An acceleration circuit is prepared with a straight line wave detector and a logarithm compression machine, and high-speed meter is driven so that it may catch and point to the momentary peak of a signal and can answer quickly.
Since speed of response is 100microsec, exact meter directions can be performed by incoming signal 1 10kHz wave.

Three steps, -20dB, 0dB, and +20dB, unite a voltage level, x1 and x10 unite two steps of power levels, and five steps of range changes are possible.

A wide scale type of -50dB - +5dB is adopted as meter. On voltage, it reaches far and wide from 300mW to 300W by a maximum of 17.7v (+20dB) and power from 300mV (-20dB), and a readout is possible.

The input has equipped three lines of two inputs for levels, and one input for speakers.
The input for levels connects a pre out, RECOUT, etc. with US pin terminal.
Since both lines are parallel connection, although the terminal by the side of amplifier is plugged up, connection with other apparatus can be performed.

By attaching optional carrying handle TO-1 (3,000yen), standard rack-mounted one of 480mm width is possible.
