SPL MASTERBAY 2487 (01) PDF MANUAL

The MasterBay Remote Control is connected to one of the MasterBay Insert boxes via the rear DB 25 connector (a 10 m cable is included). It is powered from the respective insert box through the DB 25 wiring, so no additional power supply is needed.

Labels on the MasterBay Remote Control buttons can be changed to the user’s requirements. The covers of the buttons can be lifted to insert a new label.

1. Press Insert On to activate the signal flow through the insert box.

2. When determining a new sequence, press the New button first to clear the sequence memory. The LED display shows a “-” beside each processor button.

3. Press the Processor buttons in the desired order. At this stage, you can only add another processor to the sequence; you cannot remove a processor from the sequence. If the sequence needs to be changed at this stage, press New to start a new sequence.

4. After the first sequence is determined, press Save 1 to store the sequence.

5. To create more sequences, press New again and determine a new sequence. Press Save 2 or Save 3 to store this new sequence.

6. After a sequence is saved, the corresponding Save button(s) will illuminate to indicate a valid save.

To recall a saved processor sequence, press the respective Recall button (1, 2, or 3). The button will illuminate when active.

The Insert On switch engages the Insert Box (activating the processor chain) or switches to hard-bypass. It can also be used to bypass all processors currently in a sequence.

To exclude one or more processors from a stored (recalled) preset, press the corresponding Processor Selection button. The illumination of that button will turn off, and the processor is now hard-bypassed by relays.

The processor can be switched back into the signal path at its former position by pressing the Processor Selection button again (illumination will turn on).

It is not possible to add further processors to recalled sequences. To do this, you must determine and save a new sequence instead.

When you change a recalled sequence without saving it, this change will also apply to another recalled sequence if you recall another sequence subsequently. To avoid this, you should either save the changed sequence or press the New button before recalling the next sequence.

To clear the memory of a Save location (Save 1, 2, or 3), first press the New button, and then press the respective Save button you wish to erase. The illumination of that Save button will turn off, indicating the memory for that sequence has been cleared.

The DB25 connector connects the MasterBay Remote Control to the MasterBay insert boxes with a 1:1 pin configuration. The pin assignments are as follows:

Power supply Remote Control:

Pin 22: -17 V

Pin 11: 0 V

Pin 25: +10 Va

Data exchange:

Pin 2: RS 232 – TxD

Pin 3: RS 232 – RxD

Pin 7: RS 232 – 0V

Ground:

Pin 1: Ground

The EDAC 38 pin connectors for “Insert Send” and “Insert Return” functions utilize the following 8-channel audio pinout:

(Note: Pin name alternatives like /PP, /KK, etc., are as indicated in the source material.)

Each “From Device” and “To Device” EDAC 38 pin connector on the Dual-channel MasterBay follows a standard 8-channel pinout. The channel designation depends on the specific panel label of the connector (e.g., “From Device 1-L”, “From Device 2-R”). Typically, for stereo processors, Channel 1 of a “Left” designated EDAC would carry the left audio signal, and Channel 1 of a “Right” designated EDAC would carry the right audio signal.

The general pinout for each of the 8 physical channels on these EDAC connectors is:

(Note: Pin name alternatives like /PP, /KK, etc., are as indicated in the source material. The L1/R1 etc. designation indicates how the physical channel on the EDAC is logically used based on the connection context.)

Each “From Device” and “To Device” EDAC 38 pin connector on the Eight-channel MasterBay provides 8 channels of audio, typically corresponding to a standard 8-channel surround sound format. The pinout is as follows:

(Note: Pin name alternatives like /PP, /KK, etc., are as indicated in the source material.)
