Can you bridge any stereo amplifier?

All stereo amplifier channel pairs on Director and Architect amps are capable of being bridged. IMPORTANT NOTE: When bridging channels, do not use a speaker rated at less than 8 ohms. When bridging amplifier channels each channel of the bridged pair “sees” one half of the speaker load.

What is bridge mode on AMP?

To operate an amp in bridged mode, a single input signal enters the amplifier and is split into two identical signals. One has its polarity inverted. The original signal is sent to one channel of the amp and the inverted signal is sent to the other channel.

Are all 2 channel amps bridgeable?

A two channel amp can be bridged to one channel, and a four channel amp into two channels. Bridging the channels increases the power output. An amplifier is usually bridged to combine two channels to power one subwoofer, or to combine four channels into powering two subwoofers.

Can you bridge a 4 channel amp to 1 channel?

He wanted to bridge 4 channel amp into 1 channel. It is not possible. 4 will become 2, and 2 channel can become 1.

What is the tda7294?

TDA7294 is an integrated, monolithic, Class AB audio amplifier designed specifically for Hi-Fi applications. The IC has a DMOS output stage and can deliver 100W RMS into an 8Ohm speaker at +/-38V dual supply. The TDA7294 has low noise, low distortion, good ripple rejection and can be operated from a wide range of supply voltages.

What are the power supply rails for the tda7293?

Supply rails are +/- 60V DC max for the TDA7293 and +/-50V DC for the TDA7294, transformer supply rails AC 32V- 0-32V to 35V-0-35V, recommendation is 32V-0-32V for 8 ohm operation.

What is the difference between VM and VSTBY in tda7294?

VM = 1.5V is the mute ON threshold and VM=3.5V is the mute OFF threshold. VSTBY = 1.5V is the standby on threshold and VSTBY = 3.5V is the standby OFF threshold. Typical input resistance of TDA7294 is 100KiloOhm.
