USER MANUAL - ANDANTE ACTIVE SPEAKERS
Voltage selector switch. The product shall be preset to the voltage of your location, but it is
recommended to check this before first operation. Available settings are 230V and 115V.
Power switch. Switches the product on and off.
AC inlet. Connect the supplied AC cord here.
Fuse holder. The fuse can be removed and exchanged by turning the holder and pulling out the
holder tray. Switch the unit off and disconnect the AC supply before doing so. Replace fuses
only with same value and rating. If the fuse blows a 2nd time, submit product for repair.
CH1 Audio input. This is an electronically balanced input which accepts either ¼’’ TRS plugs or
male XLR plugs.
Line/Mic sensitivity switch. Depending on the signal level supplied to the audio input (5), the
sensitivity can be selected between Line (released position) and Microphone (pressed posi-
tion) level. If the output of the feeding source is unknown, set the sensitivity to Line first and try
whether the audio level is sufficient.
Ground lift switch. In case of a mismatch between ground potentials of this product and the
feeding source, this switch may help by making the audio signal ground “floating”.
High pass filter for input. Applies an 80Hz 2nd order high pass filter to the input signal. This
filter will most likely be used when the input signal comes from a microphone and the input
sensitivity (6) is switched to MIC. It helps to reduce low-frequency rumble which is easily picked
up by microphones due to handling noise. Do not use this function with a line signal if you
require full-range audio reproduction.
Signal level indicator (same for all three input channels). This is a 2-color LED red/white which
will illuminate its white element when the signal level is at -30dB. This is a good indication –
even when the volume is down – to see whether an input signal is present. The red element
will light up at 0dB indication that the recommended nominal internal level is reached. For best
dynamic headroom, it is recommended to not exceed this point.
Level control (same for all three input channels). Turning this control completely counterclock-
wise will reduce the respective signal to its minimum, while turning this control clockwise
increases the volume of the respective signal. Obey the signal level indicator (9) to not exceed
recommended nominal levels.
CH2 TRS Audio input. This is a 3.5mm TRS socket with switching contacts, meaning that once
any connector is inserted into this socket, the RCA input of CH2 (12) is disabled. The 3.5mm
TRS socket is ideal for mobile player sources. Note that depending on the link mode switch
(14), the stereo channels are either summed up to a mono signal and played by the internal
speaker, or the left channel of the source is played by the internal speaker and the right chan-
nel of the source is sent out via the Link connector (16).
Functional Description
Andante speakers offer a user interface which resembles a basic 3-channel mixer. While the main
input (CH1) is supposed to be a mono signal, the auxiliary inputs (CH2 and CH3) can be stereo signals,
of which it can be decided whether they are summed to mono and played by the internal speaker or
whether the left channel is played by the internal speaker and the right channel is sent to a 2nd
speaker. Various filter options and a possibility to connect a subwoofer are provided.
