DT22-240 INSTALLATION MANUAL
Introduction
Thank you for choosing the ELAN DT22-240 Dual AM/FM Tuner. The ELAN DT22-240 Dual Tuner
is two AM/FM digital tuners in one standard-sized audio component. Each tuner has its own
audio output so that each may be listened to independently. The DT22-240 features a total of
396 station presets per chassis. When used in conjunction with ELAN Touch Panels, the com-
bination of Direct Access tuning and a plethora of Presets makes control of the DT22-240 easy
and intuitive – from anywhere in your home.
The DT22-240 includes a front panel IR receiver, full function handheld remote, and rear panel
control ports for IR, VIA!NET and serial control. Two-way feedback, including station call let-
ters, frequency, genre, song name and artist, can be displayed on any ELAN Touch Panel or
Olé Interactive Touchpad without the use of an SS1, SC1 or SC4. The DT22-240 displays data
(where available) in the EU from RDS.

DT22-240 INSTALLATION MANUAL
Rack Mounting
When mounting the DT22-240 Tuner in an equipment rack, use the included Rack Mount
Brackets for secure mounting and proper ventilation. The DT22-240 requires two rack spaces.
To install the DT22-240 into a standard 19” equipment rack:
1. Slide the rack mount bracket onto the DT22-240 chassis from the front as shown in Figure
C-1.
Figure C-1
2. Ensure that the brackets are flush with the front of the unit. Install each of the eight screws
(included) through the side mounting flanges into the holes in the sides of the unit as shown in
Figure C-2. Hand tighten screws! Over-tightening could cause damage to the DT22-240 Tuner.
Figure C-2
3. Once the brackets are securely mounted, install the entire assembly into a standard 19”
equipment rack from the front using four rack screws (not included). Two rack spaces will be
used. See Figure C-3.

VIA!NET
Use the VIA!NET ports when controlling the DT22-240 with ELAN Touch Panels, SC-1 Serial
Controller, SS1 System Station and/or other VIA!NET devices. The VIA!NET ports on the DT22-
240 can be daisy-chained between chassis and other VIA!NET devices.
Use an RJ-45 to RJ-45 interconnect cable to make all VIA!NET connections.
Use the following diagram when connecting a S86A/S86P and not using a SPP.
If there is not a System SS1 or System SC1 in the system, make the following connections.

AM Loop Antenna
DT22-240
AM Loop Antenna
The AM antenna is connected to the terminals marked AM/GND. These connections are not
polarity sensitive, so it does not matter which wire is connected to the GND or AM terminals.
To prevent unwanted noise, place the antenna as far away as possible from other electronics,
speaker cords, power cords and amplifiers.

DT22-240 INSTALLATION MANUAL
FM Antenna
Connect the included FM antenna to the FM F (coaxial) jack. Generally, a T-type twin lead
antenna will be sufficient; if you live in an area where the FM signals are particularly weak, it may
be necessary to install an outside or rooftop antenna.
If standard FM broadcast frequencies are available via your cable service, you may connect your
75 ohm FM antenna jack to your cable system. Please contact your cable service to discuss
this option.

Rear Panel Power Switch
The DT22-240 master power switch is located on the rear panel. The switch must be in the ON
position to allow the tuner to operate. To reduce power consumption when away for extended
periods of time, set the master switch to the OFF position. To return tuner to normal operation,
set the switch to the ON position.
Rear Panel Power Switch
Operation
DT22-240 provides intuitive control of its various functions via its front panel buttons as shown
on the next page, control with Touch Panels and Olé Touchpads, and the remote control with its
hard wired IR (for local and remote operation). DT22-240 is essentially two completely indepen-
dent AM-FM radio tuners (add another DT22-240 for a total of four)—each of which can be tuned
independently so that different audio channels play in different rooms.
From the interface within each zone you can:
• Change channels (either by preset or direct tuning)
• View RDS information (on supported panels)
Default Display
The default display, as shown below, provides information about the channel each tuner is cur-
rently tuned to, including category name, channel number, channel name, artist name, and song
title.
