Product Overview: The DMHD1000
is an add-on HD Radio tuner you connect to your existing car stereo, factory or
aftermarket. HD Radio benefits include:
- Sound Quality: Radio stations can
broadcast more information more accurately with a digital signal,
without static or fading in and out. HD Radio describes it as "FM
stations with CD-quality sound and AM stations with FM-quality sound."
- Multicasting: Multicasting means
stations can split their signal into two or more different feeds of
programming. This potentially gives you two different radio shows or
songs on the same frequency (for example, 95.1 would become 95.1-1 and
- Text information: Stations can
send digital text information to be be displayed on your radio, in this
case the Commander LCD display. Typical broadcast information includes
artist and song title, weather, or traffic information.
Reception Modes: Along with HD
Radio digital transmissions, the DMHD1000 receives analog AM and FM stations, as
well as RDS (Radio Data System) information.
Seek Modes: In addition to
manual tuning, you can seek stations in three different modes; All (all
stations), HD (HD Radio stations only), and Preset (only the stations you've
Preset Tuning: The tuner allows
you to store up to 20 presets, five in each of the four preset banks. Toggle
though the preset banks (A, B, C, and D) using the Bank button. Directly access
presets in the current bank using one of the preset buttons (1-5).
Display: The Commander has
a 4-line display with several different modes. The Status Line across the bottom
is common between the display modes. The Status Line shows the preset bank,
preset number, seek mode, reception type (AM, FM, RDS FM, HD), and signal
strength. When tuning an analog AM or FM station just the band and frequency are
displayed on the upper three lines. HD Radio stations offer three options;
artist and song title both in a large font, Frequency in a large font and band,
artist, and song title in a smaller font, and artist and song title for all the
multicast channels on the current frequency. With RDS equipped FM stations you can
display the station name and the RDS text, or the frequency and the RDS text.
The display brightness and contrast are both adjustable. Dimensions:
Width=4.727", Height=1.571", Depth=0.695".
FM Modulator: The receiver's
built-in FM modulator can be set to any frequency from 88.1 MHz and 107.9 MHz
(in 0.2 MHz steps). The FM modulator can be turned off if not in use. The
modulator is wired and plugs into the antenna input of your radio. The benefit
of using an HD Radio tuner even with no line level input on your existing radio
is reception clarity. When tuning a digital station you'll hear no static and
stations won't fade in and out, even AM.
The wired commander houses the display and controls, including:
- Power: Turns the receiver
- Menu: Accesses the menu
