computer back into an
AC outlet, and start it up.

LEVEL ADJUSTEMENT

Connect the microphone, instrument, and line/phono

sources. If the microphone being used is a condenser

type, move the Phantom Power jumper to the ON position.

Bring up the software you will be using for recording. Set

the LINE LEVEL control to approximately 12 O’Clock.

Send a signal from the line sources (CD players, turn-

tables, cassette players etc.) first and adjust the Recording

Control levels for a maximum input signal without clipping. You may need to refer to your

operating system Help menues or owners manual for assistance in adjusting input record-

ing levels.

Once you have a desired signal level, send signals from your instrument and microphone
and adjust the Levels on the GCi404 front panel for appropriate levels.

DUCKING

NOTE: Adjustements for the Ducking function are made on the rear panel of the GCi404.

You will need access to the inside of the computer if it is mounted in a drive bay.

To automatically mute all signals under your microphone, move the DUCKING jumper to

the ON position.

Send program material such as music to the Line Inputs. Speak normally into the micro-

phone and adjust the DEPTH control until the desired amount of Line signal is heard un-

der your voice. If you want the Line signal muted completely, set the DEPTH control fully

clockwise. Set the RELEASE control for the desired amount of time taken to return the

level of Line signal back to normal after you stop speaking. When the RELEASE control is

set fully counterclockwise, the time is at its longest. As the RELEASE control is adjusted

clockwise, the release time gets shorter (faster).
