ZAPCO Z-II SQ Competition Series - Z-150.4 II

The Zapco Z-150.4 II 4-channel amplifier is an amplifier for  Competition Sound Quality with  Class AB amplifier technology, it delivers a power of 4x 275 Watt RMS at 2 Ohm
integration of the  new amplifier of the Z-II SQ Competition Series
In recent years, Zapco has developed two special amplifier series that take car sound to a new level. The AP amplifier of the Z series, the ultimate SQ amplifier for high end - no controls except gain. Zapco has also  The Z-SP series amplifiers are designed for SQPL fanatics who play full-time at full volume  Want to listen to music but still want to maintain audiophile sound? With the Z-II SQ Competition Series, Zapco has revisited the roots of the Z series with which it all began and made numerous improvements. 

• A new TI operational amplifier that offers significantly better signal-to-noise ratio and lower noise floor.
• Use of the same audiophile capacitors found in the LX and SP amplifiers.
• The power supply has been upgraded with more capacity, less internal resistance and lower inductance for higher efficiency.
• A power supply with more MOSFETs to improve efficiency and current consumption.

• An improved power supply - Higher performance - New high-end audio caps like the SQ amps
• New low-noise TI operational amplifiers as in the SQ amplifiers - Improved Tiffany-style RCA connectors for panel mounting
• The end plates are now recessed like the LX amplifiers for a cleaner look
• The plastic controls have been replaced by the new metal potentiometers and switches. The new potentiometers also have grids (like the SP amplifiers), so that the crossovers and gains can be set identically with several amplifiers.  can.
