rates, the ULTRA-CURVE PRO will be muted for approx. 1 sec., as all the filter parameters have to be recalculated.

In purely analog mode the 48 kHz rate should be used. Apart from the fact that the high sample rate gives the widest frequency response and correspondingly the best possible sound, at this rate the fastest signal processing takes place.

VIEWING ANGLE

Viewing angle controls the contrast adjustment for the display, in increments from 0 to 31. A second possibility to adjust display contrast is pressing cursor UP or cursor DOWN respectively while pressing the SETUP key.

RTA LOCK

When RTA lock is switched on, it is not possible to enter RTA mode. This is designed to prevent unauthorized or accidental selection of this mode. RTA LOCK should only be deactivated when the ULTRA-CURVE PRO is to be used specifically to analyze sound, or if it is to be used in conjunction with another ULTRA-CURVE PRO operating as an equalizer solely for analysis purposes. (Think of the consequences of the situation where you are using the ULTRA-CURVE PRO as a PA equalizer, and somebody, by accident, presses the RTA key. This could even, in the worst case, result in the concert sound which you had so carefully equalized being replaced by the pink noise of the analyzer, and this at the full power rating of your system!)

SECURITY

The SECURITY function offers effective protection against unauthorized use of the ULTRA-CURVE PRO. UNLOCK means, that all functions may be accessed, with the exception of the programs which are secured under PROTECT MEMORY. LOCK prevents any of the adjustment parameters on the device being accessed, the only exceptions being the DISPLAY of the present equalizer setting, plus the input and output level with the LEVEL METER. The only other way to make changes is via MIDI. In order to use the SECURITY function, a PASSWORD must be entered, which is done using the cursor keys and the softkeys. The softkeys are used to select the letter or symbol to be used, and they have the following functions:

Softkey A = confirms entry of the password and immediately activates the LOCK status.

Softkey B = and C = move the cursor left and right within the password.

Softkey D = erases any characters which may have already been entered.

To unlock: go into the SETUP menu. The relevant password field is immediately accessed, and the password may be re-entered. This causes the ULTRA-CURVE PRO to return to the unlock status. If the device is locked without entering the password, simply enter OK to unlock.

+Do not forget the password! If this happens, there is only one way to remove it: You must open the casing of the ULTRA-CURVE PRO, and take the battery out for a short while. After replacing it, and switching back on, the original factory presets will be reloaded. Warning! Doing this means you loose all your programs, and void the warranty!

PROTECT MEM

The protect memory function switches the write protect for the program memory on and off. You can use a password in this case, too.

EQ LO/EQ HI

The two functions EQ LO and EQ HI determine the area of program memory which will be protected by the protect memory function. EQ LO determines the lowest, EQ HI the highest program number of the protected area. Switching OFF means the protect memory function is deactivates only for the equalizer.

RTA LO/RTA HI

The two functions operate identically to EQ LO and EQ HI, except they determine the protection of the RTA programs. All the SETUP settings are stored when switching off the ULTRA-CURVE PRO, and remain unchanged until you re-edit them.

Refer to the MIDI SETUP for all MIDI settings.
