The Sceptre S8 Two-Way 8" CoActual Studio Monitor with
DSP Temporal Equalization by PreSonus articulates nuances of your music that
can't be reproduced by conventional designs. The Sceptre S8 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 Sceptre S8 features a 8" 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 S8 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 S8, 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.

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 S8 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
buttoncycles through the available
settings.
Power
IEC Power Connection: Your Sceptre S8 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
