Frequently Asked Questions
The Chandler Limited Curve Bender Mastering EQ is worth it if you want an EQ that adds character and weight to your mix bus or master, not just surgical correction. It's the only authentic emulation of Chandler Limited's Curve Bender, a mastering EQ built on the circuit of a classic British console. You get the thick lows, forward mids, and smooth highs of inductor-based filters, plus plug-in-only extras like Mid/Side processing and Channel Linking.
The Chandler Limited Curve Bender Mastering EQ colors your sound as it shapes it, thanks to modeled inductor-based filters. Many mastering EQs aim to be transparent. The Curve Bender goes the other direction, with broad, musical curves that add density and attitude to a mix, even when you push it hard.
An inductor-based EQ like the Chandler Limited Curve Bender Mastering EQ uses coils of wire, called inductors, inside its filter circuits to shape frequencies. Inductors add their own subtle coloration as audio passes through, which is where the classic "fat low end, smooth top" sound comes from. The Curve Bender plug-in models that behavior, so your boosts sound rich and rounded instead of thin or brittle.
The Chandler Limited Curve Bender Mastering EQ runs on UAD-2 DSP, so you need an Apollo audio interface or a UAD-2 DSP Accelerator (Satellite or PCIe card). All of the processing happens on the hardware's onboard DSP, not on your computer. The Curve Bender is a detailed model, so if you plan to run several instances on a big session, an Apollo or accelerator with more DSP chips gives you extra headroom.
The Chandler Limited Curve Bender Mastering EQ expands the original British console EQ's nine fixed filter points to 51. It also adds more gain options, a slightly more flexible Q, extra high-pass and low-pass filters, and Mid/Side capability. Those upgrades turn a classic tracking-console EQ into a full mix bus and mastering tool that still carries the original's tone.
The Chandler Limited Curve Bender Mastering EQ sounds fat and colorful, with thick low end, slightly aggressive mids, and smooth highs. That's the signature of its inductor-based filters, and it's why the Curve Bender adds weight and air to a mix even with modest settings. Think of it as the EQ you reach for to give a track personality, not to stay invisible.
Yes, the Chandler Limited Curve Bender Mastering EQ is built to handle big boosts without turning harsh. Its broad curves spread gain gently across a range of frequencies rather than spiking a narrow band, so adding top-end air or low-end weight to a master stays smooth. That makes it forgiving when you're still learning and dependable when you're on a deadline.
Yes, the Chandler Limited Curve Bender Mastering EQ is the only authentic emulation of Chandler Limited's Curve Bender hardware. Our modeling captures the behavior of the inductor-based filter circuits that define the hardware's tone. Engineers who own the hardware use the plug-in to take that same sound onto a laptop rig and match it with their analog chain back in the studio.
Yes, the Chandler Limited Curve Bender Mastering EQ runs on both macOS and Windows, including Apple Silicon Macs, whenever a supported Apollo interface or UAD-2 accelerator is connected. Your UAD-2 plug-in licenses follow your UA hardware, so the Curve Bender goes with your Apollo from one computer to the next. Supported operating system versions are listed in our current system requirements.
The Chandler Limited Curve Bender Mastering EQ works in any DAW that supports VST3, AU, or AAX plug-ins, and in the LUNA Digital Audio Workstation on both Mac and Windows. Because it runs on your UA hardware's DSP, it behaves the same way no matter which host you mix in. You can also load it inside the Apollo Console app.
No, the Chandler Limited Curve Bender Mastering EQ runs on the DSP inside your Apollo or UAD-2 accelerator, not on your computer's CPU. That keeps your processor free for virtual instruments and native plug-ins in a busy session. It's especially handy on the mix bus, where a detailed EQ model sits on top of everything else you're running.
The Chandler Limited Curve Bender Mastering EQ is designed first and foremost for the mix bus, where it adds air, depth, and inductor-based color to the whole mix. A classic move is a gentle low boost for weight and a high boost for air, with Channel Linking keeping both sides of the stereo image matched. Because the curves are broad, small moves go a long way.
Yes, the Chandler Limited Curve Bender Mastering EQ works on drum buses, vocal buses, and individual tracks, not just masters. On drums it adds punch and old-school attitude, and on vocals, acoustic guitar, synths, and electric piano it brings a forward, colorful presence. If a source sounds a little flat or polite, the Curve Bender is a quick way to give it some spice.
Yes, with an Apollo interface you can load the Chandler Limited Curve Bender Mastering EQ in the Console app and hear it in realtime at near-zero latency while you record. You can monitor through it only, or print the processing straight to your DAW. It's a nice way to shape a vocal or acoustic source on the way in, so your tracks already sound finished when you start mixing.
Yes, DSP-based UAD plug-ins like the Chandler Limited Curve Bender Mastering EQ are still worth buying for anyone working with an Apollo or UAD-2 accelerator. DSP keeps detailed analog modeling off your CPU, and on Apollo it lets you track through plug-ins in realtime at near-zero latency with the processing handled by the interface itself. Your plug-in licenses also stay with your UA hardware, so the library you build moves with you from computer to computer.
The Chandler Limited Curve Bender Mastering EQ currently runs as a UAD-2 DSP plug-in, which requires an Apollo audio interface or UAD-2 accelerator. UAD native plug-ins run on your computer's CPU with no UA hardware required, and UA continues to bring classic titles from its catalog to native format. If you're working without UA hardware today, the UAD native plug-in library offers a range of EQs and mastering tools that run on any supported Mac or PC.
The Chandler Limited Curve Bender Mastering EQ pairs naturally with the Chandler Limited Zener Limiter, which comes from the same console-inspired design family, and with UAD mastering compressors like the Shadow Hills Mastering Compressor Class A. A common chain puts the Curve Bender first for tone shaping, then compression, then limiting. Together they give you a complete, analog-flavored mastering path inside your DAW.
Yes, the Chandler Limited Curve Bender Mastering EQ is approachable if you’re a newer producer because its bands use fixed, musically chosen frequency points instead of endless sweeps. You pick a frequency, dial in a boost or cut, and the broad curves keep the result smooth. That makes it easy to learn by ear, while the extended controls give experienced engineers plenty of precision.
