Kelantangan mikrofon itu rendah.

Kelantangan means volume, loudness, or sound level.

It comes from the root lantang, which is related to being loud or clearly audible. The pattern ke-...-an often turns a root into an abstract noun, so kelantangan becomes something like loudness.

In everyday Malay, people also very often use the loanword volume, especially for devices:

• Volume mikrofon itu rendah.

That is very natural too.

Malay often leaves out the verb to be in simple sentences like this.

So:

• Kelantangan mikrofon itu rendah.

literally looks like:

• Volume microphone that low

but it naturally means:

• The microphone's volume is low.

This is normal Malay sentence structure. You do not need a separate word for is here.

In more formal language, you may sometimes see adalah, but in a sentence like this, leaving it out is completely natural.

In Malay, demonstratives such as ini and itu usually come after the noun.

So:

• mikrofon itu = that microphone
• buku ini = this book

That is the normal order in Malay, even though English puts this/that before the noun.

Literally, mikrofon itu means that microphone.

However, in real usage, itu can sometimes make a noun phrase feel definite, so depending on context, English may translate it as either:

• that microphone
• the microphone

So in this sentence, both of these English ideas can fit:

• That microphone's volume is low
• The microphone's volume is low

The exact choice depends on context.

This is a noun phrase where one noun is followed by another noun to show a relationship like of or possession.

So:

• kelantangan mikrofon = microphone volume / volume of the microphone

Then:

• mikrofon itu = that microphone

So the whole phrase:

• kelantangan mikrofon itu

means:

• the volume of that microphone
• that microphone's volume

Malay often expresses these relationships without an apostrophe or the word of.

Rendah means low, especially for level, value, height, intensity, or amount.

That makes it a good choice for things like:

• volume
• prices
• temperature
• levels

So kelantangan ... rendah naturally means the volume is low.

Learners sometimes wonder about words like perlahan or kecil:

• perlahan usually means slowly or soft/quiet in some contexts
• kecil means small

For a measurable audio setting or sound level, rendah is a very natural choice.

Yes. That is very natural, and many speakers would probably say it that way in everyday life.

Compare:

• Kelantangan mikrofon itu rendah.
  More fully Malay, a bit more formal or textbook-like.
• Volume mikrofon itu rendah.
  Very common in everyday and technical contexts.

Both are correct.

In this sentence, itu most naturally describes mikrofon.

So:

• mikrofon itu = that microphone

That means the sentence is talking about the volume belonging to that microphone.

If you wanted itu to refer to kelantangan, you would normally say:

• Kelantangan itu rendah.
  = That volume is low.

So word placement matters.

Yes, it is grammatical and natural.

In casual speech, many speakers might use:

• Volume mikrofon tu rendah.

Here, tu is the spoken, informal version of itu.

So you may hear:

• Kelantangan mikrofon itu rendah.
  more standard
• Volume mikrofon tu rendah.
  more casual and conversational

Both communicate the same basic idea.

Yes, depending on context, it can suggest either:

• the microphone's output level is low
• the microphone volume setting is low

Because kelantangan refers to volume/loudness, the sentence focuses on the sound level associated with the microphone.

If someone wanted to be more specific, they might say something like:

• Tetapan volume mikrofon itu rendah.
  = That microphone's volume setting is low
• Suara daripada mikrofon itu perlahan.
  = The sound from that microphone is soft/quiet

So the original sentence is natural, but context tells you exactly what kind of low volume is meant.
