Mosaic Line In
Stereo line-to-modular input converter with shared +18 dB gain.
8 HP Eurorack module
Line In is an unbalanced stereo line-to-modular level converter from Mosaic's 1U tile lineup. Two 1/8" inputs accept consumer or pro line-level audio (-10 dBV / +4 dBu sources such as desktop synths, audio interfaces, drum machines, smartphones via adapter), and a single shared LEVEL attenuator drives both channels with up to +18 dB of gain so the resulting signal sits at the roughly 10 Vpp Eurorack standard. The two outputs feed the rest of the rack, letting you process external instruments through filters, effects, and VCAs alongside in-rack signals.
Features
- Stereo unbalanced line input (two 1/8" TS jacks)
- Single shared dual-gang LEVEL knob drives both channels
- Up to +18 dB of gain to bring line-level (-10 dBV / +4 dBu) up to ~10 Vpp modular level
- Fully counter-clockwise = silent (-infinity dB)
- Two independent modular-level outputs (no internal summing)
- No normalling between L and R — channels are fully parallel mono paths
- 8 HP wide, 38 mm deep, fits any 1U row
- Ships in Intellijel 1U format; Pulp Logic replacement panel available from Mosaic
- Color-coded panel: green ovals = audio (per Mosaic's house color guide)
- Low power draw: 23 mA +12V, 21 mA -12V, 0 mA 5V
- Compatible with desktop synths, drum machines, audio interfaces, phones, tape machines
- Available in white-panel and black-panel cosmetic variants
Controls & Jacks (5)
- In Left — Line-level audio input for the left channel
- In Right — Line-level audio input for the right channel
- Level — Shared gain attenuator: -infinity dB (silent) at fully CCW to +18 dB at fully CW. Drives both channels equally up to modular level.
- Out Left — Modular-level audio output for the left channel after gain
- Out Right — Modular-level audio output for the right channel after gain
How-To Guides
- Bring a desktop synth into the rack
- Run a phone or laptop into the rack
- Vocals (with an outboard mic preamp first)
- Re-amp a tape loop into a feedback patch
- Sampling source for a rack sampler
