1. CONTROL I6 User s Manual Version 1 5 English Safety Instructions Mro molid All safety and operating instructions should be read before the equipment is installed and operated We recommend that installation be carried out by an authorised mobile electronics installation company Please contact your local ALTO Mobile distributor for a list of authorised installers in your country To reduce the risk of electric shock and potentially damaging the equipment do not disassemble the product No user serviceable parts inside refer servicing to qualified personnel The equipment should be protected from moisture and rain especially if mounted in the vehicle s trunk area or any location that may be susceptible to water ingress The equipment should be situated so that its location or position does not interfere with its proper ventilation For example the product should not be situated under carpeting or in a totally sealed enclosure Trunk mounted equipment amp racks should be well ventilated using forced air cooling fans if necessary The equipment should be situated away from heat sources such as engine exhaust systems and radiators This product is designed for vehicles with a 12 VOLT NEGATIVE GROUND electrical circuit This product must not be used in vehicles that use a 24 Volt supply or a positive ground electrical circuit Great care must be taken when wiring the product to the vehicle s electrica2. Ground terminals connected correctly Is the Ground cable properly attached to the chassis of the vehicle or to an existing ground point that is known to be OK No Sound Adjust the level of the Input Gain Controls Adjust the level of the Output Gain Controls Are the Input and Output signal cables correctly connected If there is only sound from one channel swap the Left and Right channel Input cables at the CONTROL 16 if the fault moves to the other channel then the fault is with the cable or source unit If the fault remains in the same channel swap the Left and Right channel Output cables at the CONTROL16 If the fault still remains on the same speaker then the fault is with a cable or a unit after the CONTROL16 power amplifier active crossover or the speaker Check gain controls on those units and any input switching options If the fault moves to the other speaker then the CONTROL16 may be faulty leave it installed in your system and return to your dealer so that they can check it Distorted Sound or Low Volume Adjust the Input and Output Gain Controls of the CONTROL16 and the Input Level Controls of the power amplifier and or active crossover or additional processor where applicable Check if the amplifier has a built in crossover network is it switched correctly Your ALTO Warranty To be protected by this warranty the buyer must be able to produce a numbered machine printed sales receipt original only accepted no
3. The Output Volume set here can be stored as one of the custom preset parameters Heavy equalization can cause considerable variation in output level when switching from one preset to the next This allows you to set the same overall level while maintaining very different tonal contours Can also be used as a master gain control For example for safety you may want to limit the maximum output level set by the panel mounted rotary gain controls Mro molile Parameter Menus Load Preset Store Preset Allows you to store and recall the factory and custom presets When storing a custom preset use the UP DOWN and ENTER keys to scroll through the alphanumeric character set and name your new preset Equalizer Flat This command will force all the filters to their flat position To help avoid accidental resetting of the filters you are requested to confirm your choice with the request Are you sure on the display Press ENTER or ESC Bypass System Allows the signal to pass through the device unprocessed Warning This will bypass ALL functions set including the High Pass filter To come out of Bypass mode press the ENTER or ESC keys View EQ Filter This allows you to quickly review the current settings of all the parametric filters frequency gain and bandwidth Use the UP DOWN keys to scroll through the filters Factory Presets Dro molle The CONTROL16 offers 16 factory preset curves and 48 user definable preset memory lo
