Back Panel Connections - T+A A 3000 HV User Manual

The A 3000 HV features complete and consistent channel separation in the signal processing stages (double-mono
construction), and for this reason the input and output sockets are also arranged in strict symmetry relative to the centre
of the machine.

Back panel connections

IN UNBALANCED
(asymmetrical signal inputs)
Asymmetrical amplifier input (Cinch) with an input sensitivity of 1.5 V
The Cinch sockets, Left and Right Channel, are connected to the pre-amplifier's
output sockets of the same name (see Appendix A).
IN BALANCED
(symmetrical signal inputs)
Symmetrical amplifier input (XLR) with an input sensitivity of 3.0 V
Input for pre-amplifiers with symmetrical outputs. The XLR sockets, Left and
Right Channel, should be connected to the pre-amplifier's sockets of the same
name (see Appendix A).

The appropriate type of connection (UNBALANCED
selected using the 'INPUT SELECT' switch.

In Mono mode please use the left-hand socket
(High Current Mono Input).
Loudspeaker terminals
The A 3000 HV is equipped with two pairs of loudspeaker terminals. The
terminals are plated with a layer of highly conductive, corrosion-resistant
rhodium in order to ensure excellent electrical contact with minimum transfer
resistance.
Always use high-quality loudspeaker cable with forked speaker lugs to connect
your loudspeakers.
Bi-Wiring
The two pairs of terminals are ideally suited for use in the bi-wiring arrangement
in conjunction with high-quality loudspeakers. For bi-wiring mode connect the
bass range to output A, and the mid-range / treble range to output B (see wiring
diagram on page 34).
Dual-zone mode
Alternatively two pairs of speakers can be connected to the machine (dual-zone
mode). The impedance of each speaker must not be lower than 4  (DIN
rating).
