20 SF-16M Matrix Amplifier Installation and Operation Guide
For Each Member
Output, A Sound
Scene Preset
Remembers:
• Current volume level
• Mute status
• Power status
• Current input
Note: A scene “snapshot”
command saves the
current
volume/input, so if you have an
override activated, the override
input and volume level will be
recorded in the scene preset.
Scene Presets
A Scene Preset is a “snapshot” of the current state of the system (volume, inputs,
mute, and power status). When you recall a Scene Preset these settings return
to just the way they were when the preset was saved. Create a Scene Preset by
sending a snapshot command (see page 34) via Ethernet or serial. You can also
build or edit a scene preset using the PC utility (see page 24 and video tutorial).
When you send a snapshot command to save a Scene Preset, all outputs are
included as members of that Scene, but it is possible to disable outputs from a
Scene membership or to add them manually using serial/Ethernet commands or
the PC utility.
Line 1:
Scene number and name.
Line 2:
Select this line to recall and activate the scene. Status is not indicated
here because a scene is not activated and then “released” like an override.
Line 3 and Following:
Outputs belonging to the Scene Preset, aka “members”.
Front/Back Panel
Sleep Timer:
Turns off the front panel display after the front panel keys and
knob have not been used for a period of time. Select a time period of 0, 1, 2, or
5 minutes. Select (zero) if the display should remain on. The display is turned
off automatically when entering standby unless the sleep timer is set to zero.
Brightness:
Brightness level of the keys and front panel display. Choose 100%,
75%, 50%, or 25%. Also accessible by the dim button on the keyboard.
Front Panel IR On/Off:
Disables / enables front panel IR sensor. If not required
for control, leave it off to avoid issues with sunlight or other interference.
Audio Sense Standby:
Choose standby mode: either Audio Sense standby
(AS) or Audio Sense + Trigger (AST). In AS mode, the SF-16M detects the
presence of audio to exit or enter standby (power-conserve). To use AST
mode, connect any 12V device to the trigger input on the back of the unit. With
AST mode on, a high-to-low transition triggers standby (automute), and a low-
to-high transition will bring it out of standby. Simply having a high or low level
present does not trigger the amp; it is the transition that triggers the change.
Network
This screen displays the status of the network, the native IP address, gateway,
subnet mask, and mac address. It is often convenient to turn DHCP on to
connect automatically to a DHCP network for initial setup. Once the SF-16M is
installed, use a static IP address and turn DHCP off. If the network settings have
changed but not yet committed, this screen displays a message.
Firmware
This screen displays the unit number, the system firmware and bootloader, and
the input board firmware and bootloader versions. To update firmware load the
new version onto a USB drive, insert the drive into the USB port, and select the
update firmware line.
Factory Defaults
If you need to clear all the settings in the SF-16M and return it to default values,
use the Factory Defaults command. The only way to restore custom settings is if
you have an archive saved on a USB drive or computer hard disk.
