The chime function has priority over all channels, muting the channels 5-0 when the chime is activated.. Paging Microphone Volume Control The paging microphone volume is adjustable. Turn the level control anti clockwise to the lowest setting, or turn clockwise to adjust to the highest setting. When the paging microphone is activated, the mixer will must channels 5-0. 4. /Line Volume Control Each of the /Line volumes are adjustable. Turn the level control anti clockwise to the lowest setting, or turn clockwise to adjust to the highest setting. 5. Mode Switch The mode switch allows the installer to choose from either or Line level signal inputs. : Microphone level input with 00Hz high pass filter. Activate the to reduce stage rumble or to improve the intelligibility when using traditional 00V horn speakers. : Full range microphone level input. LINE: Full range line level input for use with audio sources such as CD players & radio tuners.. Output Level Indicator The output level indicator (VU meter) has three green LEDs, one amber LED and one red LED. During normal operation, the output meter should show only green LEDs. As the output reaches maximum, the amber LED will illuminate followed by the red LED to indicate +db over signal. 7. Master Zone LF/HF Controls During initial setup the high frequency and low frequency tone adjustments should be set to the zero point ( O'clock position). Turn the level control anti clockwise to reduce the high/low frequency tones, or turn clockwise to adjust the increase the high/low frequency tones. Adjustments should be made gradually to avoid any sudden changes to the audio output.. Master Zone Output Volume Controls The monitor output volume is adjustable. Turn the level control anti clockwise to the lowest setting, or turn clockwise to adjust to the highest setting. This is used to control the volume for the W ohm loudspeaker output on the rear panel of the zone mixer. www.cleveracoustics.co.uk ZM 0 Audio Mixer User Manual 5
Operating instructions 9. Power Indicator LED The Power LED will illuminate to indicate the zone mixer is powered on. If the power LED is not illuminated, check first the position of the on/off switch and then check the mains supply (including fuse). 0. Chime Output Select The chime function may be routed to output zone, output zone or both. Use the slide switch to select as required.. Signal Indicator LED Each of the input channels features an LED to give a visual indication if an input signal present on the relevant channel.. Output Zone Routing Selection The output of each individual input channel may routed to output zone, output zone or both. Use the slide switch to select as required.. Priority Selection The user may select from either /LINE, /LINE or /LINE4 to be highest priority. Using a small screwdriver, carefully remove the small protection cover to the right of /LINE in order to reveal the three way dipswitch. To switch priority ON for a given channel, move the dipswitch to the ON position. Note: Only one channel should be selected at any one time. 4. Master Zone LF/HF Controls During initial setup the high frequency and low frequency tone adjustments should be set to the zero point ( O'clock position). Turn the level control anti clockwise to reduce the high/low frequency tones, or turn clockwise to adjust the increase the high/low frequency tones. Adjustments should be made gradually to avoid any sudden changes to the audio output. 5. Power Switch On/Off control for the zone amplifier.. AC Mains Power Input 40V~50Hz AC mains voltage input. This product falls under CLASS and must have a protective earth connection at all times. 7. DC Power Input For connection to battery backup power sources, or for operation from leisure type batteries. The ZM 0 mixer may be used from 4V DC power sources. Care should be taken to ensure an inline fuse is fitted to the +ve supply and the power is connected with observing the polarity.. Balance Main Outputs Balanced, +4dBu mono outputs for each of the two output zones. Each zone output features a male XLR connector. www.cleveracoustics.co.uk ZM 0 Audio Mixer User Manual
Operating instructions 9. Record / Line Outputs Unbalanced, 0dBu mono outputs for each of the two output zones. Each zone output features a female phono (RCA) connector. The output volume for the record outputs is fixed and is not altered by the master volume control for the zone outputs. The white phono socket outputs zone, while the red phono socket outputs zone. 0. Line Inputs 7-0 Unbalanced, -0dBV (45mV) line inputs for channels 7-0 suitable for use with audio sources such as CD players or FM Tuners. Each stereo input features a pair of female phono (RCA) connectors, summed to mono internally. Selection of the Line input must be made via the front panel MODE selector switches.. /Line Inputs 7-0 /Line inputs 7-0 all feature balanced, mono audio inputs, switchable, with Low Cut or LINE. When used in either or with Low Cut mode, the mixer will provide 4V phantom power. To reduce stage rumble, the mixer features with Low Cut mode where a 00Hz high pass filter may be enable to help reduce background noise and increase intelligibility. For LINE input, the mixer features a pair of stereo phono sockets (summed to mono internally) for each of the input channels. To use the LINE input, use the selector switch on the front panel of the mixer.. /Line Inputs - /Line inputs 7-0 all feature balanced, mono audio inputs, switchable, with Low Cut or LINE. When used in either or with Low Cut mode, the mixer will provide 4V phantom power, selection is made via the switch on the front panel. To reduce stage rumble, the mixer features with Low Cut mode where a 00Hz high pass filter may be enable to help reduce background noise and increase intelligibility. To use the LINE input, use the selector switch on the front panel of the mixer.. Paging Microphone Input Dedicated input for the PM ZM 0 Paging microphone. Pin = Microphone +ve (hot) Pin = Microphone Ground Pin = Microphone ve (cold) Pin4 = Function Ground Pin5 = Priority Activate (short to Function Ground) Pin = Chime Activate (short to Function Ground) Pin7 = LED Power (4V DC) 4. Chime Interface To activate the chime function, a connection should be made between the two terminals by the way of a contact closure relay. The volume for the chime may be adjusted on the front panel of the unit. www.cleveracoustics.co.uk ZM 0 Audio Mixer User Manual 7
Operating instructions Power On/Off Procedure Prior to making any connection to the mains power or audio inputs/outputs, turn all level controls counter clockwise to the min position and all tone (equaliser) controls to the mid (zero) point. Switch on the zone mixer and any audio sources (MP players, CD players, Microphones etc) before powering the systems amplifier ON. The last product to be switched on should be the power/slave amplifiers to prevent any unwanted noise or potential damage to speakers or amplifiers. If you wish to power off the system, turn the amplifier s master volume control counter clockwise to the min position before switching the amplifier OFF before any audio sources are switched off. By following this procedure it will prevent acoustic shocks to the speakers or potential damage to system components. After connecting all audio sources and powering on the system, adjust the level of each audio input, select the zone routing in order to achieve the desired mix for each zone. Care should be taken to when adjusting microphone input volumes and the master volume, adjust both of these in small increment s to avoid feedback (howl around). The goal is to achieve a clear balance between music and voice ensuring announcements can be clearly heard. www.cleveracoustics.co.uk ZM 0 Audio Mixer User Manual
