Installation
Systems are generally delivered with modules (including sub-modules) and
associated rear connector units already installed and configured within frames to
your requirements.
Before installing or re-arranging modules and rear connector units in 2600
series frames the 2600 range and frames user guide should be consulted. Section
1.3 ‘Safety and pre-installation checks’ includes instructions that must be
followed. Section 2 describes how to install or re-arrange modules and rear
connector units in 2600 series frames.
5AA2626 rear connector units
Input & output connections should either be made to a 25 way D type plug (not
provided) per the table 1 pin out details below, or when the 3990 D type to
screw terminal adapter is used, per the details shown below.

13 N/A Chassis
Inputs are connected to the row marked ‘IN’. Outputs are
connected to rows marked outputs ‘OUT1 to 5’.
Input & output connections are made to twelve removable
Weco connectors
Pin columns for input & outputs are marked on the rear
unit '+' (In phase), ‘-' (Out of phase) and 'Earth sign'
(Screen). The same convention must be used to ensure
zero phase difference through the amplifier.
Front module
The 5AA2625 fits into the frame from the front and is secured by a
thumbscrew. This may be done with the frame powered.
A red LED, when lit, shows that the unit is receiving mains and the internal
power supply is functioning.
The front panel gain controls are factory set for unity. Turning the control
clockwise increases gain. When used as a single channel unit, use the channel 1
gain control only. Output level can be monitored from the front panel test
points.
Input termination. Units are delivered with high impedance inputs on both
channels. 600Ωtermination can be selected by fitting a jumper to the sets of
pins at the front of the module marked ‘CH1 600R’ and ‘CH2 600R’.
Single/dual channel. The unit is delivered set for dual channel operation. It can
be changed to single channel mode by moving the pair of jumpers (in the
middle of the unit) from the position marked 'DUAL' to that marked ‘SINGLE’. There are 5 outputs per channel. Any outputs without transformers fitted are
available as electronic ones. For the 5AA2625-2 with one output transformer
per channel, the output transformer is on output 1, for the 5AA2625-4 with two
output transformers per channel, the output transformers are on outputs 1&2, for
the 5AA2625-6 with three output transformers per channel, the output
transformers are on outputs 1, 2 & 3. When the stereo to mono function is
selected, the mono output is on output 5 for the channel selected.
The 5AA2626 rear connector can be used with the 3990 D type to removable
screw terminal adapter. Individual screened twisted pairs can be connected for
each input/output with hot (in phase) on the left, screen in the centre and cold
(out of phase) on the right. Inputs & outputs are shown on the unit.
Filtering. The unit is delivered with the CCIR roll off filter in circuit for both
channels. To bypass the filter for distribution of time code, move the jumper for
the relevant channel ('CH1' or 'CH2') from the position marked 'CCIR' to that
marked ‘OUT’. These jumpers are in the middle of the unit near the front.
Stereo to mono. The unit is delivered as a 5 balanced output dual channel
distribution amplifier. Moving the links marked ‘CH1 S>M’ and ‘CH2 S>M’
from ‘OUT’ to ‘IN’ provides a combined mono output on output 5 for channel 1
& 2 respectively.

per channel, the output transformer is on output 1, for the 5AA2625-4 with two
output transformers per channel, the output transformers are on outputs 1&2, for
the 5AA2625-6 with three output transformers per channel, the output
transformers are on outputs 1,2&3. When the stereo to mono function is
selected, the mono output is on output 5 for the channel selected.

3990 D type to removable screw terminal adapter
The 5AA2626-5 rear connector can be used with the 3990 D type to removable
screw terminal adapter. Individual screened twisted pairs can be connected for
each input/output with hot (in phase) on the left, screen in the centre and cold
(out of phase) on the right. Inputs & outputs are shown on the unit.

5AA2626-1 rear connector units
Input & output connections are made to two half-size DIN
41612 connectors, one for each channel. These are
mounted on a sub-assembly to allow cabling to be carried
out on the bench.
Pin columns for input & outputs are marked on the rear
unit 'I' (In phase), 'O' (Out of phase) and 'S' (screen). The
same convention must be used to ensure zero phase
difference through the amplifier.
Top two rows of pins on each connector are in parallel to
allow input connections to be looped out if required.
Outputs are connected to rows marked outputs 1 to 5.
Screen pins are connected to chassis.
A tie bar on the connector sub-assembly allows cables to be secured properly.
The sub-assembly must be secured to the rear unit by its two captive screws
after cabling.
When used as a 10 output single channel distribution amplifier, use channel 1
input.
For unbalanced inputs connect one leg (I or O) to screen. For unbalanced
outputs use one leg (I or O) relative to screen. Never connect an output leg to
screen directly. Unused outputs must be left floating.
