5AA2626 Audio rear connector with D type socket (suitable for multi-core cable
with common screen)
5AA2626-5 Audio rear connector with two D type sockets (suitable for multi-core
cable with common screen)
3990 D type to removable screw terminal adapter
5AA2626-1 Audio rear connector with two ½ DIN solder tag connectors on a
removable sub-assembly (suitable for individually screened twisted
pair cable)
5AA2626-2 Rear connector with removable screw terminals
5AA-K Gain trimmer replaced by panel mounted knob (per channel)
5AA-OP600 600Ωoutput impedance option
A broadcast quality dual / single channel audio distribution amplifier with:
•Front panel gain controls and output monitoring test points for each
channel (optional gain potentiometers with knobs)
•5 balanced outputs per channel of which up to three per channel can be
transformer-coupled. Easily configured to single channel 10 output
distribution amplifier by link selection
•Electronic or optionally transformer balanced inputs (user selectable high
or 600Ωimpedance)
•Low impedance outputs (optional 600Ωimpedance)
•Input and output transformers achieve wide frequency response and low
distortion even at low frequencies using novel circuitry
•Two stereo to mono outputs available by link selection
•A link can be moved to bypass the roll-off filter for time-code distribution
•Requires the 5AA2626, 5AA2626-1 or 5AA2626-2 rear connector unit
•The 5AA2626 incorporates all input and output connections on a 25 way
D type socket, ideal for multicore cable with a common screen (the 3990
D type to removable screw terminal adapter is available as an option)

•The 5AA2626-1 has two ½ DIN connectors on a removable sub-
assembly, ideal for individually screened twisted pairs
•The 5AA2626-2 has removable Weco screw terminals
•All 2600 modules are independently mains powered maximising
reliability & isolation between modules.
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.
