Press ENTER to select and store the parameter value or press ESC to cancel the selected value and return to the old value. Pressing HOME has the effect of pressing ESC then HOME, so the selected value will be cancelled and the menu will return to the top of the menu tree. Parameters that toggle or select among a list of options will wrap around when you reach the end, but parameters that adjust numeric values will not wrap around once the maximum or minimum value is reached. While adjusting a parameter, the UP/ DOWN button must be held down briefly before the repeat rate increases. © Polycom, Inc. 27 VORTEX EF2280 Reference Manual LCD MENU STRUCTURE System Overview Table 3 below shows a summary of EF2280 parameters and their ranges. .

This command controls whether or not status messages are sent. EF Bus Reference. This designates which EF2280 device, when multiple devices are linked together, will put one of their echo canceller references on the EF bus to be used as the EF bus reference. Error Messages. When the front panel is locked, you can see the parameters but you cannot change them. The default passcode is aspi (case is important). Front Panel Passcode. At the FRONT PANEL PASSCODE menu, press ENTER and then enter a passcode and press ENTER until you reach the end of the screen. Device ID. Controls the contrast level of the front panel liquid crystal display (LCD). Higher numbers result in darker characters on the display, lower numbers result in lighter characters. Meter. When the non-volatile memory is locked, you can query the settings but will get an error if you try to change them. Non-Volatile Memory Password. Cycles power on the EF2280. © Polycom, Inc. 29 VORTEX EF2280 Reference Manual LCD MENU STRUCTURE INPUTS The input menu allows the user to adjust functions related to the input signals to the EF2280. This menu contains ACOUSTIC ECHO CANCELLATION, AUTOMATIC GAIN CONTROL, AGC MAXIMUM, AGC MINIMUM, GAIN ADJUST, LEVEL MIC/LINE, MUTE, NOISE CANCELLATION, NOISE CANCELLATION LEVEL, PHANTOM POWER, REFERENCE ASSIGN, and AEC SUPPRESSION. The menu is organized around the Inputs (1-8) and (A-D), so that you first select an input and then select settings for that input. You can also choose to apply the settings to all Inputs, Inputs 1-8, or Inputs AD. Inputs 1-8, A-D Acoustic Echo Cancellation (In 1-8) Automatic Gain Control (AGC), In 1-8 AGC Maximum (In 1-8) AGC Minimum (In 1-8) Gain Level Min/Line (In 1-8) Mute Noise Cancellation (In 1-8) Noise Cancellation Level (In 1-8) Phantom Power (In 1-8) Reference Assign (In 1-8) AEC Suppression (In 1-8) Acoustic Echo Cancellation. This allows you to enable or disable the acoustic echo canceller on a particular channel. The default setting is 15 dB for microphone signals and 0 dBu for line level signals. See "Level" above for setting mic/line level for Inputs 1-8. The LEVEL INDICATOR on the front panel automatically reflects the level of the channel whose gain is being adjusted. Figure 21 below shows the gain adjust on Inputs 1-8 and A-D and the matrix crosspoints. Input Channel (1 of 8) Matrix Cross point Output Channel (1 of 12) Mic Preamp Adjustable 33 to 53 dB Matrix Cross Point Adjustable 20 to -100dB Gain Adjust +20 to -100dB Output Matrixer Figure 20.
