DETERMINE IDEAL PLAYBACK RANGE
DETERMINE PARAMETERS FOR VOLUME CALCULATION (VAS, QTS..)
DETERMINING THE IMPEDANCE CURVE Z FOR THE CROSSOVER NETWORK
MEASURE DISTORTIONS

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?

Audio filter

Check crossover frequency or filter slope. In addition, x1A contains a measuring device for the components R-L-C.

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?

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?

MP3 Player, HiFi Network Player, Bluetooth Equipment

This mode is for modern audio players which can not be sourced with audio signals via cable input. Or to test the wireless audio transmission itself. External test signals are stored on the test device itself or transmitted to it via mobile phone or NAS server. stute.x1A supports this measuring mode. External measuring signals are available separately.
