RODE
AND SCHWARTZ HAD A BOOTH VERY CLOSE TO OURS AT THE AES SHOW AND
ON THE LAST DAY WE WERE THERE THEY WERE KIND ENOUGH TO RUN SOME
FREQUENCY RESPONSE TESTS ON THE X73 AND THE NEVE 1073. THESE TESTS
WERE RUN WITHIN A TEN MINUTE PERIOD (BECAUSE WE HAD TO PACK UP)
AND SO LEVEL MATCHING AND SUCH ARE NOT PRECISE.THESE TESTS WERE
DONE QUITE INFORMALLY AND ARE PRESENTED AS SUCH. ALSO, SINCE WE
FINISHED THE PROTOTYPE THE NIGHT BEFORE THE SHOW, AND DID NOT
HAVE A COUPLE OF THE TERMINATION CAPS THAT ARE NORMALLY PUT ACROSS
THE SECONDARY OF THE INPUT TRANSFORMERS, THE UNITS MEASURED SLIGHTLY
DIFFERENTLY ON THE HIGH END. WE HAVE SINCE PUT IN THOSE CAPS AND
COMPARED THE UNITS AND FOUND THEIR RESPONSES TO BE MUCH CLOSER WITH THE TERMINATION CAPS ADDED.
THE
BELOW TEST IS WITH THE EQ ENGAGED ON BOTH UNITS AND SET AT 360HZ
WITH BOTH ALL THE WAY UP. THE VINTECH IS IN YELLOW AND THE NEVE
IS IN GREEN.
THE
FOLLOWING TEST IS WITH BOTH UNITS TURNED ALL THE WAY UP ON THE
LOW AND HIGH SHELVING. I'M NOT SURE WHAT FREQUENCY WE USED FOR
THE LOW SHELVING, BUT YOU CAN SEE AGAIN THAT THE CURVES ARE IDENTICAL.
THE VINTECH HIGHS ARE A LITTLE HOTTER .
THE
BELOW TEST IS WITH BOTH UNITS SET AT 4800HZ AND TURNED ALL THE
WAY UP. AGAIN VINTECH IS YELLOW AND NEVE IS GREEN.
THE
BELOW TEST IS WITH BOTH LOW FREQUENCY SHELVINGS SET AT 110HZ AND
TURNED ALL THE WAY UP.
THE
BELOW TEST IS WITH BOTH UNITS SET AT 1.6K AND TURNED ALL THE WAY
UP. EVEN THOUGH THE HIGH SHELVINGS ARE NOT MATCHED, ONE CAN SEE
THAT THE CURVES FOR 1.6K ARE THE SAME.
