9 UNPACKING AND INSPECTION Your equipment was packed carefully at the factory in a container designed to protect the unit during shipment. Nevertheless, we recommend making a careful inspection of the shipping carton and the contents for any signs of physical damage. Damage & Claims If damage is evident, do not discard the container or packing material. Contact your carrier immediately to file a claim for damages. Customarily, the carrier requires you, the consignee, to make all damage claims.
FIRST INSTALLATION RECOMMENDATIONS 10 FIRST INSTALLATION RECOMMENDATIONS 10.1 POWER SUPPLY CABLE A power supply cable of approx. 2 mt length is supplied with the device, which has a moulded IEC plug attached – this is a legal requirement. The type of plug for the power supply depends on the country in which it is delivered.
FIRST INSTALLATION RECOMMENDATIONS 10.3 FUSE REPLACEMENT The power supply socket has an integral fuse drawer containing the AC power fuse and a spare, both of the same value. BEFORE REPLACING THE POWER FUSE, MAKE SURE YOU HAVE THE RIGHT TYPE OF FUSE FOR THE VOLTAGE TO BE PROTECTED. USING WRONG FUSE TYPE WILL RESULT IN INSUFFICIENT PROTECTION. Make sure that the power is switched off and the power cable is disconnected from the equipment. Open the fuse drawer using a small blade screwdriver.
11 GENERAL EQUIPMENT DESCRIPTION 11.1 FRONT PANEL 1 GAIN control for signal applied to A input. Operating range: ±10 dB 2 GAIN control for signal applied to B input. Operating range: ±10 dB. In the GENIUS-ALM VERSION, this knob controls the level of MP3 Player 3 Audio Detector control section. It comprises three controls: THR (THRESHOLD), which sets the trigger level for the audio detector; TIME, which sets the counter frequency and a LED which flashes at every counter step.

GENERAL EQUIPMENT DESCRIPTION 8 ‘B’ BALANCED INPUT XLR female input pair (electronically balanced). They are used to connect the alternative (spare) audio source. If any balanced connection is possible, connect the cold pole (Pin 3) to the ground (Pin 1) on XLR connectors. Factory preset input impedance is 10 kΩ.
GENERAL EQUIPMENT DESCRIPTION 11.3 BLOCK DIAGRAM Pag.
BASIC AUDIO SETTINGS 12 BASIC AUDIO SETTINGS 12.1 INPUT IMPEDANCE SETTING Default input impedance is set at 10 Kohm. It can be altered to 600 Ohm, by placing Jumpers J 42 and J 43 for A input and J40 – J 41 (for B input) in the position shown in the figure. The Jumpers are located on the rear board, behind the respective XLR connectors. NOTE: THE INPUT B IS DISABLED ON GENIUS-ALM VERSION. 12.
THE AUDIO DETECTOR STAGE 13 THE AUDIO DETECTOR STAGE 13.1 HOW THE AUDIO DETECTOR WORKS Audio is monitored as a mono or a stereo signal. 4 Jumpers allow to choose which source will feed the Audio Detector stage (i.e. which source will be monitored by the Detector stage). Jumpers are J1, J2, J3 and J4 (see Block Diagram). By default, Jumpers J1 and J2 only are fitted (and thus Input A only is constantly monitored by the Detector).
THE AUDIO DETECTOR STAGE and then it begins to measure the ‘blank’ time on the basis on the internal Counter (in this case set as default for 16 cycles). The entire ‘blank’ time before switching will be calculated as the Hold time + 16 x Time Unit (where the Time Unit is adjusted by means of the Time trimmer on the Front Panel – see following Paragraphs). It should be noticed, Jumper J 21 and J 22 must be fitted in order to let the Spare source (Input B) appear on the Output.
AUXILIARY FUNCTIONS 14 AUXILIARY FUNCTIONS 14.1 MULTIPLAY The Multiplay is an oscillator which is used to apply subsequent pulses to external devices connected to the Remote Interface. The Multiplay starts when the Audio Detector remarks the blank longer than the set one (see Auto Detector) and it stops when the signal level rises over the threshold again. Every impulse lasts for about 1 second.
AUXILIARY FUNCTIONS 14.3 ADDITION OF A PILOT TONE TO INPUT B / MP3 BACK-UP SOURCE J11 . J12 It overlaps the 19 KHz @ –20dB to the Right channel of the B input / Mp3 Back-Up Source * It overlaps the 19 KHz @ –20dB to the Left channel of the B input. / / Mp3 Back-Up Source *.
AUXILIARY FUNCTIONS 14.5 THE ‘MIX’ OUTPUT MODE Closing the MIX input on the Remote Interface, the Genius will mix together Input A and Input B (instead of switching between them) and output their sum. 14.6 THE ‘RESET’ COMMAND As long as the Rest command is provided through the Remote Interface, the Audio Detector counter (see Section ‘ How the Audio Detector works’) is inhibited and thus possible audio blanks are not detected. 14.

INTERFACE AND PORT DESCRIPTION 15 INTERFACE AND PORT DESCRIPTION 15.1 REMOTE INTERFACE DESCRIPTION 25-pin female Interface connector provides 4 optoinsulated “trigger” inputs, 1 optoinsulated signalling (for ‘Manual’ mode) and it connects 3 relays associated to Audio Detect switching and to B Input selection. The interface presents also a + 15 Vdc and – 15 Vdc rails to be used for optocoupler polarization in event of lack of external control voltage.

FAQS AND ADDITIONAL NOTES ON BACK-UP MP3 PLAYER 16 FAQS AND ADDITIONAL NOTES ON BACK-UP MP3 PLAYER Featuring an optional, internal MP3 reader (see GENIUS-ALM version) as back-up audio source, the GENIUS allows to overcome any ‘blank’ or silence time in radio broadcasting. As soon as main audio lacks on INPUT ‘A’, the GENIUS waits for the pre-set ‘silence time’ before switching over the internal Mp3 Back-Up audio source. When main audio resumes, the GENIUS switches back over the INPUT ‘A’ source.
