HERITAGE AUDIO 73EQJR Equalizer - Format 500
The 73EQ JR is a complete line input module for the 500 Series.
Not only does it share the 3-band equalizer with its big brother, the Heritage Audio 73 80 Series, but it also shares the same transformer-coupled line preamp and a transformer-balanced Class A output stage.
These facts make the 73EQ JR unique in its class, being able to capture a full transformer-based, Class A sound without relying on external preamps.
The EQ features the same Baxandall-style high and low stages as the HA73 80 series, with the addition of a high frequency selector. 4 different frequencies are possible instead of the fixed 12Khz.
The midrange is exactly the same as the dual inductor, thick boosts in the lows and smooth in the highs without becoming muddled or leaky.
The line preamp has a range of +6 to -20dB, allowing for powerful eq boosts without overloading the A/D converters.
Finally, special care has been taken with power management, with the implementation of a slow-start +24v internal regulation (about 20 seconds to reach full voltage). This makes your 73EQ JR independent of the rest of the slots and makes your lunchbox PSU happier.
