3.2 Connecting and Setting Up
3.2.1 General Considerations
The ENC 1202 can be used as a desktop device, or installed in a 19” rack using one of the
optional rackmount kits (see p.44).
3.2.2 Connections
Proceed as follows to connect the ENC 1202:
1. Place the ENC 1202 in the desired location.
For practical reasons, we advise placing it close to the relevant signal sources or desti-
nations.
2. Use the supplied power cord to connect the ENC 1202’s POWER1 socket to a wall
outlet.
For critical projects where downtimes are not an option, we recommend adding a
second (optional) power cord. Connect it to the ENC 1202’s POWER2 socket and to a
separate power circuit. Doing so allows the second power supply to take over if the
POWER1 socket stops working.
3. Use a CAT-5 or higher cable to connect the ENC 1202’s PRIMARY Dante port to the IP
network or directly to your computer.
You have the option of creating a second, redundant, Dante network for the available
devices:
• Connect the ENC 1202’s PRIMARY port to a router/switch of the rst audio network.
• Connect the ENC 1202’s SECONDARY port to a router/switch of the second audio net-
work.
Be sure to connect the PRIMARY and SECONDARY Dante ports to two separate net-
works that are completely isolated from each other. Only then will Dante be able to
automatically switch to the SECONDARY port if an error occurs on the rst (primary)
network.
Caution:
• Dante redundancy requires that both the PRIMARY and SECONDARY interfaces are connected
using the samelinkspeed. For example, if the PRIMARY interface is connected to a 1Gbps
switch port, the SECONDARY interface must also be connected to a 1Gbps switch port.
Notes:
• NEVER change the routing settings of the secondary network. These are congured automati-
cally by Dante. Be sure to ONLY change the conguration of the primary network.
• Wherever possible, use a gigabit network topology with a minimum number of hops (e.g.
switches) among Dante devices.
• The SECONDARY port can also be used for daisy-chaining scenarios by setting “Dante Redun-
dancy after Reboot” (p.24) to “Switched”.
4. Connect the required devices to the ENC 1202’s inputs and outputs.
See also “3.1 ENC 1202 Panels” on page9.

Setting Up

5. If necessary, set the ENC 1202’s audio and network parameters.
This requires the use of a computer whose Ethernet port is connected to the primary
Dante network (or temporarily to the ENC 1202’s PRIMARY port). This conguration
routine may only be necessary once, because the settings can be stored.
Like many commercially available IP routers, the ENC 1202 contains a web interface
that can be accessed like a standard internet page. It also looks similar. That is where
the available parameters are located. See “3.3 The ENC1202’s address” for how to
access the ENC 1202’s parameters.
Notes:
• See “4 Conguring the Unit via its Web Interface” on page15 for the available parameters and
what they do.
• WiFi is only supported for conguration activities using the Dante Controller software (see
below). Audio data cannot be transmitted or received via WiFi.
3.3 TheENC1202’saddress
This device can be congured using one of the following internet browsers: Chrome,
Firefox, Internet Explorer (6.0 or newer) or Safari.
By default, the ENC 1202 is congured to automatically request IP addresses for both
Dante ports via DHCP.
If you already know the IP address, enter it into the browser’s address bar and press the
ENTER key on the computer keyboard:
192.168.1.34 (this is only an example)
As an alternative, you can enter the ENC 1202’s host name into your browser’s address
bar. The host name looks something like this:
ENC-1202-XXXXXX.local
“XXXXXX” represents the last six alphanumeric characters (without the colons) of the
PRIMARY Dante port’s MAC address. You can nd this MAC address on the ENC 1202’s
rear or bottom panel. The host name may look something like this:
ENC-1202-0e1530.local
(In this case, “0e:15:30” would be the last six alphanumeric characters of the MAC
address.)
If additional ENCHORUS devices are connected to the network, you can select them using
the “4.9 Browse Network” (p.42) tab.
3.3.1 DanteController
Another way to check the IP addresses of the remaining devices on the Dante network is
by using the “Device Info” item of the DanteController software. Dante Controller is free
software that can be downloaded from Audinate’s website (www.audinate.com). Dante
Controller detects and displays all Dante devices connected to the network and allows
you to both view information about them and to edit a number of settings.

Note:
• After logging in, you can open the web interface of other connected ENCHORUS-series’ devices
by clicking an entry in the “NAME” column on the ENC 1202’s “Browse Network” tab (see p.42).
WhatiftheENC1202’sIPAddressisnotdisplayed?
If Dante Controller fails to display the IP address of a connected ENC-series device, pro-
ceed as follows:
1. Leave Dante Controller running.
2. Disconnect the ENC 1202 from the wall outlet (to switch it o).
3. Reconnect the ENC 1202 to a wall outlet.
4. Click Dante Controller’s [Device Info] tab and wait ±15 seconds.
The ENC 1202’s IP address is displayed in Dante Controller’s list.
5. Assign a static IP address of the ENC 1202’s subnet to the connected computer.
The ENC 1202 is once again reachable.

3.4 ApplicationExamples
Use as Press Box
One or several ENC 1202 units can be used to set up a scalable audio distribution system
for the press: one of the 4 line inputs of the rst unit serves as input that feeds the 8 Line
Outs.
The RX Dante 01 input of the second and subsequent ENC 1202 units is also patched to
the respective 8 line outputs.
Tip: To save time when using multiple units, congure the second ENC 1202, save its set-
tings, use “Download Cong” on page16, and then “Restore Cong” on page16
to “copy” those settings to the third, fourth, etc., ENC 1202 units.

The Enchorus ENC 1202 provides a Delay function for each of the 8 line outputs, with a
delay time of up to 2.7 seconds. So does the ENC1101 (for its AES3 outputs). This can be
used to correct timing dierences just before the power ampliers, without the need for
an additional delay line controller, etc. For xed installations, this is probably the easiest
way to create a speaker matrix.

The Enchorus ENC1202 acts as matrix and ENC1101 as signal distributor for the power
amprack. If the power ampliers only have analog inputs, a second ENC 1202 can be
used instead of the ENC1101.

For mono outputs, you can use two of the 8 internal mixers to prepare the desired mix
for the left and right channels respectively. That signal could be transmitted to a second
Enchorus ENC1101 or ENC1202 via Dante to feed additional outputs.
This allows you to feed the entire power amp rack via Dante, reducing the cable count to
just a single CAT-5 (or two for a redundant setup).
