Driver chassis

Find the best driver for your project
DETERMINE IDEAL PLAYBACK RANGE
DETERMINE PARAMETERS FOR VOLUME CALCULATION (VAS, QTS..)
DETERMINING THE IMPEDANCE CURVE Z FOR THE CROSSOVER NETWORK
MEASURE DISTORTION

Loudspeaker box

Identify tuning gaps: How do all the speakers play together?
HOW LOW DOES THE BASS GO?
IS THE BASS REFLEX CHANNEL TUNED CORRECTLY?
WHAT IS THE FREQUENCY RESPONSE OF THE ENTIRE BOX?
DOES THE ACUTE FREQUENCY RESPONSE FIT THE CALCULATION OF THE CROSSOVER?

MP3 or HiFi Network Player, Bluetooth Equipment

Test modern audio players which can not be sourced with audio signals via cable input.
External test signals (like MP3 files) are stored on the test device itself or transmitted NAS server. External measuring signals are available separately.

stute.x1A supports this measuring mode.

Audio crossover

Check crossover frequency or filter slope.
DOES THE MIDRANGE SPEAKER GET SIGNALS FROM 500HZ TO 5KHZ AS DESIRED?
DOES THE IMPEDANCE CORRECTION WORK?
DOES THE SLOPE 12DB/OCTAVE FIT TO THE SPECIFICATION?
DOES THE IMPEDANCE OF THE LOUDSPEAKER CHANGE THE BEHAVIOR OF THE CROSSOVER?

Component measurement

Check values of R, L, C

Amplifier

Test of hifi amplifiers and receivers.
HOW LINEAR IS THE FREQUENCY RESPONSE?
HOW HIGH ARE THE DISTORTIONS?
DO THE TONE CONTROLS OR LOUDNESS WORK?
ARE THE CHANNELS EQUALLY GAINED?WIE LINEAR IST DER FREQUENZGANG?
