A/DA GCS-6 Manuel utilisateur

ADA GCS-6 STEREO GUITAR CABINET SIMULATOR / DI USER GUIDE

The GCS-6 is a Stereo/Dual Mono Direct Injection (DI) box with two independent, user adjustable guitar cabinet simulations, an auxiliary input with level control and two

headphone outputs, designed for the studio, stage and silent practice. The GCS-6 is an all-analog circuit that uses a 12-volt AC adapter or a pedal board power supply at

150mA or more.

•Turn two full-range passive or powered monitor speakers or sound system into two dynamic guitar cabinets

•Record directly from your pedal board without speakers or microphones or use one of the (2) HEADPHONE OUTPUTS for silent practice

•Get guitar cabinet feedback from your stage monitor

•Connect directly to the outputs of your power amp by inserting the GCS-6 between the power amp outputs and your speaker cabinets or load box

•Two full frequency range DI boxes in FULL RANGE mode

•Two independent cabinet simulations in one enclosure

•Real cabinet resonance at all levels and driver compression at high levels adds an organic depth and realism to your guitar tone

•Play along to recorded material using the AUX IN with level control

CONTROLS

▪Selectable INPUT switch for Stereo or Dual Mono routing.

▪Selectable VINTAGE (alnico) or MODERN (ceramic) speaker character. We have focused two speakers, alnico (Jensen) and ceramic (Celestion and Eminence)

▪Selectable AMERICAN or BRITISH speaker cone types for high-mid coloration

▪Selectable SEALED or OPEN BACK cabinet types to emphasize the cabinet’s natural resonance between low and mid frequencies

▪Selectable 12” or 10” speaker size

▪Two variable MICROPHONE PLACEMENT controls to “position” the mic at the EDGE for deep or CENTER for bright frequency responses

▪¼” phone jacks INPUT A and INPUT B with two direct, un-buffered PASS THROUGH ¼” phone jacks. This effectively splits the signal to feed both a guitar

amplifier and a mixing console or for connecting a speaker cabinet or load box

▪POWER AMP DIRECT CONNECT with two 20dB INPUT PADS, allows for inserting the GCS-6 between a power amp output and speaker cabinet or load box.

▪Balanced OUTPUTS with selectable LINE/MIC LEVEL with a GROUND LIFT switch for Pin 1

▪¼” phone and 3.5mm HEADPHONE OUTPUTS with a VOLUME control for 16 to 300 Ohms.

▪CABINET SELECT switch allows for Stereo, Dual Mono or Mono monitoring

▪3.5mm AUX IN jack for connecting auxiliary devices. The AUX LEVEL adjusts the volume of the simulated signal that is sent to the HEADPHONE outputs

▪CAB SIM LEVEL control adjusts the volume of the simulated signal that is sent to the HEADPHONE outputs

HOOK-UP

We do not recommend plugging your guitar directly into the INPUTS of the GCS-6 without first plugging into an effects pedal or buffer. The GCS-6 accepts signal levels from

pedal boards (guitar level) and preamp outputs (line level) or (with the INPUT PADS switched “IN” to 20dB PAD), power amp levels. Please note that the GCS-6 is NOT A

LOAD BOX and the power amplifier must remain connected to the speakers or have a proper impedance load connected to it in place of the speakers. Preamp, line level

and pedal board level signals can also be connected to the INPUTS of the GCS-6 when the 20dB INPUT PADS are switched out. The GCS-6 HEADPHONE outputs and

AUX IN have independent level controls so you can listen to the cabinet simulation and play along to recorded material in total isolation. Be sure to USE ONLY STEREO

HEADPHONES rated between 16 and 300 ohms impedance to ensure proper performance.

USING THE BALANCED OUTPUTS

The GCS-6 has both single-ended ¼-inch phone jacks and balanced XLR OUTPUTS, and both work simultaneously. For most sound systems, the XLR balanced outputs are

preferred because it avoids common audio problems such as ground loops, signal bleed and degradation. The GROUND LIFT switches are used to isolate the signal ground

of your equipment coming into the GCS-6 from the signal fed to the console. This avoids line frequency hum in your audio signal. The XLR balanced outputs can be set at

LINE or MIC level and the shields from the XLR cables are connected to the GCS-6 enclosure.

TECHNICAL SUPPORT

1. What are some quick tests to troubleshoot my unit?

Sometimes a few quick tests at home can be the difference between thinking your unit is broken and getting it working properly. Here is a list of quick trouble-shooting steps to

test your gear and unit. As basic as these appear please run all the tests.

▪Check signal chain: Plug your cable from your guitar into your amp. If you have direct-connect tone go to step 2. If not, you have a bad cable, guitar or amp.

▪Check 2nd cable: Take your 2nd cable and switch it with the first cable. If you have sound, you now know both cables, your guitar and amp, work.

▪Check power: Plug your amp into the same outlet that you’re using to power your ADA product. If the amp turns on, then the outlet works. If not try another outlet

to power your unit.

▪Check native ADA Signal Chain: Plug the first cable from your guitar into your ADA product (input). Plug the 2nd cable between your ADA product (output) and

into your amp. Make sure the ADA product is plugged into a working power source. DO NOT insert it in a pedal chain, i.e., do not introduce any other pedals into

the signal chain. If your ADA product works, your pedal chain most likely has a problem. If you hear nothing, then their may be a problem with your individual unit

2. What do I do if my product is not working?

If your product is not working we STRONGLY suggest that you run a series of quick tests to troubleshoot the unit (see above). They may appear very basic, but it can save

you time getting your unit to work and you back to playing. If you are an international (non-USA) customer, you must contact your local dealer and/or your national distributor

for repair. If you are in the USA and the unit truly does not work, email support@adaamps.com to get a Return Authorization (RA) number from us.

3. What do I do after receiving my RA number?

You will need to box your unit, write your Return Authorization (RA) number on the outside of the shipping box in a large bold lettering, and send it to the address supplied with

the RA you received from us. You are responsible for shipping to and from ADA, so please track and insure your parcels. ADA cannot be held responsible for parcels that

are lost or damaged in the shipping process. ADA cannot accept your shipment if there is no RA number written on the outside of the box.

SERVICE

If your unit requires service, please go to our website’s SERVICE page for information to help you find a solution to the problem you are having with your GCS-6. We have

provided you with a step-by-step troubleshooting procedure to get you back up and running if you are experiencing a simple problem.

RETURNING UNITS FOR SERVICE

If you need to send in your ADA product for service, YOU MUST FIRST GET A RETURN AUTHORIZATION NUMBER (RA) BEFORE YOU SHIP TO OUR SERVICE

CENTER. Items shipped to us without an RA, will not be accepted by our Service Center and will be returned to you by the shipper. You can get an RA number by first

contacting us online at: www.adaamps.com/service . DO NOT SHIP YOUR GCS-6 TO OUR SERVICE CENTER BEFORE GETTING AN RA (Return Authorization

Number) FROM US.
