ZONE4 Instruction manual ZONE4 Instruction manual ZONE4 Manual 1 2 Pre-Amplifiers Safety information • P lease check the carton box for any kind of damage on reception of the goods. In case of a damaged carton, please contact your dealer before opening the carton. • ! !!! Danger !!!! Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably to noise induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient amount of time. Therefore it is recommended that all persons exposed to equipment capable of producing high sound pressure levels, such as this amplifier, be protected by hearing protection while installing or operating this unit. • Read all documentation before operating your equipment. • Keep all documentation for future reference. • S ave the carton and packing material even if the equipment has arrived in good condition. • S hould you ever need to ship the unit, use only the original factory packing. • Do not spill water or other liquids into or on the unit. • M ake sure power outlets conform to the power requirements listed on the back of the unit. • D o not use the unit if the electrical power cord is frayed or broken. • H ave gain controls on amplifiers turned down during power-up to prevent speaker damage if there are high signal levels at the inputs. ZONE4 Instruction manual • D o not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such as a battery, mains source, or power supply, regardless of whether the amplifier or console is turned on or off. • P ower down & disconnect units from mains voltage before making connections. • D o not use the unit near stoves, heat registers, radiators, or other heat producing devices. • D o not remove the cover. Removing the cover will expose you to potentially dangerous voltages. • In case of mal-function this device should be serviced by qualified service personnel only. 3 4 Pre-Amplifiers Introduction Zone 4 professional preamp has 4 stereo line source inputs on RCA connectors plus 3 mono mic/line balanced inputs on euroblocks. All mic inputs feature individual sensitivity, level and tone control. Mic 2 and 3 inputs have switchable phantom power. Each mic signal can be assigned to any of the 4 available zone outputs.Microphone input 1 controls and connectors are available at the rear of the unit, featuring a balanced mic input with priority switch and zone assign preset dipswitches. If you need more flexibility and ease of installation, simply connect our Apart selective paging station MICPAT-4 instead, it will override the mic 1 zone assignments. Mic 2 and 3 inputs can be controlled and assigned via the front panel controls. In order to avoid any abuse by the end user, you can hide the microphone controls with the supplied cover plate. Zone 1 to 4 stereo outputs can be individually configured as mono or stereo outputs and are available on RCA connectors. Every zone has its own line input selector, bass and treble tone control and music level control. Every zone also has its own microphone mix level control. Music and mic mix can be muted/unmuted manually per zone by simply pushing the level knob. System integrators will be pleased to find a RS232 port at the back, allowing full control of the most important system parameters. If you need to control the zones locally, you can always add a wired remote, Apart model ZONE4R to any zone. Wiring is simple, using standard RJ45 connectors and CAT5 cable. Finally there is the IR input port. This port can be used to connect our optional PIR-REC infrared receiver. There is no infrared remote control available for the ZONE4 unit. We have added the infrared codes for those who want to program their universal infrared control unit. 5 ZONE4 Instruction manual Front panel 5 7 3 2 1 6 4 11 9 8 15 17 12 16 18 13 10 20 19 14 1. D isconnect paging led: this led is lit when you push the disconnect paging button ‘2’. 2. D isconnect paging button: push this button to disable the paging function. This can be convenient in case you want to avoid accidental paging and thus muting of the line inputs. Note that mic 2 and mic 3 are still active. The paging button(s) will not mute the music (or line signals). Mic 1 will be entirely disabled. 3. Z one assign dipswitches mic 2: with these dipswitches you can assign the mic 2 signal to zone 1 to 4. 4. Z one assign dipswitches mic 3: with these dipswitches you can assign the mic 3 signal to zone 1 to 4. 5. M ic 2 tone control: turn the knob to darken the tone (turn to the left) or to brighten the tone (turn to the right). 6. M ic 3 tone control: turn the knob to darken the tone (turn to the left) or to brighten the tone (turn to the right). 7. Mic 2 level control: turn the knob to the right to increase mic 2 6 Pre-Amplifiers level or to the left to reduce the level. 8. M ic 3 level control: turn the knob to the right to increase mic 3 level or to the left to reduce the level. 9. M ic signal/clip led: this led is green when a signal is present on mic 2 input and is red when the input is overloaded. Reduce the gain knob at the rear to avoid overload and distortion. 10. Mic signal/clip led: this led is green when a signal is present on mic 3 input and is red when the input is overloaded. Reduce the gain knob at the rear to avoid overload and distortion. 11. Zone 1 line input selector switches: use these switches to scroll through line input A to D. The selected input is shown in the display ‘12’ as A, b, C, d. 12. Multifunctional 7 segment LED display: this display shows the currently selected line input. When you change the mic or music level by turning the knobs 15 or 17, the actual level is shown in the display for a few seconds. 13. Lo tone control: push the + or – buttons to increase or decrease the bass tones in zone 1. This tone control has no influence on the mic tone control and will adjust the tone on line signals only. 14. Hi tone control: push the + or – buttons to increase or decrease the high tones in zone 1. This tone control has no influence on the mic tone control and will adjust the tone on line signals only. 15. Zone 1 music level control: turn this knob to adjust the zone 1 music level. If you push this button, the music will be muted. Pushing a second time will unmute the music signal in zone 1. This is indicated by led ‘16’. ZONE4 Instruction manual 16. Music mute led: this led lights up when the music in zone 1 is muted by pushing the ‘15’ knob or by activating paging. 17. Mic mix level control zone 1: turn this knob to adjust the zone 1 mic mix level. If you push this button, the mic mix signal will be muted. Pushing a second time will unmute the mic mix signal in zone 1. This is indicated by led ‘18’. 18. Mic mix mute led: this led lights up when the mic mix in zone 1 is muted by pushing the ‘17’ knob. Please note that this will not disable the paging function of the mics, in other words : if the microphone signal is muted, but when paging is activated, the music level will be muted also, unless you activate disconnect paging (button ‘2’). 19. On/off switch: flip this switch to turn the unit on or off. 20. Power led: this led is lit when the power is on. When the unit is set to stand-by via RS232, then this led will still be lit to indicate that mains power is still present. 7 8 Pre-Amplifiers Back panel 1 3 5 21 25 2 4 6 7 8 9 16 13 11 10 12 14 15 18 17 28 24 20 19 22 30 27 23 26 29 1.
