assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.
Features Specifications - measure: » peak power (fig.1) » RMS power (fig.2) » mean dB (fig.3) » peak dB (fig.4) » linear audio spectrum (fig.5) » 1/3 octave audio spectrum (fig.6) - auto or manual range selection - peak-hold function - speaker impedance selection - language selection - white backlit LCD - easy panel mounting - power measurement into 2, 4 or 8 ohms + bridged amp option - range: 300mW to 1200W @ 2 ohms - sensitivity: -34dBu (15.5 mVrms) - max.
I. CONSTRUCTION The audio analyzer consist of three parts: the basic module, the display module and the front panel. If required you can mount this kit into a housing, panel, ...

Overheating will damage the LCD screen.
Assembly II. ASSEMBLY 1. Roughen the 4 bolts with a knife, a file or some abrasive paper so it will be easier to solder them to the front panel. 2. Assemble the unit but do not yet tighten the bolts (fig.1). 3. Position the unit onto the rear of the front panel with the display is centred in the cut-away. Temporarily fix the unit to the rear using non-permanent tape (fig. 2 dering s.
Assembly 4. Solder 2 diagonal bolts to the front panel. Check if the display is still centred in the cut-away. Solder the remaining 2 bolts (fig. 3). 5. Now, fix the whole unit using the 4 nuts and remove the tape. - 12 - ��������������������������� �������������������� III.

Leds and how to use them Leds feature a specific voltage drop, depending on type and colour. Check the datasheet for exact voltage drop and rated current ! Never connect leds in parallel How to Calculate the series resistor: Example: operate a red led (1.7V) on a 9Vdc source. Required led current for full brightness: 5mA (this can be found in the datasheet of the led) Supply voltage (V) - led voltage (V) required current (A) 9V - 1.7V 0.
