Installing new firmware to your Realiser A16
Rev 1.75 Oct 15 2019
Updating your A16 with rev 1.75 Oct 15 2019 is only necessary if your A16’s firmware is older. The
current revision of your firmware is found in SETTINGS>UPDATES/ABOUT as described below in step 5. If
an update is required please begin with step 1.
Issues addressed in this update
1) Previously when playing CDs or DVDs over HDMI or SPDIF and jumping or transitioning audio
tracks, a momentary audio stutter could be heard as the track began playing. This issue was
investigated by MDS and their solution has now been implemented in firmware rev 1.75.
Consequently the ‘Auto Mute’feature introduced in rev 1.70 is no longer required. However, it
remains in the menu as a general purpose programmable mute timer. For now, please keep
‘Auto Mute’ at the minimum 50ms value.
2) USB audio that was unintentionally left muted in rev 1.70 is now functioning normally again.
3) Audio bypass and HDMI 2.0 now function for all 4 HDMI ports. A revised menu for these controls
is described in the new features section below.
Update procedure
STEP 1. The new firmware for the Realiser A16 is uploaded through the micro-SD card slot on the front
panel. First, obtain a micro-SD card (commonly 16 GB) and ensure it is formatted as FAT32. Second,
create a ‘realiser’ folder in the root directory and copy the firmware file FIRMA001.SVS into the realiser
folder. Insert this micro-SD card into the slot on the front of your A16.
STEP 2. Power up the A16 ensuring the power indicator LED is steady green. You can power it up using
the remote control or by momentarily depressing either User A or User B volume knobs. Now turn off
the A16 by pushing in and holding in the User A volume knob for at least 3 seconds. The LCD screen will
switch off and the power indicator LED will turn red. Release the User A volume knob.
STEP 3. Push in and hold in the User B volume knob and, simultaneously, push in and release the User A
volume knob. Then release the User B volume knob. The action of holding in B and depressing A
activates the firmware update manager as shown below. The power indicator LED will also be blinking
green.
