SPA4-100
Power Amplifier
Caractéristiques
- Jusqu'à 200 watts par canal sous 4 et 8 ohms - Les sorties du modèle SPA4-100 sont conçues pour fournir jusqu’à 100 watts par canal dans des charges à basse impédance.
- Energy efficient — The SPA4-100 power amplifier employs an efficient class-D design to conserve energy and requires no active cooling, reducing operational costs.
- Sorties bridgeables pour une puissance plus élevée — Bridger les sorties du modèle SPA4-100 fournira jusqu'à 175 watts par paire de canaux sous ligne 70 V ou 100 V en mode bridgé.
- Auto-Ramp provides quiet startup and power-down — The Auto-Ramp circuitry ensures quiet and fast power up from Standby and seamless power-down following 28 minutes of inactivity, dramatically reducing power consumption.
- Unité montable en rack 1U, boîtier d’une largeur d’un demi-rack — Les amplificateurs SPA peuvent être montés en rack, dans 1/2 rack et leurs supports de raccordement intelligents permettent un montage facile sous la table et au mur.
