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.
SYSTEM OVERVIEW Use the Stereo Line In 1U system to bring external audio into your modular system for processing. The system works with balanced +4 dBu professional audio products and with -10dbV unbalanced gear. The Stereo Line In 1U system comprises two components: [1] The Stereo Line In 1U module: A ribbon cable connects this module to either the Stereo In Jacks 1U module, or to a compatible Intellijel case with built-in ¼” jacks.
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 You Start Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power supply.
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. Ensure the 10-pin connector on the power cable is connected correctly to the module before proceeding. The red stripe on the cable must line up with the -12V pins on the module’s power connector. Different modules use different ways to indicate the -12V pins.
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.
Connecting a Stereo Line In 1U to a Stereo In Jacks 1U The Stereo Line In 1U module ships with a ribbon cable for connecting to a pair of ¼” TRS audio jacks — either those built-in to the 2nd generation Audio Jacks Board installed in Intellijel 7U cases; an Intellijel Palette case, or those contained within the separately available Stereo In Jacks 1U module. To connect the Stereo Line In 1U module to the Stereo In Jacks 1U module: 1.
Connecting a Stereo Line In 1U to the ¼” Jacks on a 7U Case The Stereo Line In 1U module ships with a ribbon cable for connecting to a pair of ¼” TRS audio jacks — either those built-in to the 2nd generation Audio Jacks Board installed in Intellijel 7U cases; an Intellijel Palette case, or those contained within the separately available Stereo In Jacks 1U module To connect the Stereo Line In 1U module to the jacks installed in your 7U case: 1.
Connecting Two Stereo Line In 1U Modules to a 7U Case You can connect a second Stereo Line In 1U module to the other 6-pin connector on the Audio Jacks board, giving you four audio inputs in a 7U case. 1. Using the ribbon cable supplied with the Stereo Line In 1U module, connect it to one of the two keyed 6-pin connectors on the 2nd generation Audio Jacks Board. 2. Connect the other Stereo Line In 1U module to the remaining keyed 6-pin connector on the Audio Jacks Board.
Connecting a Stereo Line In 1U to a Palette Case’s ¼” Jacks The Stereo Line In 1U module ships with a ribbon cable for connecting to a pair of ¼” TRS audio jacks — either those built-in to the 2nd generation Audio Jacks Board installed in Intellijel 7U cases; an Intellijel Palette case, or those contained within the separately available Stereo Out Jacks 1U module. To connect the Stereo Line In 1U module to the jacks installed in your Intellijel Palette case: 1.
FRONT PANEL (Stereo Line In 1U) Controls [A] INPUT GAIN L Scales the input signal level, which arrives via a ¼” jack (ie. a Stereo Line In 1U module, a Palette case, or a 7U case with 2nd generation Audio Jacks board) connected to the rear of this module. Fully counterclockwise, the input is completely attenuated. Set fully clockwise, +15dB of gain is applied to the input signal before sending it to the OUT L [1] jack.
Inputs & Outputs [1] L Output This jack carries the amplified, eurorack-level signal of an external signal patched into the connected device’s left ¼” input jack (i.e, a Stereo In Jacks 1U module; a Palette case; or an Intellijel 7U case with a 2nd generation Audio Jacks Board). The level of this signal is governed by the INPUT GAIN L knob [A], and can be monitored using the corresponding LEVEL L LEDs [C].
FRONT PANEL (Stereo In Jacks 1U) Inputs & Outputs [1] LINE IN (L) An external signal patched into this ¼” TRS jack is passed through to the left channel of a connected Stereo Line In 1U module, where it’s amplified to eurorack levels and made available to other eurorack modules via the left ⅛” output on the Stereo Line In 1U module. This input supports both professional, balanced +4 dBu equipment and prosumer, unbalanced -10 dbV level gear.
