Page 5: General Description
2. GENERAL DESCRIPTION TOA's FS-7006PA (600 W) and FS-7012PA (1,200 W) are power amplifiers designed for 100 V line and high impedance applications. By mounting an optional YA-7000 module in the power amplifier and connecting it to a standby amplifier, the power amplifier can be automatically switched over to the standby amplifier if the power amplifier fails, allowing broadcasts in progress to continue uninterrupted. -
Page 6: Installation Precautions
• Because the amplifier is heavy (24.8 kg for FS-7006PA, 35.4 kg for FS-7012PA), be sure to reinforce the fittings used to fix the amplifier in place when mounting in a rack and requiring extra strenght. -

• Standby amplifiers cannot be shared with other main amplifiers. • Only 1 piece of FS-7006PA or FS-7012PA can be connected to the YA-7000's main amplifier input and standby amplifier input. Never connect 2 or more amplifiers to each of these terminals, as the excessive load could cause the amplifier to fail. - Page 13 [Wiring Diagram] 100 V line Composite impedance 16.7Ω (FS-7006PA) Speaker Output Terminal 8.3Ω (FS-7012PA) Main Amplifier YA-7000 Input Terminal [Main Amplifier] Standby Amplifier Input Terminal Speaker Output Terminal Audio Signal Input Terminal [Standby Amplifier] Speaker Output Terminal Audio Signal Input Terminal...
