VU and Peak Metering VU meter is a liar the equipment must have headroom to allow for peaks which the meter does not show Traditional analog consoles and peripherals such as compressors equipped with VU meters are usually aligned to 4 dBu so we recommend adjusting the digital system so 4 dBu or lower equals 20 dBFS with a sine wave alignment tone and an external analog voltmeter Then in operation watch your digital peak meters on your digital DAW and apparently as long as they do not go over 0 dBFS then the digital will not clip and neither will the EQ232P I said apparently because there 1s the hidden factor of the true peak overload described below Also during normal operation glance at the clip indicators on the equalizer as further confirmation that everything is safe especially if you are doing heavy EQ boosting Here 5 a tip Even if you do not have an analog voltmeter with a little care and time you can still calibrate your system achieve exactly the same analog headroom and matched levels using the clip lights of the EQ232P as an analog measuring tool and also reading the digital levels returning from the ADC Feed your DAC into the EQ232P set to flat and engaged and adjust the DAC output to ensure that the clip lights do not light with a full scale 0 dBFS sine wave from the DAC You can use the incoming meters from the ADC to determine how far your DAC 15 below Equalizer clipping You can even add a safety zone

5. Digital Section All digital circuits are 100 separated from the analog sections Additionally the digital signals are transmitted through optical connectors so that the digital section has no influence on the quality or noise floor of the sensitive analog circuits Memory cells are stored in non volatile EEPROM Memory This means that your custom saved states will not be lost even if power is disconnected from the unit The current power on condition is retained when the unit 1s manually switched off The USB type B connection lets you upload and download memory form the unit as well as use it as you would use a plugin in your DAW including automation and recall with session opening Power Supply The Power Supply of the Bettermaker EQ232P is located internally and is highly shielded from all analog sections to reduce potential noise and ensure the lowest noise floor possible The analog circuits use a separate power supply that is physically separated from the digital circuits with a magnetic shield The high quality toroidal power transformer ensures the Bettermaker EQ can be located close to other sensitive electronics without inducing additional noise Before plugging in the unit be sure the voltage selector switch is selected for your regional power requirements 110 230 Volt This switch is located on the inside of the unit However your unit has shipped with a sticker on the rear panel noting the voltage that has been set internally upon s

Shortcut to flat Double click on the Preset button of the EQ232P Hardware This basic overview of the hardware design approach of the Bettermaker EQ232P will help further your understanding of its sophisticated toolset and purist design Internal Routing For normal operation it is not necessary to access the interior of the EQ232P In the event of possible failure please see Part IX Trouble Shooting where many issues can be solved The analog and digital sections of your hybrid EQ are completely separate and isolated This keeps any control voltage for the digital section away from the sensitive analog components and lowers the overall noise of the unit Analog Section Great care and thought went into the development and implementation of the analog section of the Bettermaker EQ232P High quality capacitors are used throughout the analog path analog PCB s are totally separate and isolated both from the power boards and the digital section The use of precision metal film resistors minimizes the drift associated with traditional building processes This keeps each channel of the EQ within tight tolerances resulting in precise stereo tracking and thus a more natural open stereo spread with no phase shift between channels Exacting performance results in nearly unmeasurable differences between channels at all frequencies and levels perfectly symmetrical EQ1 and EQ2 boosts and cuts and 100 repeatable preset recalls
