ULTRAZONE ZMX8210

== In stereo mode (switch not pressed), the signal of the L input is sent to the LEFT bus, the R input is sent to the RIGHT bus and a mixed L/R signal is sent to the AUX bus.

{8} LEDs: These have the same function as the control {6}. In stereo mode, the LEDs show the summed level of the input signals L and R.

{9} LEVEL: This has the same function as the control {5}. In stereo mode, the control adjusts the volume level of the L/R signal.

[10]CH SELECT: This switch is used either to activate channel

7 or 8. The active channel is indicated by the glowing of the corresponding LED.

Main section

[11]MIC LOW CUT: This switch cuts low-frequency rumble below 100 Hz

[12]MIC MIX:This switch removes the signal of channels 1 – 6 from the remote control function, allowing only the output volume of channels 7/8 on the LEFT/RIGHT bus to be remote controlled.

When the switch is not pressed, the total volume of all chan- nels fed to the LEFT/RIGHT bus are remote controlled.

[13]RIGHT MUTE: This switch excludes the RIGHT bus from the Mute function. This is helpful when using the RIGHT and

LEFT buses for different zones (rooms).

== When the switch is pressed, the signal of channels 1 – 8, which is dependent on the signal level of channel 1, is muted on both the LEFT and RIGHT bus. This occurs when the input level of channel 1 drops below the speci- fied threshold value (THRESH {4}).

== When the switch is not pressed, only the LEFT bus is muted while the RIGHT bus continues to transmit a signal, provided the individual channels have been routed accordingly.

[14]EQ ON: The switch activates the equalizer [15] for the LEFT and RIGHT bus.

[15]LOW/LOW MID/HIGH MID/HIGH: This knob adjusts the boost/cut of factory-preset frequencies as follows:

== LOW: This boosts/cuts frequencies below 70 Hz by a maximum of ±15 dB.

== LOW MID: This boosts/cuts frequencies around 300 Hz by a maximum of ±15 dB.

== HIGH MID: This boosts/cuts frequencies around 3 kHz by a maximum of ±15 dB.

== HIGH: This boosts/cuts frequencies above 10 kHz by a maximum of ±15 dB.

Buses

[16]LEDs: When the CLIP LED lights up, attenuate the output level by using the LEVEL knob [17] to avoid clipping.

[17]LEVEL: This knob adjusts the output level of the bus outputs

OUT L, OUT R and AUX.

Mains

[18]POWER: The POWER switch powers up the mixer. The POWER switch should be in the Off position when connecting the unit to the mains.

++ To disconnect the unit from the mains, please pull the mains plug. When using the unit, make sure that the mains plug is readily accessible. When using the unit mounted in a rack, please make sure that you can easily disconnect the unit from the mains by using a plug or a circuit breaker on the backside.

++ Please note: The POWER switch does not entirely disconnect the unit from the mains when turned off. For this reason, disconnect the cable from the mains plug when the unit is not used for a long period.

SERIAL NUMBER: The serial number is found on the rear panel. It is required for online registration.

2.2 Rear panel

The BUS LINKS connector as well as the channel inputs 7 and 8 are unbalanced. The other PCB inputs and outputs are balanced. To use balanced connectors for unbalanced connections, insert a jumper wire between the ground pin (m) and the negative pin (-).

Fig. 2.3: Connections of the ZMX8210

[19]FUSEHOLDER/IEC power receptacle: The connection to the mains is established through an IEC connector. It meets all of the international safety certification requirements. A fitting power cord is included. When replacing the fuse, you need to use the same type.

++ Before you change the fuse, switch off the device and pull the plug to avoid electric shock or damage to the device.

[20]REMOTE: This connector is used for connecting components to remote control the ZMX8210.

== It is possible to connect a simple potentiometer to remote control the volume of the LEFT and RIGHT buses (see Chapter 3.1.3).

== Connect a push-button switch and two control diodes to remote control the CH SELECT switch {10} of channels

7 and 8 (see Chapter 3.1.3).

[21]BUS LINKS: Use this connector to link two ZMX8210s together to provide additional inputs (signals). The three output buses LEFT/RIGHT/AUX are linked together using the connector. The mute signal of the ZMX8210 which is set to be the master is also transmitted so that the mute function of the master is also able to mute the buses of the slave.

[22]SLAVE/MASTER: The switch places the ZMX8210 in the master or slave mode of operation.

When the switch

== is pressed, the ZMX8210 is placed in the slave mode of operation.

== is not pressed, the ZMX8210 is placed in the master mode of operation.

++ The ZMX8210 needs to be used in master mode when no additional units are connected!

++ When more than one ZMX8210 are connected, only one unit is allowed to be in master mode. The other units need to be placed in the slave mode of operation.

[23]AUX/OUT R/OUT L: Balanced signal outputs for buses AUX,

RIGHT and LEFT.
