COMPLIANCE This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by Intellijel Designs, Inc. could void the user’s authority to operate the equipment.
INSTALLATION This module is designed for use within an Intellijel-standard 1U row, such as contained within the Intellijel 4U and 7U Eurorack cases. Intellijel’s 1U specification is derived from the Eurorack mechanical specification set by Doepfer that is designed to support the use of lipped rails within industry standard rack heights. Before Your Start Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power supply.
You can use a tool like ModularGrid to assist in your planning. Failure to adequately power your modules may result in damage to your modules or power supply. If you are unsure, please contact us before proceeding. Installing Your Module When installing or removing a module from your case always turn off the power to the case and disconnect the power cable. Failure to do so may result in serious injury or equipment damage.
Once connected, the cabling between the module and power supply should resemble the picture below: Before reconnecting power and turning on your modular system, double check that the ribbon cable is fully seated on both ends and that all the pins are correctly aligned. If the pins are misaligned in any direction or the ribbon is backwards you can cause damage to your module, power supply, or other modules.
FRONT PANEL Inputs & Outputs [1] CH 1 input: The input is DC coupled and accepts signals between -10V and +10V. [2] CH 2 input: This input, like CH 1, is DC coupled and accepts signals between -10V and +10V. [3] CH 1 output: The signal appearing at the CH 1 input jack is normalled to the CH 1 output jack, so signals pass unimpeded through the Zeroscope 1U. This allows you to monitor signals without needing to re-patch or use signal multipliers.
BASIC OPERATION In its basic mode, Zeroscope 1U displays the waveforms for both CH 1 and CH 2, and gives you control over the display height of these two waveforms plus their displayed periodicity. 1. Connect CV or audio signals to either or both the CH 1 and CH 2 inputs. Both inputs are DC coupled and accept signals between -10V and +10V. Either can serve as a trigger source, configured to detect either the rising or falling edge of the waveform (as described later in the Trigger Source discussion).
ADVANCED OPERATION Zeroscope 1U offers several advanced display and triggering options, located within an Advanced Settings menu. 1. Long-press (>1 sec) the encoder to open the Advanced Settings menu. A small menu of options appears to the right of the display. 2. Turn the encoder to select and highlight which of six Advanced Settings options you wish to edit. There are six options accessible in this menu.
Using Tune Mode Tune Mode displays CH 1 and CH 2 frequencies either by number of cycles-per-second (Hz) or by Note Name. Once in Tune mode, simply press the encoder to toggle between the two display options. NOTE: The input signal must be at least +2V in order for the pitch detector to work. Hz Display The top line displays the frequency (in Hz) of the signal appearing at CH 1, and the second line displays the frequency of the signal appearing at CH 2.
Reference Pitch and Averaging Time Both the Hz Display and the Note Name Display have two additional options at the bottom of the scope: ref and avg. ref This displays the reference pitch used by the tuner (which displays the number of Hz to which the A above middle-C is tuned). Most devices default to 440Hz, but other standards are sometimes used. avg This displays how long the Zeroscope spends averaging out frequency variations before it recalculates and reports a new note name.
Trigger Source With this option selected, push-turn the encoder to select how you want to trigger the Zeroscope.
CH 1 Offset With this option selected, push-turn the encoder to set a display offset for the CH 1 waveform. Waveforms can be offset ± 10V (-10000µV - +10000µV). Offsetting waveforms is particularly useful if you want to display CH 1’s waveform above (or below) CH 2’s waveform. For example, assume CH 1 and CH 2 are both typical ± 5V waveforms. If you set both the CH 1 and CH 2 Display Values to 5.0 V per division, then each waveform is ½ the entire height of the scope.
Screen Saver In order to extend the life of your screen, Zeroscope 1U features a built-in screen saver, which turns off the display after a user-definable length of time. If the screen has turned off, simply press or turn the encoder to turn the display back on. To set the amount of time until the screen saver dims the screen: 1. Long-press (>1 sec) the encoder to open the Advanced Settings menu. A small menu of options appears to the right of the display. 2. Turn the encoder to select the SCOPE option. 3.
