GKMX-42 Four Guitar/Unit Selector
" Four Guitars to Two
Synths "
GKMX-42 has an integrated Roland US-20 compatible A/B unit selector combined with the possibility to connect external VOLUME pedals for each synth unit. It also has foot switches for S1 and S2 commands to control the synth unit(s).
| Connectors | |
| GK1-GK4 | GK input connectors for up to four GK-Ready guitars |
| J1-J4 | Guitar buffered input jacks for connecting up to four standard guitars, or GK guitars with separate cable for the regular pickups, i.e. two-cable meothod. |
| GK OUT (A & B) | GK output connector for Roland GR-33, GR-55, VG-99, GR-D, GR-S or other compatible 13-pin synthesizer. |
| SEND | Connect the SEND jack directly to your amp for better harmonics and lower noise of the regular pickup sound, or connect to optional effect pedals before the regular guitar pickup signal is routed back to the synthesizer using the RECEIVE jack. |
| RECEIVE | Connect to output of your optional effect pedals, or use the hexaphonic pickup for various guitar sound emulations in the synthesizer and then connect the Guitar out or Left or Right synth output to the RECIEVE jack for further COSM processing in the synthesizer (as if the emulated guitar signal was coming direct from you guitar). |
| Guitar selection | |
| SEL FOOTSWITCH | Selects one of the input channels. This switch will cycle through the input channels when engaged. |
| 2,4,3 | 3-way switch allowing you to select the maximum number of inputs for cycling. Select 2, 3 or 4 guitars. |
| S1/S2 Synth control | |
| S1/S2 CTRL | Four-way rotory switch to select S1,S2 target: Unit A, Unit B, Both unit A and B, or the Actual Unit selected by A/B foot switch. This allows you to, for example, change synth patch of synth A using the foot switches and change patch of synth B with the guitar S1/S2 controls. |
| S1,S2 FOOTSWITCH | Sends S1 or S2 command to the unit selected by S1/S2 CTRL rotary switch. |
| Synth volume | |
| VOL A JACK | If you connect an external Roland EV-5 or compatible expression pedal you may control the volume of synth A with the pedal. |
| VOL A MAX/GTR | If the switch is in MAX position, the volume pedal operates independant of the actual volume of your guitar. In the GTR position the guitar volume is the master volume, and the volume pedal may be used to further reduce the volume of synth A. |
| VOL B JACK | Same as VOL A jack but for Unit B. |
| VOL A MAX/GTR | Same as VOL A MAX/GTR but for Unit B. |
| Power | |
| 12VDC |
The unit is powered by either synth A or B or by an external
0.8-1.5 Ampere 12 VDC adapter (not included).
If more than two 13-pin guitars are connected and you are unsure about the power consumptions we
strongly recommend using an external adapter.
If a 12VDC adapter is connected you may also use the switcher as a 4 channel standard guitar switcher (no GK, no synth) and connect the SEND jack to your amplifier. |
The 13-pin inputs are compatible with Roland GC-1 or any
other 13-pin pin GK-3, GK-2 or GK-KIT
equipped guitar.
The 13-pin output is to be connected to a guitar synthesizer, compatible with Roland
GR-55, VG-99, GR-D, GR-S
or earlier. All standard input jacks are buffered. The unit and your
guitars are powered either by the connected synth or using an external 12VDC
adapter. For standard guitars connected to one of the input jacks, only the
regular pickup signal will be available to the output synthesizer unit. This
unit does NOT convert regular pickups to MIDI. The warranty associated with this
product covers the unit itself and the GK-cable(s) within the bundle. Any
equipment connected to the unit, such as synths, guitars or other electronic
equipment whatsoever, is NOT covered by the product warranty.
