Operating Manual - PROTEA SYSTEM II Digital Audio Products

5.12  SCENE

The SCENE function is a convenient way to save and recall the block of presets used to create the entire system

environment.  Up to 50 different scenes may be stored, with each scene capable of controlling up to sixteen local
channels.  Note:  Saving a Scene does not store the parameter details within each preset, just the currently loaded preset
numbers.  When doing a Scene Save with multiple slaves, each slave saves its current loaded preset numbers, but all
slaves save the new scene name.  Protea System Software has a Scene Save feature which stores the currently loaded
preset numbers, as well as the information stored within each preset.

To save a scene, press SAVE, then SCENE, then the scene number (1-50).  Once the desired scene number is either

scrolled to or numerically entered, press Save again, which prompts for a scene name.  Scene names are optional, but
recommended, and can use any text character on the keyboard, upper or lower case, up to ten characters.  When a scene
name is complete, press SAVE again to write to memory.  Recall a scene in the same manner, by pressing RECALL, then
Scene, then the correct scene number.  Note:  When using the remote control unit or PC control with several slave units, the
scene name is retrieved from the very first slave connected, but upon saving, all slaves get the name written.

5.13  CAPSLOCK

This key toggles between uppercase and lower case letters for preset names, scene names and the security

password.  Note:  The Security menu always opens with CapsLock set to lower case, meaning that passwords are best
entered as lower case characters.

5.14  GAIN

The GAIN keys only affect audio levels while in the EQ menu, with a range of +6dB to -

∞. 

 The Gain keys are

also used as up/down arrows to scroll through numbers for preset selection.

5.15  FACTORY  RESET

To clear all preset names and reset all controls to their flat, original factory settings, FACTORY  RESET may

be performed by simultaneously pressing and holding Esc and Flat while switching power on.   Caution:  doing this
will erase all current presets!

To do a factory reset on a slave unit, set back panel Switch "A" OUT and Switch "B" IN, then power up unit.

A 10 second countdown occurs on the LED character displays indicating a factory reset is about to occur.  The count-
down may be interrupted at any time by turning off the power or changing either switch on the back panel.  If the
countdown goes to completion, factory reset has occurred and "f r" is displayed.  As long as "f r" is showing, the Protea
Slave unit will not function until the Switch A and B are properly set for normal operation as shown in the System
Configuration Chart on page 20.

6. INTERCONNECT  FEATURES

6.1 AUDIO

All Protea audio connections use XLR and 1/4"  TRS (tip-ring-sleeve) phone jacks, with XLR pin 2 and the

1/4" TIP connector as (+).  Inputs are precision balanced, and outputs can be used balanced or unbalanced.  If an
unbalanced signal is fed to the input, the signal should be on the (+) connection and the (-) connection must be tied to
ground, or significant signal loss will result.  It is strongly recommended that balanced signals be used whenever
possible.   While a mono phone plug used as an unbalanced connection will automatically ground the (-) ring of the
jack, XLR plugs will not automatically do this so attention must be given to proper wiring.

A Note About Input Signal Levels:

There are no analog gain trim adjustments on the Protea processors, therefore all the processing (including

gain) is done in the digital domain.  The Protea processors were designed this way so that when digital inputs/outputs
become available, there will not be any gain stages left out of the all digital signal path.  As a consequence of this
design philosophy, it is important to feed the Protea processor with the proper nominal signal level to achieve good
signal to noise performance as well as headroom before clipping.  The Protea processors were designed to clip at
signal levels above +20dBu = 7.75Vrms which places the noise floor lower than -90dBu with the current 24-bit A/D and
D/A converters.  The optimum input signal level which should be fed into the Protea processor is 0dBu = .775Vrms.
This input level will allow 20dB of headroom while giving a nominal signal that is 90dB above the noise floor.
