Leggendaria testata per basso Peavey 400 versione 220 volt. Questo è il modello MK3 prodotto nel 1978.

A differenza di molte testate analoghe sul mercato questa è stata revisionata con la sostituzione dei principali condensatori elettrolitici tutti top di gamma (come TAD, F+T, ecc...).

E' un amplificatore subito pronto per suonare senza nessun intervento da fare.

Molto ricercato per generi come Stoner, Doom, Sludge, ecc...

PEAVEY BASS MARK III - MODELLO 400B (1978)

* Produttore: Peavey Electronics (Meridian, Mississippi - USA)

* Anno di produzione: 1978

* Tecnologia: Stato Solido (Solid State)

* Modulo Finale di Potenza: Peavey 400B

SPECIFICHE DI POTENZA

* Potenza su 2 Ohm: 300 Watt RMS (a 1% T.H.D.)

* Potenza su 4 Ohm: 210 Watt RMS (a 1% T.H.D.)

* Impedenza minima tollerata: 2 Ohm

SISTEMI DI PROTEZIONE E CONTROLLO DINAMICO

* DDT™ Compression: Circuito di compressione proprietario (Distortion Detection Technique) con indicatore LED sul pannello frontale. Evita il clipping del finale e protegge i coni dei diffusori.

* Protezione termica: Sensore automatico contro il surriscaldamento.

SEZIONE PREAMPLIFICAZIONE E CONFIGURAZIONE CANALI

* Architettura: 2 Canali indipendenti miscelabili (Channel A e Channel B) gestiti da circuito logico Automix.

* Canale A (Equalizzazione Attiva):

* Controlli di guadagno: Pre Gain (con switch Pull-Bright), Post Gain.

* Equalizzazione: Low (attivo), High (attivo), più sezione Parametric Mid con controlli rotativi Shift (frequenza) e Function (taglio/esaltazione).

* Canale B (Equalizzazione Passiva):

* Controlli di guadagno: Pre Gain (con switch Pull-Bright), Post Gain.

* Equalizzazione: Bass, Middle, Treble (circuito passivo classico).

* Master Equalizer:

* Equalizzatore grafico attivo a 6 bande.

* Interruttori selettori dedicati per assegnare o escludere l'EQ grafico in modo indipendente sul Canale A e/o sul Canale B.

CONNESSIONI PANNELLO FRONTALE (Automix System)

* Input 1 (High Gain): Ingresso standard ad alta sensibilità per bassi passivi (+6 dB).

* Input 2 (Low Gain): Ingresso attenuato per bassi attivi o con elettronica ad alto segnale d'uscita.

* Input Automix: Attiva entrambi i canali contemporaneamente, permettendo di combinare e miscelare le due diverse tipologie di equalizzazione (A + B).

CONNESSIONI PANNELLO POSTERIORE

* Speaker Outputs: 2 uscite Jack da 1/4" collegate in parallelo per diffusori acustici.

* Patching & Line Signals:

* Preamp Out (Uscita preamplificatore, 1V RMS)

* Power Amp In (Ingresso directo al finale di potenza)

* Line Out (Uscita di linea bilanciata e compensata in frequenza)

* Bi-Amp Crossover: Crossover elettronico integrato con uscite dedicate Bi-Amp High Out e Bi-Amp Low Out per configurazioni multi-amplificate.

* Footswitch Port: Presa DIN per il collegamento del pedale remoto originale (selezione Canale A, Canale B o combinazione Automix).

Legendary Peavey 400 bass head (220V version). This is the MK3 model, manufactured in 1978.

Unlike many similar heads on the market, this unit has been serviced and features newly installed, top-tier electrolytic capacitors (such as TAD, F+T, etc.).

It is ready to play immediately, with no further work required.

Highly sought-after for genres such as Stoner, Doom, Sludge, etc.

PEAVEY BASS MARK III - MODEL 400B (1978)

* Manufacturer: Peavey Electronics (Meridian, Mississippi - USA)

* Year of production: 1978

* Technology: Solid State

* Power Amp Module: Peavey 400B

POWER SPECIFICATIONS

* Power at 2 Ohms: 300 Watts RMS (at 1% T.H.D.)

* Power at 4 Ohms: 210 Watts RMS (at 1% T.H.D.)

* Minimum load impedance: 2 Ohms

PROTECTION AND DYNAMIC CONTROL SYSTEMS

* DDT™ Compression: Proprietary compression circuit (Distortion Detection Technique) with front-panel LED indicator. Prevents power amp clipping and protects speaker cones.

* Thermal protection: Automatic overheat sensor.

PREAMP SECTION AND CHANNEL CONFIGURATION

* Architecture: 2 blendable independent channels (Channel A and Channel B) managed by an Automix logic circuit.

* Channel A (Active Equalization):

* Gain controls: Pre Gain (with Pull-Bright switch), Post Gain.

* Equalization: Low (active), High (active), plus Parametric Mid section with rotary controls for Shift (frequency) and Function (cut/boost).

* Channel B (Passive Equalization):

* Gain controls: Pre Gain (with Pull-Bright switch), Post Gain.

* Equalization: Bass, Middle, Treble (classic passive circuit).

* Master Equalizer:

* 6-band active graphic equalizer. * Dedicated selector switches to independently engage or bypass the graphic EQ on Channel A and/or Channel B.

FRONT PANEL CONNECTIONS (Automix System)

* Input 1 (High Gain): Standard high-sensitivity input for passive basses (+6 dB).

* Input 2 (Low Gain): Attenuated input for active basses or instruments with high-output electronics.

* Automix Input: Activates both channels simultaneously, allowing the two different equalization types (A + B) to be combined and blended.

REAR PANEL CONNECTIONS

* Speaker Outputs: Two parallel-wired 1/4" jack outputs for speaker cabinets.

* Patching & Line Signals:

* Preamp Out (1V RMS)

* Power Amp In (Direct input to the power amplifier stage)

* Line Out (Balanced, frequency-compensated line output)

* Bi-Amp Crossover: Integrated electronic crossover with dedicated Bi-Amp High Out and Bi-Amp Low Out outputs for multi-amplified setups.

* Footswitch Port: DIN socket for connecting the original remote footswitch (selects Channel A, Channel B, or Automix combination).
