Introduction

HEADLITE 3 

is a four input, four output headphone amplifier, with a six position self 

cleaning monitor select switch for each amplifier. It is designed to be as flexible as 

possible without introducing needless complexities. Its THAT Ingenius balanced 
input ensures very low distortion, transformer like rejection of interference, and very 
good frequency response. The inputs are on three pole jack sockets, and will also 
accept unbalanced signals on 2 pole jacks.

Its outputs are capable of driving virtually all headphones; we know of none it has 
problems with. The outputs are also designed to drive down long lines to cubicles 
with little or no loss of quality. The unit is compatible with -10dBV and +4dBu inputs 
(see page 5  - “2 & 5 Inputs”).

For users who require each output to feed multiple headphones, we offer the Power 
modification, which significantly increases the power output. The Power modification 
is fitted to Output 1 as standard but can be fitted to two, three or all four channels of 

HEADLITE 3

. It is a transistor amplifier with built-in limiting (soft clip) to help protect 

low impedance headphones from burn out. It will allow a number of high impedance 
headphones to be powered from the same output without a loss of signal level at the 
headphones; 

Additional power modifications can be retrofitted any time after purchase. Please 
speak to your retailer or direct to us for details.

® 

we’ve used up to 6 pairs of 400 Ohm headphones on one output and 

experienced no level drop.
