What is the Phantom Power?


Why do you need Phantom Power on your equalizers?
Phantom power is designed for an external power supply through the mic cable to the microphone that produces a signal that can be considerably lower in level hence the need for an external pre amplifier. A professional mic outputs its signal via three-pin XLR connector. Simply, the phantom signal is, +48 V DC is piggybacked on top of both AC signals on pin-2 and pin-3 via two resistors, without disturbance. The negative or "return path" to the DC supply is connected to pin-1. A female XLR as mic input and a male XLR to feed the mic signal to the preamp with a suitable 48 V DC power supply to make the positive and negative connections. Applying phantom powered units don't required the presence of the internal battery and can be supplied by stable external phantom power. Most of recently manufactured acoustic amplifiers or mixers provide phantom power. Even if your amplifier do not supply the phantom power, the phantom power adapter will be available in your nearest gear shop.

Common features of HT Blender Series


MASTER VOLUME controls to adjust the amount of loudness of the post equalized sound from Piezo and Magnetic pickup.
PHASE REVERSE SWITCH is a push/pull anti feedback switch. It reverses the phase 180 degree instantly that cancel the feedback some extent. Phase reverse switch will help you feel free from the feedback while you are playing with other sound systems.
PHANTOM POWER LED indicates when 48 V phantom power is applied to the unit.
LOW BATTERY LED is an indicator that check the 9 V battery power automatically without operating a battery check switch. It will stay on constantly when the battery power is lower than 4.0 V alerting that the 9 V battery has to be replaced with new battery.

Player's Tip  
  --  ABOUT MICROPHONE CONTROL OF HT-MC & HT-TBL
   Have you been 'Mic-Blending'?
The Microphone installed in EQ makes a natural effect to pick-up sound in a way to mix with it in suitable level.  
And the Microphone level and Sharpness can control volume independently even though Volume Control indicates “0” because it works separately with the Volume Control.
The Microphone makes an excellent effect when it is small concert or record.  But, in case of connecting with big output amplifier, it has to be turned down volume to avoid feedback.
At the recording using only Piezo Pick-up, the sound is likely to be dry and simple , Adding Microphone sound is the solution to create more natural and rich sound, also, even using only Microphone itself without Piezo, you can achieve good recording. But in this case, you have to notice that the sound can be changed as its position or angle.
You can make a good effect in case of being done properly in a small space or not close from loud speaker but, when the guitar amp or monitor speaker look toward guitar player, you’d better don’t use the Microphone.

 

 

 

HT-4
