1 Safety Instructions
lease read carefully the next safety instructions.
1. Keep these instructions for future reference
2. Locate the apparatus at places nearby power socket for quick power
disconnection. Avoid places where the equipment can be an obstacle.
Disconnect the AC power supply before cleaning the equipment.
3. This appliance shall not be exposed to dripping or splashing water and that no
object filled with liquid shall be placed on the apparatus. Do not use any liquid
or spray detergent on the equipment for cleaning purposes. This appliance
should not be exposed to moisture.
4. Do not place any lit candles or similar objects on top of the apparatus.
5. Set up the equipment on a safe surface to avoid falls and damages.
6. The covering grill provides air convection. DO NOT COVER THE GRILLS. A
gap of 5 cm should be left around the perimeter of the apparatus to allow
correct ventilation.
7. The equipment shall never be opened. For safety reasons, please contact
qualified personnel.
8. The apparatus should be connected to ground for protection.
9. Ask the technician to inspect the equipment if any of the next situations occur:

5 Speaker wiring.
5.1 Low impedance speaker connection. 4 Ω and 8 Ω
In order to connect conventional 4Ω and 8Ω speaker systems, connect positive
terminal of the speaker (+) to 4Ω or 8Ω terminal. Connect the negative side (-) to COM
terminal.

5.2 High impedance speaker connection. 70/100V
In order to parallel connect high impedance speaker systems (70/100V),
connect the positive side of the speaker (+) to 70/100V terminal. Connect the negative
side (-) to COM terminal.
5.3 Incorrect speaker connection.
CAUTION: 70/100V output lines should never be used simultaneously with the low
impedance output, otherwise the equipment could be seriously damaged.

6 Operating Overview
1. ower On:
ower connection: 110 - 240V AC 50/60Hz. ress the ON/OFF switch on the front panel.
2. hantom ower:
This unit allows phantom power for the first microphone input. To enable it you must
activate the corresponding switch on the rear panel.
3. Gain control input:
To adjust the gain of the inputs, the QX series features a potentiometer per input channel,
located on the rear panel. This potentiometer allows a dynamic range of 44dB.
4. riority control:
riority adjustment of the sources can be done by using the switch "Talkover" on the rear
panel for channel 1. QX60 has three priority levels :
(1) riority input (Tele- aging)
(2) Notification tone and input 1: If several of these inputs are active, the signal
will mix them.
(3) No priority: All inputs without priority will enter mixed.
