Overview
The Heritage Audio 73EQ Junior 500 Series EQ Module is a fully featured Line Input module for the 500 Series.
It not only shares the 3-band Equalizer with his big brother, the Heritage Audio 1073, but also shares the same transformer coupled line preamp and Class A transformer balanced output stage.
These facts make the 73EQ JR unique on its class, being able to capture a full transformer based, Class A sound without relying on external preamps.
The Equalizer features the same Baxandall type High and Low shelf found in the HA1073, with the addition of a high frequency selector switch. 4 different frequencies are possible instead of the fixed 12Khz one.
The mid band is the same exact dual inductor one, thick low and sweet high midrange boosts without becoming muddy or brittle.
The line preamp has a range of +6 to -20dB, allowing heavy eq boosts without overloading A/D converters.
Finally, special care has been taken with power handling, implementing internal +24v slow turn on regulation (about 20 seconds to reach full voltage). This makes your 73EQ JR independent of the rest of the slots and makes your lunchbox´s PSU happier.
