AeroFrame Chassis — XSCACE technology
01 · AeroFrame Chassis™

The chassis is the heatsink.

6061-T6 aerospace aluminium machined to heatsink geometry, so the chassis itself works as the heatsink for the output stage, with a fan moving air across it. Every fastener is hidden.

PsySculpt — XSCACE technology
02 · PsySculpt™

Loudness that follows the volume.

ISO 226 equal-loudness compensation scaled to programme level, with harmonic synthesis that extends the perceived low end about an octave. It is not room correction.

SigmaDSP · ADAU1701 · PsySculpt™

Inside the Xylem

Every parameter is executed in real time by a dedicated DSP chip and shaped by XSCACE proprietary psychoacoustic processing. No approximations. No look-up tables.

ADAU1701

28/56-bit audio processor running at 50 MIPS. Executes all crossover calculations, parametric EQ biquad filters, and per-channel delay compensation in the digital domain — with onboard program storage that survives any power event.

XSCACE PROPRIETARY
PsySculpt™
EQUAL-LOUDNESS COMPENSATION

Equal-loudness compensation, running continuously. A log-decay peak detector tracks programme level with a 10 ms hold, and that measurement drives low and high shelving filters in real time — so the tonal balance you tuned at reference still holds at two in the morning. A level-tracked bass stage compresses rather than clips as the system is pushed, and a hard ceiling sits ahead of the converters. One switch bypasses the whole chain.

It is not room correction. Room correction is measured and applied in XSCACE Studio, from a microphone in the room. PsySculpt is about how the ear’s sensitivity changes with level — the Fletcher–Munson problem — and it runs whether or not anyone has measured anything.

Full correction — both ends lifted
Why the ends move

Hearing is not flat, and it does not stay the same shape as level changes. Turn a system down and the bass and the air leave the recording before the midrange does — which is why a mix that sounded right at reference sounds thin at midnight.

The level detector measures the programme continuously and the shelves apply the correction the ear needs at that level — corners at 60 Hz and 6.8 kHz, as implemented, with the midrange left alone. Nothing is added that was not in the recording. The balance is held where the ear stops holding it.

From the seat, not the rack.

Sit where the room will be listened to, open Studio on a Mac, iPhone or iPad, and the Xylem 3 appears on the network. Every crossover, delay, EQ band and limiter is edited there, live, with the music running — you hear the change from the chair it was made for, not from behind the amplifier. Calibrate by hand with the eleven-instrument toolkit, or let X-Sense EQ measure the room and write the correction for you.

Microphone at the seat, one or three positions, a room profile, Start. X-Sense sweeps the room, fits corrective EQ to the profile and writes it to the Xylem 3 live — then measures again and overlays before, target and after, so the correction is proven rather than promised. It tunes the Xylem and the Root 4 the same way.

  1. 1

    Speaker terminals

    Gold-plated binding posts for the speaker outputs. Signal comes in at line level on RCA — there is no speaker-level input.

  2. 2

    Line in and out

    RCA line input from any source or processor, and a line output to pass the signal on to another amplifier or a subwoofer.

  3. 3

    5 V out

    USB-C 5 V supply for a small accessory beside the amplifier, so a streamer or receiver needs no wall adaptor of its own.

  4. 4

    LAN

    Network control. XSCACE Studio finds the amplifier on the LAN with no configuration and tunes every parameter live over this port.

  5. 5

    AC

    IEC mains inlet. Standard detachable cord, supplied in the box.

  6. 6

    Power

    Illuminated push button. Settings live in non-volatile memory, so the amplifier returns to its last state after a power loss.

Control

Set up in XSCACE Studio

DSP control, intelligent room correction and a full professional calibration suite. Every parameter on this 3-channel dsp amplifier · class d · champagne — levels, delay, crossovers, limiter and EQ — opens in the same application that configures the rest of the range, so an installer learns one tool.

  • Live DSP Control

    Connect to any Xylem on the network and the full signal chain opens up: per-channel gain and delay, four crossover modes with live curve rendering, and six bands of parametric EQ per channel. Changes hit the DSP instantly over the local network — no round trips, no cloud. Discovery is zero-configuration: amplifiers announce themselves, so there is nothing to pair and no address to type. The delay block itself is accurate to 3 µs on a commanded 5.000 ms.

  • A Preset for Every XSCACE Speaker — and Yours

    Connect a Cane, a Bonsai, a QuadCane, and the amplifier lists an XSCACE factory preset for that speaker: crossover, EQ and limiter threshold already set from the model's real driver and power handling. Load it and the zone is playing correctly before anything has been measured. Tune further from there, then save the result under your own name — the next identical zone in the project starts from a proven configuration instead of the factory default.

  • One Number, Not Thirty-Four

    Per-channel limiting built on a peak-and-RMS combo: a 34-point gain transfer curve plus five time constants. You set one value — threshold in dBFS — because that is the number printed on the driver's datasheet and therefore the one an installer actually has. The device generates the curve from it, and the app states the consequence in plain language: at −6 dBFS, output is held there and peaks above it are caught in about 2 ms. Peak and RMS detectors run in parallel and whichever asks for more reduction wins. 33 factory presets across the range ship with thresholds derived from each speaker model's real power handling; an amplifier lists the presets matching its own channel count.

  • PsySculpt Low Extension

    A per-input side-chain that synthesises harmonics of fundamentals the cabinet cannot physically reproduce, so the ear infers a fundamental that is not being played — the usable low end reads about an octave below the driver's rated limit. A Cane rated to 150 Hz reads to about 75 Hz; a Bonsai rated to 300 Hz to about 150 Hz. It is not a bass boost — nothing below the driver's range is amplified, because there is nothing there to amplify. The control reads "extend down to X Hz" because it sets how deep the effect reaches rather than naming a filter, with an extension target down to 40 Hz and settings that ride along with system presets.

XSCACE Studio — Dashboard Overview
Dashboard Overview
What is the XSCACE Xylem 3?

2×100W plus 1×200W. Perfect for 2.1 setups with a dedicated bass channel. Network-configured DSP as standard, 218mm champagne chassis. Specified for 2.1 stereo and LCR cinema configurations in luxury residential home cinema rooms and high-performance audio installations across Canada, the UK, and India.

What is the power output of the Xylem 3?

The Xylem 3 delivers 2 × 100W + 1 × 200W into 8Ω (400W total), so a 2.1 system gets a dedicated 200W bass channel. It drives 4–8Ω loads.

What type of product is the Xylem 3?

The Xylem 3 is an amplifier product.

What DSP does the Xylem 3 use?

48 kHz, 28/56-bit fixed-point DSP (Analog Devices ADAU1701). Every crossover, EQ band, delay and limiter runs on that processor and is set from XSCACE Studio over the network; the configuration is stored on the Xylem 3 itself.

What does PsySculpt do on the Xylem 3?

PsySculpt is equal-loudness compensation running continuously on the DSP. A log-decay peak detector tracks programme level and drives low and high shelving filters from it, so perceived tonal balance stays constant as volume changes, with a level-tracked bass stage and a hard ceiling before the converters. Its harmonic bass extension also lets the low end read about an octave below the speaker's limit. It is not room correction — room correction is measured and applied in XSCACE Studio.

Can a room calibrated on the Xylem 3 be verified against CEDIA RP22?

Yes. XSCACE Studio includes a CEDIA RP32 verification checklist. CEDIA/CTA-RP22 defines four objective performance levels a room can be designed to, and CEDIA RP-32 is the companion practice for measuring and verifying whether it reached one. Set the target RP22 level and the room volume, and each parameter is marked pass or fail against RP22's table for that level — interchannel level and time, polarity, sub integration, background noise floor as an NCB rating, in-room bass extension, response below the transition frequency, early reflections against the direct sound, and reflection decay time to ISO 3382-1. Parameters needing a test the current version does not run are marked "not measured" rather than assumed, and the exported client report states that this is measurement to RP32 practice rather than a certification.

Do the Xylem 3 settings survive a power cut?

Yes. Gain, EQ, crossover, delay and limiter settings are held in non-volatile memory on the amplifier, so it returns to the configured state after any power event or firmware update.

What is the power output of the Xylem 3 at 4 ohms?

XSCACE publishes the Xylem 3's power rating at 8Ω only: 1 × 200W + 2 × 100W @ 8Ω — 400W total, ideal for 2.1 setups. It drives 4–8Ω loads, but no separate 4Ω power figure is published.

How much space does the Xylem 3 need?

The chassis is 64 mm high, 218.1 mm wide and 193.1 mm deep. Chassis depth is 193.1 mm. Allow 214.1 mm total clearance behind the front face — the rear speaker connectors add 21 mm once terminated.

How deep is the Xylem 3?

The Xylem 3 requires 193.1mm of depth.
