(1)OUTPUT LEVEL-LED-ANZEIGE

Diese LED-Anzeige dient der Anzeige des Ausgangspegels (–12 dB ... +12 dB).

(2)GAIN

Mit diesem speziell kalibrierten Regler mit Mittelrastung steuern Sie die Eingangsverstärkung der gesamten EQUALIZER-Sektion (3). Den Arbeitspegel von 0 dB (“Unity Gain”) stellen Sie sicher, in dem Sie die im Verlauf der Signalkette möglicherweise eingebüßte Verstärkung hier wieder aufholen. Grundsätzlich kann jeder Entzerrvorgang einen wahrnehmbaren Signalverlust bewirken. Um dies zu kompensieren, nutzen Sie den BYPASS-Schalter (5) und vergleichen zunächst den Pegel des nicht entzerrten Signals mit dem des entzerrten. Erhöhen Sie den GAIN-Wert anschließend so lange, bis der Pegel des entzerrten Signals in etwa dem des nicht entzerrten (Bypass-) Signals entspricht. Vertrauen Sie dabei Ihrem Gehör!

(3)EQUALIZER

Mit den kalibrierten, in der Mittelposition zusätzlich gerasteten Reglern der Equalizer-Sektion bestimmen Sie das Maß der Absenkung bzw. Anhebung im jeweiligen Frequenzbereich, wobei die maximale Absenkung 18 dB und die maximale Anhebung 12 dB beträgt (215B mit 15 dB Absenkung bis 15 dB Anhebung). Bei allen mit FLS ausgestatteten Geräten lassen sich eventuelle Kopplungsfrequenzen auf einen Blick anhand der oberhalb des jeweiligen Frequenzbands befindlichen LED lokalisieren.

(4)LOW CUT-FILTER

Mit diesem Schalter aktivieren Sie das Low-Cut-Filter (Hochpassfilter), das alle Frequenzen unterhalb der 40-Hz-Grenze abtrennt. Der Pegelabfall beträgt bei aktiviertem Low-Cut-Filter 18 dB pro Oktave. Diese Filterfunktion ist auch bei gedrücktem BYPASS-Schalter (5) aktiv, was durch die zugehörige, rote LED angezeigt wird.

(5)BYPASS

Bei gedrücktem Bypass-Schalter durchläuft das Signal den Equalizer unbearbeitet; einzige Ausnahme bildet das LOW-CUT-FILTER (4). Das Signal wird also vom Eingang (INPUT, 10 und 11) über das Low-Cut-Filter direkt an den Ausgang (OUTPUT, 8 und 9) überführt.

(6)POWER

Mit diesem Zweifach-Wippschalter schalten Sie das Gerät ein (Position “On”), wobei die Betriebsbereitschaft durch die grüne Power-LED angezeigt wird.

Q215B, QF131, QF215 specifications

Peavey, a renowned name in the audio equipment industry, has consistently provided high-quality professional audio gear. Among its product offerings, the Peavey QF131, QF215, and Q215B stand out as versatile equalizers that cater to the needs of audio engineers and musicians alike. These units are designed to enhance sound quality and provide precise audio control.

The Peavey QF131 is a dual-channel 31-band graphic equalizer known for its robust construction and reliability. It provides users with 31 frequency bands per channel, allowing for detailed and precise adjustments in various environments. One notable feature of the QF131 is its low-noise operation, which ensures that audio signals remain clean and free from unwanted interference. It also includes a bypass switch for seamless transitions between processed and unprocessed signals, making it a favorite among live sound engineers.

The QF215, on the other hand, is a dual-channel 15-band graphic equalizer, which is ideal for those who require a more streamlined equalization process. This model features a simplified interface that remains powerful enough for professional applications. It provides adjustable gain control, which allows users to boost or cut frequencies based on their specific sound needs. The QF215’s low-cut filter and high-pass filter options further enhance its flexibility, making it suitable for various audio applications, from live performances to studio recordings.

Complementing these models, the Q215B offers similar features with the added advantage of Peavey’s patented Switchable 20 Hz low-cut filter. This innovative technology is particularly useful for eliminating sub-bass frequencies that can muddy mixes. The Q215B also boasts excellent headroom, making it suitable for high-output scenarios without distorting the audio signal.

All three models share Peavey's commitment to high-quality audio processing. They incorporate durable controls and switchable input/output configurations, ensuring seamless integration into existing audio setups. With rugged metal housing, these equalizers are built to withstand the rigors of touring and frequent use, further enhancing their appeal for professional and semi-professional users.

In summary, the Peavey QF131, QF215, and Q215B are exemplary graphic equalizers that meet the rigorous demands of modern audio applications. Their extensive features, coupled with Peavey’s reliable technology, make them ideal choices for anyone seeking to enhance their sound system's performance and clarity.
