DAC3 HGC and DAC3 L
Firmware Version 2.0 Upgrade Instructions
New Version 2.0 Feature:
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.
Enabling and disabling the COMPATIBILITY mode:
•
Simultaneously hold the
DIM/MUTE
and
INPUT-UP
keys for 3 seconds to activate or deactivate this
feature.
•
The
HT
light will be illuminated on all inputs when
COMPATIBILITY
mode is enabled.
•
The
DIM/MUTE
key will be disabled when
COMPATIBILITY
mode is enabled.
•
The
DAC3
will not respond to the
DIM
,
MUTE,
VOLUME-UP
and
VOLUME-DOWN
keys on the IR remote
when
COMPATIBILITY
mode is enabled.
Cautions:
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
!
