Overview:
The Sceptre S6 Two-Way CoActual Studio Monitor with DSP
Temporal Equalization by PreSonus articulates nuances of your music that can't
be reproduced by conventional designs. The Sceptre S6 features a panoramic
soundstage and a wide dynamic range. The advanced coaxial design works
integrally with a 32-bit/96 kHz, dual-core processor running Fulcrum Acoustic's
TQ Temporal Equalization Technology.
- The Presonus Sceptre S6 features a 6.5" low/mid-frequency
driver, a 1" horn-loaded tweeter and front-firing acoustic ports. The
systems are biamplified, with each transducer powered by an independent 100W
RMS, Class D power amplifier with an internal heat sink. Sceptre has an internal
power supply and a blue power-indicator LED. The S6 studio monitor has a
balanced XLR and a 1/4" TRS line-level input with an A-taper level
control.
- Coaxial systems, such as the S6, have both drivers on the
same axis— providing a single point source for a consistent acoustic center.
This results in symmetry of response on both the horizontal and vertical axes,
at any given angle. The crossover transition is, therefore, seamless at all
angles.
Onboard TQ Temporal Equalization by Fulcrum Acoustics
- Each Sceptre monitor contains a 32-bit/96kHz, dual-core,
active floating-point DSP chip that powers Fulcrum Acoustic's TQ algorithms.
The TQ algorithms use fully addressable Finite Impulse Response (FIR) filters
to eliminate horn reflections and to correct linear time and amplitude
anomalies. Loudspeakers tuned with TQ provide a crisper stereo image, greater
soundstage depth, more separation between the elements of a complex mix,
increased resistance to feedback, more seamless transitions between distributed
loudspeakers, and a less fatiguing listening experience.
Acoustic Space Control
- The Acoustic Space Control is a second-order shelving filter
centered at 100Hz. It can remain flat or attenuate by 1.5dB, 3dB, or 6dB—
reducing the boundary bass boost that occurs when the monitor is placed near a
wall or corner.
Acoustic Tuning Controls
- The High-Frequency Driver Adjust switch can boost the
tweeter by 1dB, or cut by 1.5dB or 4dB. The High-Pass switch rolls off the lows
below a specified frequency, 60, 80, or 100Hz, at a slope of 12dB/octave. This
control is important if you are using a subwoofer in conjunction with the
Sceptre.
Input Sensitivity Control
- A sensitivity control ranging from +4dBu to -10dBV helps you
match the Sceptre to your mixer's outputs.
Thorough Protection Circuitry
- RF shielding protects against radio frequencies that could
be introduced to the signal and become audible. Sceptre monitors also provide
overheat protection, current-output limiting and subsonic protection.
"Soft startup" amplifiers prevent damaging pops from sounding through
the speakers when you power them up.
Features:

Inputs and outputs
- Balanced XLR and ¼-inch TRS line-level inputs with A-taper level control
Rear Panel Connections:
Input
- Line-level Inputs. The Sceptre S6 provides a choice of two balanced inputs: XLR and ¼” TRS. These inputs accept a line-level signal from your audio source and feed that signal to the monitor’s built-in power amplifiers. When both balanced connections are in use, the TRS input supersedes the XLR input.
- Input Level: Sets the amount of gain applied to the input signal. This is not a volume control in the traditional sense; instead, it sets the level of the input signal before it is amplified
Acoustic Tuning Controls
- Acoustic Space: Cuts the level of all frequencies below 250 Hz by the specified amount (-1.5, -3, or -6 dB) to compensate for the bass boost that occurs when the monitor is placed near a wall or corner. Can be defeated by setting it to Linear. Repeatedly pushing the corresponding button cycles through the available settings.
- HF Driver: Boosts or cuts all frequencies above 2 kHz by the specified amount (+1, -1.5, or -4 dB). Can be defeated by setting it to Linear. Repeatedly pushing the corresponding button cycles through the available settings.
- HP Filter: Rolls off the level of all frequencies below the specified frequency (60, 80, or 100 Hz), with a slope of -24 dB/octave. Can be defeated by setting it to Linear, in which case, the monitor’s natural roll off takes over (42 Hz for S6, 38 Hz for S8). Repeatedly pushing the corresponding button cycles through the available settings.
Power
- IEC Power Connection: Your Sceptre S6 accepts a standard IEC power cord
- Power Switch: This is the On/Off switch. The power status is indicated by an LED on the front of the cabinet
