The magnetic amplifier colloquially known as a "mag amp" is an electromagnetic device for amplifying electrical signals. The magnetic amplifier was invented early in the 20th century, and was used as an alternative to vacuum tube amplifiers where robustness and high current capacity were required. The magnetic amplifier was most prominent in power control and low-frequency signal applications from to about , when the transistor began to supplant it. Combinations of transistor and mag-amp techniques are still used. Visually a mag amp device may resemble a transformer , but the operating principle is quite different from a transformer — essentially the mag amp is a saturable reactor.

Enhanced system status monitoring functions such as Input and Load monitoring ensure suitability in an emergency situation. The DSP integrated within the 30D incorporates comprehensive loudspeaker management, switchable filtering functions as well as user definable equalization and delay capabilities.

The device itself contains LEDs to display power, input, data and mute status. The LoadMatch function integrated within the 30D amplifier electrically compensates for the properties of loudspeaker cable used. Input and output connectors are all Euroblock sockets. The digital input pairs contain independent Sample Rate Converters.

Each input features a separate input gain, meaning sources with various output levels can be used without requiring an external mixing device. All eight individual inputs can be used simultaneously, then summed and routed to any of the four outputs. The System check feature can verify the status of a complete reinforcement system by measuring the impedance of the connected loudspeakers. Each driver in the system is checked and compared to the default impedance values for each particular cabinet.

This calibration ensures that each loudspeaker performs within a tolerance band, and indicates possible damage to system components. The Input monitoring function can detect an incoming pilot signal regardless of whether this input is routed to an output. The Load monitoring function can detect a possible loudspeaker malfunction.

This feature automatically checks load impedance to calculate individual driver status and report any failure. The GPIO connector offers five pins providing additional digital control lines which can be configured to be either an input or output.

This enables the use of external devices to control and detect certain functionalities within the 10D and 30D amplifiers. The separate fault contact allows a general device error to be remotely indicated. The D20, D80, 10D and 30D amplifiers feature an integrated web interface to control individual amplifiers via a standard web browser. In small applications, this allows direct control of each device without the need to create an R1 Remote control software file.

D80 amplifier

A budget range of units with a wide range of applications in industrial, commercial and recreational installations. All units carry a 5 year parts guarantee. The amp has 6 inputs including 5x balanced mic dBu or line level dBu , and 1x twin phono RCA , dBu 2kohm input. A telephone system input paging output from phone system not BT line , 0dBu 10kohm. Vox priority override is on mic and telephone inputs.



The 2 RU four channel D80 amplifier is a high power density amplifier, ideally suited for use in both mobile and installation environments. The same applies to the two band equalizers, providing optional parametric, asymmetric, shelving or notch filtering. The D80 incorporates a colour TFT touchscreen, offering quick access to the menu structure, while the rotary encoder can be used for fine adjustment. The front panel and the integrated touchscreen of the D80 amplifier is tilted up for ease of operation when the amplifier is below eye level. The equal ratio of signal input to amplifier output channels increases the application flexibility particularly for monitor, frontfill or effect channel use. The LoadMatch function integrated within the D80 amplifier enables the electrical compensation of loudspeaker cable properties, without the need for an extra conductor. This results in an increased accuracy of audio reproduction over a bandwidth of up to 20 kHz, preserving the tonal balance when cable lengths of up to 70 m ft are used.
