    • The invention relates to an amplifier for audio signals comprising a first (A.sub.1) and a second (A.sub.2) stage having a global feedback loop (B) between the output of the second stage and the input of the first stage, the second stage having a local feedback loop (B.sub.2) between its output and its input. Each feedback loop has a comparator element (C.sub.1). The amplifier comprises a means preventing the offset voltage present at the output of the first stage (A.sub.1) from being reinjected as input by feedback (in particular via the amplifier output). The local feedback loop (B.sub.2) is such that the second stage (A.sub.2) receives feedback at least continuously. The low frequency interference signals produced in the second stage (A.sub.2) are reduced by the feedback of the second stage (A.sub.2).

    • The invention relates to an amplifier stage comprising at least one module presenting a first transistor (T.sub.1) whose base forms an input terminal and a means to maintain a substantially constant current in the collector-emitter path of the first transistor (T.sub.1). Said means is comprised of a first current source (A.sub.1) connected to the collector of the transmitter (T.sub.1). A feed-back circuit has a direct voltage source (V.sub.3) arranged to maintain substantially constant the potential of the collector of the transistor (T.sub.1). It presents a path for the main current between a terminal (S'.sub.1) of the stage and the emitter of the transistor (T.sub.1). The value of said main current is a function of the voltage (V.sub.3) and of the potential (VCT.sub.2) of the collector of the transistor (T.sub.1); this potential remains substantially constant.
