User manual ROLLS RP93S

[. . . ] SPECIFICATIONS Jacks: MIDI ports: Display: Phantom Power: MIDI signals recocnized: Size: Power: SEND 1 RP93s RFX MIDI PHANTOM POWER Inspired by an article in the December 1989 issue of Electronic Musician (by Craig Anderton), we decided to emulate their MIDI phantom power model for RFX equipment. MIDI receivers supply 12 VDC on pins 1 and 3, and transmitters receive power on those same pins. Many MIDI devices can be modified to supply power down the cable, but of course RFX makes no warranty to anyone as to the applicability of this modification or any damage that might be done as a result thereof. We supply this note for those adventurous people who may want to give it a try. [. . . ] These may be used to control the presence of foot pedals, rack processors, other instruments, etc. These may also be used as a 4-way A/B box by connecting to the FX returns only and using the Main Out as the output. Since the RP93s is passive in its signal path (all switching is done with relays), the signal may go either way. This means the RP93s may also send a single signal to up to 4 different amplifiers. There is no change of interference or crosstalk because the switches are contact closure between the tip and sleeve of the 1/4" connectors. There is no connection between the different switches. LEARN MODE Changes to the Switch and FX Loop settings for each Program Number settings are all made and stored in Learn Mode. Setting the MIDI Channel, and utilizing the RFX MIDI Test Mode are also done in Learn Mode. ENTERING LEARN MODE · The RP93 enters Learn Mode by pressing both UP and DOWN buttons simultaneously, and holding them down for approximately 5 seconds. When in Learn Mode, the numeric desplay blinks. Please note that in Learn Mode, no MIDI data is processed by the RP93s but data will continue to pass to the MIDI Through port. MODIFYING PRESETS · Pressing the UP and DOWN buttons will increment and decrement the display of the Program Number. As in Operating Mode, changing the Program Number with the UP and DOWN buttons will cause the stored switch and FX loop settings to be engaged. · Pressing a switch or LOOP button will alternate the on or off state of the associated switch or FX loop port. Changing the state of a port in this way does not affect the programmed setting for the displayed Program Number (until the STORE button is pressed). The state of a switch or FX loop port is indicated by the LEDs. · When the desired setting is shown on the LEDs, press STORE. This will save the current setting of the switch and FX loop ports for the displayed Program Number. The display will blank momentarily during the storing operation. CHANGING THE MIDI CHANNEL In order for a Program Change commant to affect the switch and FX loop settings, the proper MIDI channel must be set. · To set the MIDI Channel, enter Learn Mode. Press the DOWN button until 01 is displayed, then press once more - an oF appres in the display. [. . . ] OUT: 1/4" TRS jack containing the signal(s) from the IN and the four FX Loop jacks. RETURN/SEND jacks 1 - 4: 1/4" TRS jacks used to send stereo signals from the IN jacks out to signal processing devices, and return them back to the OUT jacks. IN: 1/4" TRS jack for connection to the device with the signal to be processed in the FX Loop jacks. OPERATION Operating Mode The RP93s switch settings, once pre-programmed, are recalled via MIDI Program Change information and are then shown on the front panel display. [. . . ]
