DSP360 utilities include a security sec-

tion for password protected lockout, a

dBu/VU meter preference select, and a

device name display.

Security

There are four security modes in the DSP480 and DSP360: Off, Preset Lock, Parameter Lock, and Full Lockout. When

connected to a PC via the USB port, security settings made on the unit are read and used within the Protea NE software security

section, sharing the same passcode.

1.) Off (none) allows full access to all controls.

2.) Preset Lock allows full access while disabling the save function.

3.) Parameter Lock allows the user to recall different presets, but allows no changes other than mute.

4.) Full Lockout allows absolutely no local changes, but allows viewing of current settings.

To access the security menu, first press the Util button, then select the Security display line on the LCD. Use the data

wheel to select from the four security levels. If the unit is brand new and has never had a security code, or has had a factory

reset, a four digit code must first be entered before changing security status. Use the output select buttons 1-8 (recommended)

or the data wheel (0-9) to enter a new code, then press Enter on the LCD. The LCD then prompts the user to either change the

code to a new four digit number, or change the Security status to one of the other three options.

The only way to fully remove a security code once it has been entered is with a factory reset. This is done by turning the

power on while pressing Esc and Recall together, returning all settings, including user defined presets, to their original factory

settings. Note: In the event the four digit security code is forgotten, turn the unit on while pressing both the Esc and Util buttons.

dBu/VU Meter Select

The input and output meter scale is factory set so that a green LED flashing at 0 indicates a signal level of 0dBu, or

0.775Vrms. To change this to a VU scale, where 0VU = +4dBu (1.228Vrms), select the <Ref:> option in the Util menu to VU.

Note: Protea NE software for the DSP480 and DSP360 can only display LED meters in dBu.

Device Name

The device name is assigned from within Protea NE software, and is displayed in the LCD window.

4 .7f Factory Reset

To clear all preset names, reset all controls to their original factory settings, and delete the password from memory,

Factory Reset may be performed by simultaneously pressing and holding Esc and Recall while switching power on. Caution:

doing this will erase all user-defined presets!
