PRODUCT BROCHURE

A focused way to shape the whole picture.

Adjust the foundation, bring the middle into focus and open the top end. Precision EQ keeps four band sections visible on each side, with numerical readouts and repeatable steps for revisiting a decision.

Start here

1. Insert the EQ on a stereo track or bus. Begin with a neutral setting and comfortable headroom.
2. Choose Stereo and link the corresponding bands when you want the same change on both channels.
3. Select a frequency and bandwidth, then try a small gain adjustment. Turn a band’s IN off to hear its contribution.
4. Enable Gain Match, allow a few seconds to settle, and compare using Bypass. Use A/B/C to keep alternate ideas close.
5. Save a named user preset when the setting is useful. Use Output to set the final level.

Frequency, gain and bandwidth

Each channel has Low, Low Mid, High Mid and High sections. Drag a knob vertically, scroll for one step, or hold Shift for slower adjustment. Double-click resets that control. Frequency and gain use 21 positions; gain spans −8 to +8 dB with finer steps around zero.

The bandwidth selector offers Shelf and five bell settings labeled 4, 6, 9, 14 and 20 REF. In this build, the bell Q values are 0.35, 0.5, 0.75, 1.2 and 2.0 respectively. REF labels are provisional reference markings, not calibrated hardware bandwidth measurements. Shelf applies a low shelf in the first two bands and a high shelf in the last two.

At lower sample rates, the engine caps frequency internally at 45% of the sample rate. For example, the cap at 44.1 kHz is 19.845 kHz; a higher displayed selection does not create an ultrasonic center frequency beyond that cap.

IN, LINK and SOLO

IN enables that EQ band. LINK mirrors edits made in the interface between corresponding bands; enabling it copies the clicked side to its partner. LINK ALL copies the left settings to the right and enables all four links. Host automation addresses channels independently.

SOLO auditions a band-pass signal around the selected frequency; it is not a delta of the EQ change. When any band is soloed, only soloed bands are heard, and a channel with none soloed is silent. Turn Solo off before judging the full mix.

Stereo and Mid/Side

STEREO treats the two banks as left and right. M/S treats them as Mid and Side, then converts the result back to stereo. Mid represents the center component; Side represents the difference between channels. Keep changes modest and check the full stereo mix after editing either component.

Balance, Output and meters

Balance adjusts the final left/right level relationship over a −1 to +1 dB range. Positive values favor the right; negative values favor the left. Output provides −5 to +5 dB of final trim. Both operate on the decoded stereo output.

The L/R meters show output peak activity in dBFS. They are not LUFS or true-peak meters. Use a dedicated meter and limiter when checking final delivery levels; this EQ does not provide a protective output ceiling.

Gain Match, Bypass and comparisons

Gain Match applies slow RMS compensation before Output trim, with approximately ±12 dB available. Allow several seconds for it to settle. Solo returns its target compensation toward unity. Bypass lets you compare against the unprocessed signal.

A/B/C holds three comparison states in the session. Undo and Redo revisit parameter edits. Save a user preset when you want a reusable setting outside that session.

Preset browser

LOAD opens the browser; SAVE opens it ready to name a new preset. Use search and categories to narrow the list. Single-click selects a row; double-click or Load recalls it and closes the browser after a successful load. The star marks favorites. Rename and Delete apply to user presets; factory presets remain protected. Click outside the browser or use Close to dismiss it.

User presets are stored under Library/Application Support/Shark Plugs/Precision EQ/Presets in your macOS home folder. Deleted user presets move to the preset Trash folder. The Guest Engineers category contains fictional Shark-created concepts and does not imply a real engineer’s approval.

Appearance and window size

Click the central logo for Black → Silver → Rustic Blue → Rustic Green. Theme changes preserve your sound settings. Open the hamburger menu for zoom, manual and About/Credits. Normal 100% size is approximately 1395 × 635 logical pixels; zoom choices run from 60% to 133%. Theme and window size are recalled with the session.

Click the small heart-and-shark badge for “Made with love. Thanks for listening.” It is a cosmetic thank-you and does not change the sound.

If something sounds unexpected

Check Solo first if a channel disappears. Check IN if a band seems inactive. If matching takes a moment, allow Gain Match to settle. If a linked automation move affects only one channel, automate both channels explicitly. Use Bypass and a neutral preset to isolate an unexpected tonal change.

Current release status

This guide describes the development build, including the meter artwork cleanup. Precision EQ uses an original digital filter engine; measured hardware matching and final release validation remain in progress. AU and VST3 are the project targets. Final supported systems, customer installers and purchase options will be published after release testing.
