5AA-OP600

600Ω output 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 600Ω impedance)

• Low impedance outputs (optional 600Ω impedance)

• 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 sub­assembly, 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.
