Benchmark Firmware Upgrade Kits for DAC2

Field-Installable Upgrade Kit for DAC2 HGC, DAC2 L, DAC2 DX and DAC2 D

Overview:

The revised user interface is more responsive to user commands and it is more compatible with automation systems. A new AUTO-ON function allows automatic startup using a switched AC source. The DIM function has been improved so that DIM always reduces the volume by 20 dB from any volume control setting. The volume control setting is stored in nonvolatile memory and is recalled when unit is turned on. The DIM state (DIM on or DIM off) is also stored in memory.

-USB MODE WARNING-

After installing the upgrade kit your unit will be reset to the factory defaults including the USB mode. Factory default is USB 1.0 and if you were using USB 2.0 you will need to change the USB setting back to 2.0 by holding the input up and down buttons at the same time (or the USB on the remote) for a full 3 seconds.

DAC2 HGC and L:

Version 2.4 is designed to make your DAC2 HGC and DAC2 L manufactured before 11/14/2018 easier to use. This upgrade makes the user interface on the DAC2 HGC and DAC2 L resemble that of the DAC3.

DAC2 D:

Version 2.3 is designed to make your DAC2 D manufactured before 11/14/2018 easier to use. This upgrade makes the user interface on the DAC2 D resemble that of the DAC3.

New features in Version 2.3 & 2.4:

• Added COMPATIBILITY mode to provide improved compatibility with LA4 and HPA4 line amplifiers. This feature sets the volume control to maximum on all inputs (HT light on, same level as HT mode). It also disables the MUTE and DIM. The remote control VOLUME and INPUT UP/DOWN keys will be ignored in this mode.
• Volume control is more responsive when moved slowly.
• EEPROM setting storage is now fully redundant to prevent data loss and data corruption.

Kit includes:

• Detailed instructions
• Firmware chip
• Jumper
