Rolls RA62c 6-Channel Headphone Amplifier, Per-Channel Direct Inputs, 1U

Rolls RA62c: Six High-Power Cue Mixes With Per-Channel Direct Inputs

The Rolls RA62c is a 6-channel headphone amplifier that delivers six loud, independent stereo cue mixes in a 1U rack, with a Direct Input on every channel for personal monitor mixing. It exists for tracking and broadcast rooms where each performer needs not just their own level but their own blend of the main mix and a second source. With nearly 2 watts per channel into 32 ohms, it drives in-ear monitors and demanding headphones to full volume with ease. Balanced XLR, RCA, and 1/4-inch main inputs let it connect to any console. For a studio that needs real cue-mixing power rather than a simple headphone splitter, the RA62c is built to do the job.

Six Channels of High-Current Amplification

The RA62c provides six stereo headphone channels, each delivering 972 mW per side and 1944 mW per channel into 32 ohms with up to 20 dB of gain. That high output current drives in-ear monitors, high-impedance studio headphones, and everything in between to a strong, clean level. Because each channel amplifies independently, one performer cranking their mix never robs another of volume or headroom. Twelve 1/4-inch and six 1/8-inch output jacks mean every station connects however the performer's headphones are terminated. For a full band tracking at once, that per-channel power is what keeps every set of cans loud and clear over the room.

Per-Channel Direct Inputs for Personal Mixes

Every channel has its own Direct Input, letting each performer blend a second stereo signal into their personal mix alongside the main feed. This is the RA62c's standout feature: a singer can add more of their own vocal, or a bassist more of the click, without changing anyone else's mix or tying up the console. The Direct Input sums a local source into just that one channel, so six performers can each shape their own monitor blend. That capability turns a headphone amp into a genuine personal-monitoring system. For a session where players ask for different things in their cans, those per-channel Direct Inputs solve the problem without endless console tweaking.

Flexible Cue Mixing With Mono/Stereo Switch

Each channel includes a pan control followed by a Mono/Stereo switch, giving flexible control over how the cue mix is placed and summed. Positioning the Mono/Stereo switch after the pan lets a performer collapse their mix to mono or keep it in stereo after setting the balance, which suits both in-ear and over-ear monitoring preferences. Some performers focus better on a centered mono cue, while others want the full stereo image; the RA62c serves both per channel. That routing detail is the kind of feature engineers appreciate when dialing in individual monitor feeds. For precise, personalized cue mixing, the pan-then-switch layout gives each channel real control.

Professional Balanced and Unbalanced Inputs

The RA62c accepts main inputs on balanced XLR left and right, RCA, and 1/4-inch, plus six 1/4-inch TRS Direct Inputs, with LED clip indication. Balanced XLR inputs connect cleanly to a console's balanced outputs and reject noise on the run to the rack, while RCA and 1/4-inch options cover consumer and pro sources. The clip LED lets an engineer set the input level just below overload for the cleanest possible cue feeds. A 10k ohm input impedance sits comfortably behind any source without loading it down. For a broadcast or tracking rack that connects to a full console, that professional input set makes the RA62c drop in without adapters or compromises.

Clean, Wide-Bandwidth Performance

The RA62c specifies a DC to 30 kHz frequency response, 90 dB signal-to-noise, distortion under 0.008 percent, and a 25 volt-per-microsecond slew rate. The exceptionally wide bandwidth and very low distortion mean the amplifier reproduces cue mixes cleanly, so performers hear an accurate version of the console feed. A 90 dB signal-to-noise ratio keeps the channels quiet between takes, and minus-65 dB crosstalk keeps one channel's Direct Input from bleeding into another. The fast slew rate preserves transients like the click and vocal consonants. For monitoring that has to be both loud and faithful, those specifications back up the RA62c's high-current output with real audio quality.

Built for Studio, In-Ear, and Broadcast Racks

The RA62c is made for studio cue monitoring, in-ear monitor stations, and broadcast or post-production racks where multiple listeners need individual, powerful feeds. A tracking studio uses it to give each musician a loud personal mix with their own Direct Input blend, while a broadcast facility feeds several monitoring positions from one source. Its 1U, 7-pound chassis mounts in any rack and runs from the included 12 VAC supply. Because it combines high output power with per-channel personal mixing, it does the work of a headphone amp and a small cue system together. For professional monitoring that has to be loud, clean, and personal, the RA62c is purpose-built.
