Powerful audio generator providing all kinds of analog test signals required for calibration, maintenance and repair of professional audio equipment

■Audio Generator

The Minirator MR2 is a powerful audio generator that provides all the analog test signals required for the calibration, maintenance, and repair of professional audio equipment.

Direct function keys surrounding the rotary wheel allow for fast, intuitive operation while providing precise adjustments. Equipped with a backlit LCD, illuminated mute button, safety hand strap, external DC power jack, and a USB interface for firmware updates, it offers enhanced operability.

■Features

Generator Functions
- Sine wave form, arbitrarily selectable frequency, up to +8
- Sweep signal, frequency intervals up to 1/12 octave
- White noise, pink noise
- Polarity test signal
- Delay test signal

Intuitive Operation
- Frequently changed parameters such as waveform, level, and frequency are easily accessed via the function keys. The rotary wheel sensitivity can also be adjusted with the ""sens"" key.

Mute Key
- The ""mute"" key mutes the generator output. The backlight flashes to indicate that the key is muted.

DC & USB Connector for External Power Supply
