6. Operation
6.1 Indicators
6.1.1 ON LEDs
Under normal operation, after the amp has started, all four green ON LEDs are
permanently lit.
6.1.2 SIGNAL/Protect LEDs (multifunctional)
The green Signal LEDs are illuminated when the voltage level at the output
reaches approx. 4 V; this corresponds to a power of approx. 4 W into a 4 Ω
load. The channel signal LEDs are illuminated red when the amplifier is in Protect
Mode (Mute), for example because of persistent DC-voltage at the outputs or
overheating.
6.1.3 I-OUT Output Current LEDs
The brightness is proportional to the output current in the corresponding chan-
nel.
6.1.4 CLIP LEDs (multifunctional)
The colour of the bi-coloured LED changes between orange and red, depending
on the clip intensity. Orange indicates light clipping, red indicates heavy clipping.
6.2 Controls
6.2.1 Volume Control
A volume control with 41 notched settings controls the audio signal. These
settings have been selected to correspond to human hearing characteristics
(logarithmically) and therefore guarantee an optimal range of settings for practical
applications. Each channel can be set individually.
Set the volume to zero before turning the amplifier on to prevent the occurrence
of sudden high volume levels which may cause damage to your hearing and
the speakers.
6.2.2 Gain Selector
A switch on the rear of the
Q-POWER 14
amplifier allows to select the overall
amplifier gain.
The
Q-POWER 14
amplifier has a 26 dB and 32 dB voltage gain setting along
with a 1,4 V sensitivity setting.
6.2.3 Clip Limiter Switch
This switch is located at the rear of the
Q-POWER 14
amplifier. It allows you to
activate the clip limiter function on the channels A/B and C/D respectively.
