Field-Installable Upgrade Kit for DAC3 HGC and DAC3 L
(Not compatible with the DAC3 DX)
New features in Version 2.0:
Preamp COMPATIBILITY mode
Version 2.0 adds a preamplifier COMPATIBILITY mode. This mode disables the MUTE and DIM functions and places the volume control in the unity-gain HT position. Use this mode when the volume is being controlled by a downstream line amplifier such as the Benchmark HPA4.
When paired with an HPA4, the DAC3 and HPA4 can be controlled by a single Benchmark IR remote control. The HPA4 provides volume control, DIM and MUTE functions. Both units switch inputs in a coordinated fashion so that all digital and analog inputs are available. Place the DAC3 in compatibility mode and connect it to XLR input 1 on the HPA4. Select "Benchmark DAC on XLR1" in the HPA4 REMOTE menu.
- Firmware chip
- Replacement cover screws
If you are located in a country served by our distributor network, you may not be able to order directly from our store. If the checkout option is not available, you will need to call or email our customer service department to order your kit.
The DAC3 circuit boards and the software chip can be damaged by static electricity. Use of an ESD wrist strap is recommended. If a wrist strap is not available, hold chassis with one hand while inserting chip and moving jumpers. Do not touch the circuit board until your other hand is making contact with the chassis.
The software chip will be damaged if it is inserted backwards. The white line must face the rear panel of the DAC3!
