6. INFRARED REMOTE CONTROL

The equipment includes as standard a remote control and its infrared detector to control
general volume and mute. Three keys control these functions:
•
•
•
Always try to point the remote handset directly toward the PKUB front panel REMOTE
detector, within range and preferably in front of it, without obstacles between them. The maximum
response distance for the emitting/receiving system depends on the incidence angle of infrared signals
on the receiver, on the battery load in the remote handset and on the existence of ambient interfering
signals, such as other infrared signals or emissions coming from certain types of fluorescent lamps.

7. CONSIDERATIONS

7.1. Starting up

This is directly done by means of the mains switch (24), the blue ON indicator (8) remaining
lit in blue on the front panel when the unit is powered on.
In a complete audio installation, it is important to start up the equipment in the following
sequence: sound sources, mixer, equalizers, active filters and finally power amplifiers. To turn them
off the sequence should follow an inverse pattern.

7.2. Gain and input levels

The PKUB has an effective adjustment system for the microphone input (channel 1)
sensitivity, allowing a precise matching to input levels. This system uses a back panel trimmer (15) for
this setting.
Also, two front panel rotary knobs (INPUT 1 and INPUT 2) allow to adjust the level of signals
sent from Input 1 and 2 to the mixing bus of the equipment for a later amplification that will be
proportional to the front panel VOLUME control setting.

7.3. Equalization

Tone controls (10, 11, 12) provide ±15 dB gain/attenuation for each of the three bands,
centered on 100Hz, 1.8kHz and 10kHz. Because of the intended applications of this unit, its tone
control system is adjustable by screwdriver, thus preventing unauthorised or unintentional use during its
normal operation.

7.4. SIGNAL indicators

The "SIGNAL" indicator (2) lights up to indicate a signal presence at inputs.
