The SEA 1 subwoofer EtherCon adapter

Thank you for purchasing a Neumann SEA 1 subwoofer EtherCon

adapter. This Neumann accessory is designed to compliment

Neumann‘s extensive range of studio monitors.

The Neumann mounting hardware range gives increased signal

interconnectivity and mounting ﬂexibility, for the cabinets and the

electronics.

About the SEA 1

In multiple subwoofer systems, control signals, such as volume

control signals, must be transmitted to all subwoofers to ensure

that they all deliver the volume set for the whole system.

The SEA 1 subwoofer EtherCon adapter facilitates the connection of

several subwoofers to a single NRC 1 or NRC 2 remote control or to

any RS-232 data source.

The subwoofer EtherCon adapter is a small black aluminum box

with 4 Neutrik EtherCon® sockets. One SEA 1 can serve as a control

data hub for up to 3 subwoofers. For larger systems, several SEA 1

can be used. The SEA 1 is compatible with Neumann RC cables or

standard CAT5 cables.

Instructions on controlling the volume and other functions can be

found in the operating manual of the corresponding remote control

and in the „Control Protocol“ document available on the subwoofer

pages at www.neumann.com.

Using the SEA 1

WARNING

Danger of hearing damage due to sudden high sound pres-

sure levels!

Audio signals that are present at switch-on of a subwoofer or

that can be present during operation, can create sudden, very

high sound pressure levels which can damage your hearing.

XAlways lower the output level of the audio source and set the

volume control of your remote control to a low level before

connecting the remote control to the subwoofer, either directly

or via an SEA1, or before starting the audio source (pressing

“play”).

If – with an audio signal present – you remove the Neumann

NRC 1 remote control while the switch VOLUME CONTROL of the

subwoofer is set to „VOLUME CONTROL“ or you set the switch

VOLUME CONTROL to „DISABLE“ while the Neumann NRC 1

remote control is connected, the system output level is immedi-

ately set to 0 dB. This can create sudden, very high sound pres-

sure levels which can damage your hearing.

Always lower the output level of the audio source before

removing a Neumann NRC 1 remote control, either directly

connected or via an SEA 1, or – with the NRC 1 remote control

connected – before setting the switch VOLUME CONTROL of

the subwoofer to “DISABLE”.

SEA 1 | 7

CAUTION

Material damage due to improper use of cables!

If you insert a network cable that is connected to a subwoofer or

an NRC 1, either directly or via an SEA1, into a network socket,

the network device and the subwoofer can be damaged.

Only connect the subwoofer(s) and the SEA 1 to Neumann

remote controls or devices that deliver a RS-232 signal using

a high-quality Neumann RC CAT5 cable (see below). Do not

use a “crossover” type of CAT5 cable.

XConnect up to three subwoofers as shown:

Since power for the device is supplied from the „SUB 1“

socket, a subwoofer must always be connected to this

socket.

XConnect more than three subwoofers as shown:

The following table shows the maximum number of subwoofers that

can be controlled by several SEA 1:

Number of SEA 1

in a daisy chain

1 2 3 4

Max. number

of connected subwoofers

3 5 7 9

It is possible to control more than 9 subwoofers using addi-

tional SEA 1. However, the subwoofers connected to later

SEA 1 in the chain may suer from a noticeable latency in

volume level changes. It is therefore not recommended to

daisy chain more than 9 subwoofers.

SEA 1 | 9

Cleaning and maintaining the SEA 1

CAUTION

Damage to the product caused by liquids!

Liquids entering the product can cause a short-circuit in the

electronics and damage or even destroy it.

XKeep all liquids away from the product.

XBefore cleaning, disconnect the SEA 1 from the subwoofer.

XUse a soft, dry, and lint-free cloth to clean the product.
