GENERAL INFORMATION
General Information
This manual gives general functional and technical information on the Seeport 2 portable mixer. The mixer has 2 outputs. A separate manual is available for the Seeport
4, which has 4 outputs.
Seeport has been designed with much thought to the user. With its modular design, it
offers versatility and an extensive range of functions, some which are not so typical
in small mixers, making it suitable for many types of applications. Typically these
include radio and television studio work, OB vans, film sound, location recording and
TV post production.
The ergonomic design and surface layout of Seeport has been much appraised over
the years, incorporating a high functional level into a compact, yet uncluttered user
surface.
Seeport is available in three frame sizes and with a range of different modules. Full
details of all modules are given in this manual.
Built to very high standards both mechanically and electronically, Seeport is robust
and extremely reliable in operation. All faders used are Penny & Giles long throw
(104 mm) conductive plastic. The frame mechanism provides a neat suitcase type
carrying solution. Weight has also been taken into consideration in the design, an 8/2
weighing approximately 9.5kg.
Various options are available for Seeport which are covered in section 4.
Further technical information is provided in the Seeport Service Documentation. This
is provided with each Seeport delivery or is available from Seemix Sound on request.

frequencies.
MIC / LINE
Mic/Line input selector. (Separate XLR-type connectors).
LOW
Parametric equalizer low end. +/-12 dB, 50 Hz to 1kHz peak/

AUX 2 have center off switches and no pots. Post fader may
be taken before or after AB ON switch (jumper selectable).
PAN POT
Pan pot for panning signal between A and B outputs when
A/B ON switch is depressed.
S/NORM SWITCH
With this switch in the S position, a phase reversal of the
signal is sent to output B. This provides therefore the ’S’ signal of an MS configuration on the AB outputs. The ’M’ signal
would be fed from a separate mic channel (in NORM position). In this way, two faders can be used for controlling an
MS signal. Note: The pan pot must be set centred for both
channels when used in MS configuration.
ON AIR LED
This is lit when the fader is open and the AB Switch is ON.
AB ON
Channel On switch. Affects stereo output only, leaving AUX
and PFL active.
PFL
Pre-fade listen, with LED. Jumper settings determine
whether PFL is cut when channel is On Air, or is independent
of On Air status.
PEAK
Overload LED.

MODULES
Telephone Hybrid Module TH3800
GAIN
+/-20 dB fine gain adjustment
EQ
Equalizer +/-12 dB, 150 Hz to 4,8 kHz peak/dip.
AUX 1-4
Aux output pre-post selectors and level pots. AUX 1/2 has a
center off switch and no pot. Post fader may
be taken before or after AB ON switch (jumper selectable).
SEND LEVEL
Level potentiometer for return signal to incoming caller. The
LEVEL LED indicates that the SEND level limiter is active.
SEND BUTTONS
Interlocking switches for selecting return signal to caller.
Caller may be sent any one of AUX1 or AUX2 signals
(jumper selectable), PFL, A+B (PGM) or an external signal
(EXT) connected at the back of the module.
”SET” OFF
”SET” OFF LED indicates that the telephone set is
disconnected. This is activated by the CONNECT button or
by CUE1 or CUE2 (jumper selectable). CUE1 or CUE2 may
be activated by any other channel when on air (eg. for red
light). This therefore avoids ringing interuption when for example a local mic is live.
CONNECT
This button activates the hybrid function itself and connects
the line to the channel. It also disconnects the telephone
set (100ms after making the channel connection) as mentioned above. Releasing the connect button breaks the connection to the mixer channel and re-connects the telephone
set (again after 100ms) to enable off air conversation. NB:
The set will only be re-connected when the relevant CUE
signal is not present, e.g. local mic which controls red light is
off air.
CALL
The call LED gives a visual indication of the presence of an
incoming call. This is useful when ringing has been deactivated by one of the cue busses when on air.
PAN
Pan potentiometer. Feeds main outputs if A/B ON switch is
depressed.
ON AIR LED
This is lit when the fader is open and the AB Switch is ON.
AB ON
Routes signal to A and B mix busses.
PFL
Pre-fade listen, with LED. Jumper settings determine
whether PFL is cut when channel is On Air, or is independent of On Air status.

MODULES
Module Information
The TH3800 can be used in several different ways, either as a straight hybrid (without interacting with the
rest of the mixer) or as an integrated mixer channel with routing to and from the mix busses.
The incoming line signal can be routed, via the AB ON switch, to the A and B master busses. It can also be
sent to the PFL bus as well as to all AUX busses either pre or post fade. However, the channel can only be
sent to either AUX1 or AUX2, not both. This choice is jumper selectable. The reason for this is that AUX1 or
AUX2 can also be selected as the return signal to the caller (SEND) (also jumper selectable). These jumpers
must therefore be set differently for the two signal paths in order to avoid a feedback loop. Further, if two
hybrid modules are used simultaneously, by setting these jumpers in ’mirrored’ positions for each module,
AUX1 and AUX2 can be used for cleanfeed mixes (N-1) for respectively line 1 and line 2.
The return signal (SEND) can be selected from AUX1/2 (as described above), PFL , A+B or an external
source. A+B would normally be selected when the line is to be used for transmission.
The module also has a channel out connector. This is fed from the post fade signal and provides an extra
output independent of the rest of the mixer. This enables the module to be used as a stand alone hybrid. For
example, the Channel Out is sent to an external mixer, and the output of this mixer is in turn connected to the
EXT input of the hybrid to provide the SEND signal to the caller. Any source connected to the EXT input can
be sent down the line for monitoring (SEND EXT). Similarly, any incoming telephone line signal can be monitored directly from the channel output connector.

The following jumper possibilities are available. Jumpers positions are indicated in the diagram below.

Module Information
The M3808 is designed for feeding presenters in the field with a mix of several monitoring sources. The module can feed 2 presenters simultaneously with independent mixes from 6 sources.
Two of these are the A and B outputs from the mixer, the four others are external sources which
are connected to the module via a 15-pin D-sub connector. Talkback from the mixer can also be
sent to each presenter.
The module is designed primarily for mono monitoring. Each presenter output is terminated as a
mono balanced pair on an XLR connector, allowing headphones to be driven over long cable
lengths. Left and right monitoring outputs are also available on XLR connectors for monitoring by
the engineer. Typically, these outputs might be fed to the EXT monitor inputs on the M3810 monitor module. Input levels for each source can be adjusted with +/- 15dB (common setting for both
presenters). Each presenter output has an individual main level control. The module occupies the
place of two normal input modules in the mixer.

Remote Control / Cue System
A remote control (fader start) solid state relay output from each audio channel and the stereo
master output is available. On the I3800 mono input module, fader start is activated when the
input selector is set to LINE. In the MIC position, the control goes instead to one of two solid
state relay cue (ON AIR) outputs. These can be used for example to drive limited capacity ’on
air’ or ’ready’ lamps. Maximum current through the switches is 100mA.
Both CUE signals can also be used to disconnect a telephone set that is connected to the
TH3800 telephone hybrid module, in order to prevent the set from ringing.
The CUE1 signal can be used to MUTE the MON L/R output and/or the PFL MONO output
(jumper selectable on the M3810 module).

TECHNICAL INFORMATION
Expansion Connectors
Two Seeport mixers can be connected and operated in a ’master/slave’ configuration. The 8 mixed outputs
from the one mixer (slave) are fed to the eight mix buses of the other (master). The connection is made via a
25-pin D-sub expansion cable. This allows, for example, two 8 channel mixers to be used as a 16 channel
mixer.
The cue signal buses in the two mixers are directly connected together.
The 0 volt references of each mixer are directly connected together.
Pin configuration of the multi-pin connectors and cable connections are shown below.
Insert Points Connectors
Insert points for inputs are connected on a 9-pin D-sub connector on the back panel above each module.
Pin-outs and views are shown below.
