ZENITEL P-1670-Basic Power Amplifier 1 x 400W, 48VDC

The Phontech 1670 is a high performance, high efficiency 400 watt power amplifier designed to meet the needs of the most demanding PA/GA applications. The amplifier is designed to operate from a 48VDC power supply. It is only 1HU* high, weighs only 6.5kg and power consumption is only 480W at rated power output. Quiescent power consumption is also very low, at less than 5W.

Inputs and outputs

The Phontech 1670 features balanced line level inputs. The power amplifier provides one 100 volt line output.

Controls and metering

The front panel consists of a recessed power switch and recessed screwdriver adjustable controls for adjustment of the optional line surveillance board. The front panel of the Phontech 1670 includes a LED dB meter, Power status led, amplifier protection and line surveillance status leds.

Protection

The Phontech 1670 features a slow start function as well as overload and overdrive protection. Should the amplifier be overdriven, a current limiter will protect the unit, and in a worst case scenario the amplifier will shut down until the problem is resolved. Once the problem is fixed (shorted speaker line, or overdriven input), the amplifier will automatically reset and continue operation. The Phontech 1670 features internal heatzink with fan cooling. The fan will start to turn if the operating temperature exceeds 40°C, and turn at full speed at 50°C. The amplifier will protect itself at 90°C and resume operation when the temperature has dropped to 70°C. The fan exhaust is in the rear of the amplifier, and the air inlet is in the front.
