Providence Provolt 9 PV-9 Multiple-output PSU

Multiple-output power supply with 6 x 9 Volts DC outputs and 100mA each, it actually delivers constant 9.6V approximately, equivalent to a new alkaline battery. This extra 0.6 Volt looks like a small difference but it's a noticeable change in sound quality. Unlike most multiple-output power supplies which connect their outputs in parallel, the Provolt 9 employs star grounding that effectively suppresses hum for clean, high-quality sound. Double Filtering on each output ensures exceptionally clean power supply, which is essential for a high resolution and refined sound. If any of the outputs is accidentally shorted, a short-protection feature protects the internal circuitry from damage while keeping all other outputs active. When the cause of the short is removed, the affected output will recover automatically and normal DC supply will resume. Included adapters: 3 x 30cm DC and 3 x 50cm DC.
