The DA2 adds an HDMI ARC connection. Your unit can now receive audio via an HDMI cable from ARC-enabled televisions. Audio Return Channel (ARC) can provide two-way communication between units allowing for volume control and lip-syncing functions to ensure audio and video are perfectly matched. This allows for more intelligent operation between components as well as less cable clutter. Make sure this feature is enabled in your TV’s setup menu.
The Lip Sync function is automatic with an ARC CEC connection. Lip Sync can
also be controlled with your unit’s trim function allowing adjustments of
audio to sync with accompanying video when CEC is defeated or with the optical
input.
The HDMI ARC input is designed to be used exclusively with ARC-compliant
televisions. If the source is not ARC compliant, use the optical connection
for digital sources.
Menus
The DA2 module is designed to work with firmware version 2.0 or higher. With
the appropriate firmware, your unit’s menus will automatically update to work
with the DA2’s new features.
New Input
HDMI ARC
HDMI (ARC) will be an option when selecting an input. It can be renamed and
enabled/disabled in the same manner as all other inputs.
New Setup Options
Digital Gain
sets have sound levels that are lower than typical music sources. Because of this, a volume boost has been added to the HDMI input making it louder. Since not every TV follows the same standard, the ability to adjust the default volume boost for HDMI is available in the SETUP menu. The ability to add and adjust a volume boost has also been provided for the two Optical inputs so that the Optical inputs’ gains can be adjusted as needed.
To adjust Digital Gain, enter the SETUP menu. Scroll to Digital Gain. Press and hold the INPUT knob to enter the sub-menu. Use the INPUT knob to choose the option to adjust- HDMI Gain, OPTI 1 Gain or OPTI 2 Gain. The VOLUME knob can be used to select a value between 0dB and +15dB.
HDMI CEC
Consumer Electronics Control (CEC) is a feature of HDMI that theoretically
allows users to control multiple connected devices through one Remote Control.
This can work fine in some cases when you want to turn on the television and
also power on other related devices, but there may be times when you do not
want this or other connected events to happen. To defeat CEC, enter the SETUP
menu using the INPUT knob as you normally would. Scroll to HDMI CEC. Use the
VOLUME knob to toggle ON/OFF. If you have a control system for your devices,
you will
want CEC defeated (OFF).
Many video sources such as broadcast video to television
HDMI CEC PWR
With CEC enabled, your unit can control a television’s volume, mute, and
unmute with compatible televisions. Your compatible television can also power
on your McIntosh unit. CEC will also ensure correct decoding and lip-syncing
automatically. You can defeat your unit’s power control while keeping the
other benefits of CEC by using the SETUP option called HDMI CEC PWR. Enter the
SETUP menu, and scroll to HDMI CEC PWR. You can toggle the setting ON/OFF
using the VOLUME knob. If HDMI CEC is off, this setting will have no effect.
Lip Sync Mode
The Lip Sync Mode setup option enables the Lip Sync Mode to be toggled between
AUTO (automatic) and Manual. In the AUTO mode, lip-syncing functions for a
connected HDMI ARC connected television will be handled by CEC.
Changing the Lip Sync Mode to manual will enable a TRIM option called HDMI LIP
SYNC DELAY.
New Trim Options
HDMI LIP SYNC DELAY
When the SETUP option Lip Sync Mode is set to Manual, the HDMI LIP SYNC DELAY
option will be available in the TRIM menu. Choosing this TRIM option will
allow a lip sync delay of between 0 milliseconds (ms) and 150 ms to be set in
10-ms increments. The lip sync delay will apply to HDMI, Optical, and Coax
inputs.
New Processing Power
In addition to standard format SPDIF PCM signals, your unit is now capable of processing Dolby Digital and DTS encoded multi-channel bitstreams through the Optical, COAX and HDMI inputs.
