5.3.6 USER PREFERENCES
In this menu, the user is able to adjust
KEY SPEED, BACKLIGHT AUTO-OFF, LCD
CONTRAST, Master/MIDI/RS232 mode, and
selection of dBu or VU meters.
KeySpeed: KeySpeed determines the
response time of individual keys, with a higher
number meaning faster response.
Backlighting: The Protea LCD display has
an Auto-Off option which is used to prolong the life of the fluorescent tube
within the display. When the display's backlighting turns off due to the auto-off feature, simply press any key to turn it back
on. Note: Even though the backlighting tube is off, the display remains active and can be read in sufficient lighting.
LCD contrast: LCD contrast affects viewing ability under various lighting conditions and viewing angles.
Display contrast may drift over time with extended, continuous use, due to temperature changes within the unit.
*** Master: In a Multi-unit Protea system, only one unit may act as the Master Controller. This can be a 4.24RD
remote, a 4.24G set to Master mode, or Protea System Software on a PC. A single 4.24G used by itself must be set to MIDI.
*** MIDI: MIDI is the data communication protocol between all Master and Slave Protea units. Once the Master
unit has been selected, each subsequent unit must be selected to MIDI mode via menu or switches.
*** RS-232: In systems where there is PC control using PROTEA SYSTEM SOFTWARE, RS-232 serial
communication is used to connect the PC to the first Protea unit in that system.
***
Master, MIDI, and RS232 switch/menu settings for specific products in various applications can be found in the System Configuration table on page 20.
VU/dBu: Metering mode is selectable to VU (0 VU = +4 dBu), or dBu, where 0 dBu = 0.775Vrms. In addition to
the Input/Output Meters, the Compressor-Limiter Threshold and Output level reflect the current VU/dBu status.
5.3.7 MIDI
We have selected the MIDI 1.0 communi-
cations protocol for REMOTE CONTROL, or for
using multiple Protea devices in a system. The user
does not need to fully understand the details of
MIDI unless interfacing with a third-party MIDI
controller. For technical details on using exter-
nal MIDI devices with Ashly Protea products,
see the Continuous Controller Reference Table
on page 16.
If the system has multiple units or an
external MIDI source, this menu allows MIDI CHANNEL ASSIGNMENT to a local channel, simply by scrolling
each local channel to midi channel 1-16.
MIDI DUMP is used to copy all 128 presets to another unit, specifically the next one in the MIDI chain. MIDI
DUMP takes about three seconds, and will permanently change all of the presets of the next Protea unit.
MIDI MONITOR displays the most recent MIDI message received, and is useful for system diagnostics.
