SF-16M Matrix Amplier Installation and Operation Guide 15

OPERATION

Front Panel Description

The front panel is operated by using three touch sensitive keys: Menu

, Back

, Dim

and a Multi-Function Knob

Multi-Function Knob Operation: Used to navigate through all menu items, the multi-function knob can scroll (clockwise

or counterclockwise) and select or de-select (press in). The open arrow  symbol is displayed when scrolling through

menu items. Once an item has been selected (by pressing in the knob), the arrow will ll in . Next, turn the knob to

adjust the value. Press in the knob again to de-select the menu item and scroll to the next item that needs to be adjusted.

Menu Button > Menu Screen

Menu options: Output Settings, Input Settings, Override, Scene Presets, Groups, Front/Back Panel, Network, Firmware

and Factory Defaults. The menu button also toggles the display between the main menu and output meters.

Back Button

Press to return to a previous screen. Pressing the back button repeatedly eventually returns to the main menu.

Dim Button

This button toggles through four brightness levels for the VFD and keyboard LED indicators. After a set period of time

(adjustable using the front panel or the SF-16M PC congurator), the VFD enters a screen saver mode (dark). The power

and button LEDs remain on at the dened level to show that the unit is receiving power. Any key press or knob adjustment

causes the VFD to return to the last selected brightness level.

Front Panel Menu Options

Output Settings > Quick Access

The Output Quick Access screen provides a “snap-shot” of key settings and the ability to adjust parameters for each

setting. To begin, select the output you wish to view. Turn the knob and push to adjust any parameter. Output settings

and descriptions are listed below:

• Output Number/Name:

Lists the current output that is being viewed or adjusted.

In this case, “Billiards” is a stereo output comprised of outputs 9 and 10.

• Volume:

This line shows volume level, or other status messages:

1. Volume - The output level, a range from -80 up to 0 dB attenuation. Adjustable by

a discrete value or using a volume up or down command. 1 dB increments in the

-40 to 0 dB range, and 2 dB increments in the -80 to -40 range.

2. Standby - The SF-16M is in a power saving mode, which is triggered by issuing a

standby command or using the back panel trigger. Affects all outputs.

3. Shutdown - Shutdown means the output cannot come on because of a short on

the output, overheating of the output (impedance too low), or hardware failure.

4. Overtemp - The output is off due to too high a temperature of output chips. This can be caused by a speaker

impedance that is too low or inadequate ventilation.

5. Poweroff - Power off mode (similar to mute) is set by the user. When power is turned on the output volume level is

set to the previous level, within the maximum turn on and minimum turn on levels.

6. Muted - The output is muted, which silences the output temporarily. Unmute restores previous volume levels.

7. Automute - No input signals are detected for any of the 8 outputs in the output bank. Output banks 1-8 and 9-16 are

separate, so if no audio is present on selected inputs to an output bank, the outputs automute.
