How To Use - Synq PE-900 Bedienungsanleitung

ENGLISH
4. PROTECT LEDS: The protection LED is on when the speakers are disconnected from
the amplifier. This occurs in the following situations:
 During the first seconds after switching on the amplifier.
 When the temperature of the power stage becomes too high.
 In case of a technical defect: DC protection!
 While switching the amplifier off, the "protect led" turns on for a short time.
5. SIGNAL LEDS: these LEDs indicate that a music signal is present at the inputs.
6. LIMIT LEDS: Turn on just before the maximum, distortion free, output level of the
amplifier. They indicate that the internal limiter starts working. The limit LEDs may turn
on shortly from time to time but they may certainly not turn on for longer periods. In this
case you have to turn the output level down!
7. MAINS SWITCH: Used to turn the amplifier on and off. A few seconds after switching
on the amplifier it is ready for operation.
FUNCTIONS
(REAR)
8. FAN & VENTILLATION HOLES: during its operation the amplifier produces heat that
must be dissipated. The fans inside the amplifier must be able to evacuate the heat in
the most effective way. Therefore is it very important not to cover any of the ventilation
openings as this may result in overheating.
9. XLR/JACK inputs: You can connect these balanced inputs
to balanced and unbalanced line level audio sources:
 Balanced
source: Use good
balanced audio cables.
Wiring of the XLR connector:
PIN1: GND PIN2: pos+ PIN3: neg-.
Wiring of the JACK connector:
Sleeve: GND TIP: pos+ RING: neg-.
 Unbalanced source: Use good quality XLR/cinch or
JACK/cinch audio cables.
Wiring of the XLR connector:
PIN1: GND PIN2: pos+ PIN3: GND (connect to PIN1)
Wiring of the JACK connector:
Sleeve: GND TIP: pos+ RING: GND (connect to
sleeve)

10. XLR LINK outputs: in several cases you need a
lot of power that can't be produced by only 1
amplifier. In these cases the link outputs are
used to daisy chain the inputs/outputs of several
amplifiers. The wiring if these male XLR outputs
are identical to the inputs.
11. INPUT SENSITIVITY switch: With this switch
you can perfectly adapt the input sensitivity of the amplifier: 0,775V; 1,0V or 1,44V.
12. OPERATION MODE switch: Used to set the operation mode of the amplifier. The
most common operation mode is "stereo". If you need more power, you can operate
the amplifier in bridge mode. Refer also to point 3 for more information.
13. L+R SPEAKON OUTPUTS: use these Speakon
cabinets in stereo or mono mode. Wiring of these connectors is as follows:
 POS(+) = Speakon connector PIN1+ and PIN2+
 NEG(-) = Speakon connector PIN1- and PIN2-
14. BRIDGE SPEAKON OUTPUT: use this Speakon
connector to connect your speaker cabinet in bridge
mode. Refer to points 3 and 12 for more information.
Wiring of this connector is as follows:
 POS(+) = Speakon connector PIN1+ and PIN2+
 NEG(-) = Speakon connector PIN1- and PIN2-
15. MAINS input: When all audio cables are connected, you can connect this cable to an
earthed mains outlet.
16. RESET button: this amplifier uses an automatic fuse. When the fuse is blown, simply
press the button to rearm it.
17. GROUND LIFT switch: In some cases nasty hum noises can occur due to ground
loops in your setup. Setting the Ground lift switch to the position "lift" breaks the ground
loop between the amplifier and the chassis grounds of various other components in
your setup. As a result the hum noises disappear.

HOW TO USE

STEREO OPERATION:
 Connect the audio signal to the inputs (9)
 Set the operation mode switch (12) to "stereo"
 Connect the matching speakers to the L+R Speakon
outputs (13)
 Make sure the mains voltage matches 230Vac before
connecting the mains cable to the earthed wall socket.
 Set both input gains (2) to zero
 Make sure there's a music signal at the input
 Turn the amplifier on (7)
 Adjust the input gains (2) to the desired level
BRIDGE OPERATION:
 Connect the audio signal to the left input (9)
 Set the operation mode switch (12) to "bridge"
 Connect the matching speaker(s) to the Bridge Speakon
output (14)
