3.2 Connecting and Setting Up
3.2.1 General Considerations
The ENC 1201 can be used as a desktop device, or installed in a 19” rack using one of the
optional rackmount kits (see p.47).
3.2.2 Connections
Proceed as follows to connect the ENC 1201:
1. Place the ENC 1201 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 1201’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 1201’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 1201’s PRIMARY Dante port to the IP
network or directly to your computer.
You have the option of creating a redundant Dante network for the available devices:
• Connect the ENC 1201’s PRIMARY port to a router/switch of the rst audio network.
• Connect the ENC 1201’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.25) to “Switched”.
4. Connect the required devices to the ENC 1201’s inputs and outputs.
See also “3.1 ENC 1201 Panels” on page9.

Setting Up
The ENC1201’s address
ENC 1201 Version 1.0 Page 11
Caution:
• It is recommended to switch phantom power of an input o BEFORE connecting the XLR plug to
the desired input. See “PHANTOM POWER” on page30. When using condenser microphones
that require phantom power, be sure to activate that setting for the relevant inputs AFTER con-
necting the XLR plug.
5. If necessary, set the ENC 1201’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 1201’s PRIMARY port). This conguration
routine may only be necessary once, because the settings can be stored.
The ENC 1201 contains a web interface that can be accessed like a standard inter-
net page, like many commercially available IP routers. That is where the available
parameters are located. See “3.3 The ENC1201’s address” below for how to access the
ENC 1201’s parameters.
Notes:
• See “4 Conguring the Unit via its Web Interface” on page16 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1201’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 1201 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 (the following is only an example):
169.254.195.191
As an alternative, you can enter the ENC 1201’s host name into your browser’s address
bar. The host name looks something like this:
ENC-1201-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 1201’s
rear or bottom panel. The host name may look something like this:
ENC-1201-0e10de.local
(In this case, “0e:10:de” would be the last six alphanumeric characters of the MAC
address.)
If other ENCHORUS devices are connected to the network, you can select them using the
“4.9 Browse Network” (p.45) tab.

Setting Up
The ENC1201’s address
ENC 1201 Version 1.0 Page 12
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 1201’s “Browse Network” tab (see p.45).
WhatiftheENC1201’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 1201 from the wall outlets (to switch it o).
3. Reconnect the ENC 1201 to a wall outlet.
4. Click Dante Controller’s [Device Info] tab and wait ±15 seconds.
The ENC 1201’s IP address is displayed in Dante Controller’s list.
5. Assign a static IP address of the ENC 1201’s subnet to the connected computer.
The ENC 1201 is once again reachable.

Application Examples
ENC 1201 Version 1.0 Page 13
3.4 Application Examples
Stand-aloneMixerforPresentations
Among other things, the ENC 1201 can be used as stagebox and mixer for presentations:
connect the speaker’s microphone (or wireless receiver) to the MIC IN 1 socket and an
audio source (or the audio output of the speaker’s laptop) to MIC IN 3 and 4, using a suit-
able break-out cable (stereo mini-jack into 2 male XLR plugs).
Use one of the ENC 1201’s internal mixers (see p.44) to balance the voice with the
music/video soundtrack. Each microphone input provides an EQ and a phase inversion
setting that can be used to ne-tune the sound without any external gear. The resulting
mix is transmitted to the ENC 1201’s line outputs assigned to the LINE OUT 1~4 socket
(RJ45).

Studio
If the DAW you are using supports Dante, the Enchorus-series devices are an ecient and
exible solution for studio wiring. Since the system is modular, its topology and scale can
be quickly adapted to the session.
Consider positioning an Enchorus ENC1201 (8x MIC IN, 4x LINE OUT) close to the instru-
ments or voices you wish to record to keep cable runs to a minimum. Adding an Ethernet
switch will make patch bays obsolete.
An ENC 1102 allows you to take advantage of your outboard gear’s digital AES/EBU inputs
and outputs. Guitar processors, synthesizers, etc., with digital outputs can also be con-
nected to the ENC 1102 (i.e. in the digital domain).
