What does BTL mean on an amp?
bridge-tied load
By bridging the outputs from the two linear amplifiers within the TPA610xA2 device across the speaker load, it is possible to get an increase in output power without increasing the supply voltage. This configu- ration (shown in Figure 1) is called a bridge-tied load (BTL).
What is parallel BTL?
Parallel BTL function Use the parallel BTL function to drive the speakers for each channel via the 4 amps built into this unit and realize sound quality with damping force. Select “Parallel BTL” from “Speaker Configuration” – “Amplifier Mode” in the settings menu.
What is LM3886?
The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% THD+N from 20Hz–20kHz.
What is a Thiele network?
The Thiele Network Inductors have a low impedance to low frequency current and a high impedance to high frequency current. Audio signals are relatively low frequency, so they will flow through the inductor uninhibited.
What is BTL and Pbtl?
BTL is series amps. In this case, 4 amps wired as two BTL’s. PBTL is paralleled amps for same V but 2x the amps, hence it needs 2ohms to reach 100W.
What is BTL driver?
Glossary Term: BTL The ground-tied speaker can have a swing from zero to the amplifier’s supply voltage. A BTL-driven speaker can see twice this swing because the amplifier can drive either the + terminal of the speaker or the — terminal, effectively doubling the voltage swing.
What’s louder series or parallel?
As a general rule, parallel speakers are louder than series speakers. That’s because: Wiring speakers in series increases the total speaker impedance (Ohms) load, decreasing how much electrical current (amps) can flow. This means the amp or stereo’s power output will be lower.
What is Gainclone amplifier?
Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio. It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series. As an amplifier it is highly regarded by many in the DIY community.
What is LM386 IC?
The LM386 is an integrated circuit containing a low-voltage audio power amplifier. The IC consists of an 8-pin dual in-line package (DIP-8) and can output 0.25 to 1 watts of power, depending on the model, using a 9-volt power supply.
What is Pbtl amplifier?
PBTL is paralleled amps for same V but 2x the amps, hence it needs 2ohms to reach 100W.
What is a BTL amplifier circuit?
BTL amplifier circuit using components BJT (Bipolar Junction Transistor) which is identical / exactly the same as the amplifier. In the BTL amplifier circuit has two input signals (input) the V1 and V2. Under ideal conditions, when both inputs are identical (Vid = 0), then the output VOD = 0.
How to enlarge BTL amplifier circuit (Cascade)?
Reinforcement can be used to enlarge the two-level BTL amplifier circuit (cascade). BTL amplifier circuit output is connected to the input BTL amplifier circuit is the next level. With such a large total gain (Ad) is the product of the first BTL amplifier circuit gain (VD1) and the strengthening of the second differential amplifier (Vd2).
What is an emitter follower in BTL circuit?
To be able to produce an output voltage to earth (ground) is equal to the voltage between the two outputs (VOD), then one of the BTL amplifier circuit output of the second level is connecting with an emitter follower (emitter follower).
