SKEMA RANGKAIAN POWER BTL
Bagi anada yang suka otak atik elektronika,ingin power amplifier anda
yang setereo dibuat mono tanpa merubah rangkaian inti power
amplifier anda,berikut rangkaiannya:Audio amplifier beroperasi baik dalam konfigurasi ("normal") B

Setelah brosing kesana kemari akhirnya dapat rangkaian amplifier 1000
watt,tapi kalo mau dibuat agak rumit nih.....Skema Rangkaian Audio Distributor
rangkaian audio distributor adalah rangkaian yang mampu menditribusikan
sinyal audio stereo (2 kanal), menjadi 3 kanal stereo, untuk
distribusikan ke 3 buah power amplifier stereo secara full stereo, full
power, dan rangkaian ini mempunyai keistimewaan:- Menjaga bidang dinamika audionya tetap tinggi
- Dapat mempertahankan desah agar tetap rendah

Transmit Audio Setup
Introduction:
Setting Up Your Transmitter Audio 
This
page was designed to step you through the several different aspects of
setting up your
transmit audio from component ordering to individual
processor settings necessary in achieving that ultimate SSBaudio that
you have been
looking for. First, let me set the record straight; If you are looking for near AM broadcast quality audio on SSB, then this page was designed for you! If you are looki |
60 Watt Guitar Amplifier + Tone Control

The following is a circuit of amplifiers are equipped with the appropriate regulatory tone in use to strengthen the electric guitar, using a single-rail supply of about 60V and capacitor-coupling for the speaker . The advantages for a guitar amplifier are the very simple circuitry, even for comparatively high power outputs, and a certain built-in degree of loudspeaker protection, due to capacitor C8, preventing the voltage supply to be conveyed into loudspeakers in case of output transistors' failure.

In all cases where Darlington transistors
are used as the output devices it is essential that the sensing
transistor (Q2) should be in as close thermal contact with the output transistors as possible. Therefore a TO126-case transistor type was chosen for easy bolting on the heatsink, very close to the output pair
R30 must be trimmed in order to measure about half the voltage supply across the positive lead of C7 and ground. A better setting can be done using an oscilloscope, in order to obtain a symmetrical clipping of the output wave form at maximum output power
Note:
To set quiescent current, tide ampare meter in series between supplay with this series, then do the following

- Set the volume control to the minimum and Trimmer R3 to its minimum resistance.
- Power-on the circuit and adjust R3 to read a current drawing of about 30 to 35mA.
- Wait about 15 minutes, watch if the current is varying and readjust if necessary.

Rangkaian Pre-Amp Spul Gitar
This
is a pre-amp guitar circuit suitable for high impedance type electric
guitar pickups. The circuit is based on a uA 741 op-amp (IC1). The IC1
is wired as a non-inverting amplifier. Resistor Variable R1 can be used
as a volume controller. Resistor Variable R6 can be used as tone
controller. The switch S1 is used to produce “brilliant” or “soft” tonal
effects.
