Specifications - Solid State Logic SSL 18 User Manual

When using Outputs 7-8 and 9-10 for CV Control (HP A and HP B), be careful to first unplug any attached headphones from the
front panel outputs.
▪ When using these outputs with for CV control, we found that using High Impedance Headphones Mode or Line
Output Mode with unbalanced ticked generally provided the most reliable results.
▪ Remember Headphone level knobs are still affecting the signal and some experimentation may be required to find the
optimal level required for your connected equipment.
Best Practices & Safety
• NEVER send CV directly to your speakers (direct voltage can cause damage to your speakers).
• The CV Instrument device is only capable of calibrating oscillators that use bipolar voltage (+/-5V) for 1v/oct. tuning. However,
some digital oscillator modules exclusively use unipolar signals (+5V or above) for tuning. As a result, CV Tools will be
incompatible with these modules. If you are unsure whether this applies to the modules in your system, please consult the user
manual for the device.
• Remember - Eurorack signals are up to 5x louder than line-level audio! Before connecting your modular system to a digital audio
interface, be sure to reduce the signal down to line-level using a dedicated output module.
