Subharmonic Synth

The Subharmonic Synth feature takes the low frequencies and “synthesizes” or creates new frequencies that are one octave lower. The two signals are then summed together. Also new, are two user adjustable parametric EQ ﬁlters and crossover frequency ﬁlter. These can be used to “shape” the sound and enhance the desired effect.

Equalization

The XTi2 Series provides two blocks of equalization in the signal processing. The input EQ block is before the crossover and is usually used for the room EQ. The output EQ block is after the crossover and is usually used for speaking tuning.

Input EQ: This input EQ block provides 6 ﬁlters per channel each with frequency, gain, and Q that is user controllable. This block also has a High and Low Shelf Filter per channel which has gain and frequency control.

Output EQ: This output EQ block provides 8 ﬁlters per channel each with frequency, gain, and Q control that is user controllable.

Crossover:

The crossover section provides users with the ability to enable a HighPass and LowPass ﬁlter per channel along with BandPass gain and the ability to change the polarity. This allows the Crossover section to be customized to most system conﬁgurations.

For the HighPass and LowPass Filters, you have the choice of the following ﬁlters: Butterworth 6dB/oct, Butterworth 12dB/oct, Butterworth 18dB/oct, Butterworth 24dB/oct, Butterworth 48dB/oct, Linkwitz-Riley 24dB/oct, and Linkwitz-Riley 48dB/oct.

The BandPass gain provides you with -15dB to +15dB of gain.

Delay

There is up to 50msec of delay available in the signal processing for time aligning your speakers. The software allows you to enter the amount of delay needed in the form of seconds, feet, or meters and does the calculation for you.

Operation Manual

PeakX Plus Limiter:

Feed-forward output limiter with user-adjustable attack, release and threshold (0.1 dB resolution), plus integrated feedback limiter to minimize ampliﬁer clipping.

Integrated Processing Features

Advanced Thermal Control

In this section, you can tailor the fan speed to speciﬁc applications. You have the choice of the following modes:

t /PSNBM

t &BSMZ

t 'VMM4QFFE

The fan mode can be changed using the front panel buttons at start-up or in the software. The default mode is normal and should work ﬁne for most applications. Early mode turns the fan on sooner at a “lower” temperature, and Full-speed mode turns the fan on full-speed full-time. Full-speed mode is not recommended for “dirty” environments.

Advanced Monitoring

This feature allows you to have software visibility of both the Power Supply Temperature and AC Line voltage. AC Line voltage is “derived” from the ampliﬁer rail voltage and is an approximation of the AC line voltage. This allows you to monitor the health of your ampliﬁers and provides for troubleshooting.

Front Panel Lock-Out

To disable or lock the buttons from the front panel, hold the Prev and Next at the same time until the screen says “locked”. The rotary knobs (attenuators) will still operate. To unlock, hold Prev and Next until the screen says “unlocked”.

The front panel can also be locked out from the software as well from the main panel. However once it is locked in the software, it can only be unlocked from the software. You cannot unlock from the front panel. The rotary knobs

(attenuators) will still operate.

Inbetriebnahme

Stereo DSP AUS

Dies ist die Standardwerkseinstellung des Verstärkers. Der Verstärker ist für den Stereomodus konﬁguriert, wobei sämtliche Verarbeitungsfunktionen deaktiviert sind.

1. Schließen Sie die rechte/linke Signalquelle mit Hilfe der XLR-Stecker an Kanal 1 und Kanal 2 an

2. Schließen Sie mit Hilfe von Speakon blankem Draht einen Lautsprecher an jeden Kanalausgang an

ACHTUNG: Vor Inbetriebnahme Ihres Verstärkers lesen und befolgen Sie bitte die wichtigen Sicherheitsanweisungen, die Sie zu Beginn dieser Bedienungsanleitung ﬁnden.

Werksvoreinstellung Nr. 2: BRÜCKE

Wenn der Verstärker in den BRÜCKEN-Modus (Brücke-Mono) versetzt wird, wird die Leistung beider Verstärkerkanäle als einzelne 8 oder 4 OhmLast bereitgestellt. Die Verstärker der Serie XTi2 sind werkseitig mit einer Voreinstellung versehen, die die Konﬁguration des Verstärkers für diesen Betrieb erleichtert.

Bevor Sie beginnen, stellen Sie sicher, dass Sie:

die Signalquelle mit Hilfe von XLR-Steckern an Kanal 1 und Kanal 2

1. angeschlossen haben (die Verstärkereingänge werden automatisch summiert, wenn diese Voreinstellung gewählt wird),

den Lautsprecher wie gezeigt angeschlossen haben.
