Pembesar suara dikawal dengan alat kawalan jauh.

Pembesar suara literally means something like sound enlarger/amplifier.

It is built from:

• besar = big
• pembesar = something that makes something bigger / an enlarger
• suara = sound, voice

So pembesar suara is the standard Malay term for a loudspeaker/speaker. Even though the literal meaning sounds different from English, this is the normal expression.

Because this sentence is in the passive voice.

• mengawal = to control
• dikawal = is controlled / being controlled

So:

• Alat kawalan jauh mengawal pembesar suara. = The remote control controls the speaker.
  (active)
• Pembesar suara dikawal dengan alat kawalan jauh. = The speaker is controlled with a remote control.
  (passive)

Malay often uses di- to form the passive when the thing receiving the action comes first.

In this sentence, di- marks a passive verb.

• kawal = control
• dikawal = controlled / is controlled

So di- here is not the preposition di meaning at/in/on. They just happen to look the same in writing.

Compare:

• di rumah = at home
  Here di is a preposition and is written separately.
• dikawal = controlled
  Here di- is a prefix and is written together with the verb.

That spelling difference is important.

Here dengan means with / by means of and shows the instrument used.

So:

• dikawal dengan alat kawalan jauh = controlled with a remote control

This is not the same as with meaning together with someone in English, although Malay also uses dengan in that sense in other contexts. Here it clearly means using something.

It breaks down like this:

• alat = tool, device
• kawalan = control
• jauh = far, distant

So alat kawalan jauh literally means far-control device, which is the Malay way to say remote control.

A useful pattern here is:

• kawal = control (verb)
• kawalan = control (noun), the act/system of controlling

So alat kawalan is a control device, and jauh specifies that it works from a distance.

Because kawalan is the noun form.

• kawal = to control
• kawalan = control / regulation / system of control

Malay often uses the suffix -an to make a noun from a root.

So:

• alat kawal would sound incomplete or unnatural here
• alat kawalan jauh is the standard noun phrase for remote control

It could be singular or plural depending on context. Malay nouns usually do not change form for number.

So pembesar suara can mean:

• the speaker
• the speakers
• a speaker

If the speaker wants to make the plural very clear, Malay can use:

• repetition: pembesar-pembesar suara
• a number: dua pembesar suara
• a context clue

But in normal sentences, number is often left unstated.

Because Malay does not normally use articles like English a/an/the.

So:

• Pembesar suara can mean a speaker, the speaker, or speakers, depending on context.

Malay usually lets the listener figure this out from the situation. If needed, it can be made more specific with words like:

• sebuah = a / one (for certain objects)
• itu = that / the one mentioned
• ini = this

For example:

• Pembesar suara itu = that speaker / the speaker
• Sebuah pembesar suara = a speaker

Yes, the sentence does not say who is doing it. It only says what instrument is used.

• Pembesar suara dikawal dengan alat kawalan jauh.
  = The speaker is controlled with a remote control.

This focuses on:

1. the thing affected: pembesar suara
2. the method/instrument: dengan alat kawalan jauh

If you want to mention the doer, you could say something like:

• Pembesar suara itu dikawal oleh pengguna dengan alat kawalan jauh.
  = The speaker is controlled by the user with a remote control.

Here:

• oleh = by (introducing the agent/doer)

But Malay often leaves the doer out if it is obvious or unimportant.

Yes. A natural active version is:

• Alat kawalan jauh mengawal pembesar suara.
  = The remote control controls the speaker.

Or, if a person is the one using the remote:

• Pengguna mengawal pembesar suara dengan alat kawalan jauh.
  = The user controls the speaker with a remote control.

The passive version is useful when the speaker wants to emphasize the speaker rather than the controller.

It is the standard formal/native Malay term, especially for loudspeaker.

But in everyday speech, many people also use English loanwords such as:

• speaker
• sometimes speaker audio, depending on context and region

Still, pembesar suara is the safest standard Malay choice, especially in writing, education, manuals, or formal contexts.

A rough guide for an English speaker:

• Pembesar ≈ pem-buh-SAR
• suara ≈ soo-A-ra
• dikawal ≈ dee-KA-wal
• dengan ≈ duh-NGAN
• alat ≈ A-lat
• kawalan ≈ ka-WA-lan
• jauh ≈ JAUH

A few helpful notes:

• r is usually tapped/trilled lightly
• ng in dengan is like the ng in sing
• jauh has two vowels in sequence, something like jow-uh or jauh

A natural full rhythm would be: pem-buh-SAR soo-A-ra dee-KA-wal duh-NGAN A-lat ka-WA-lan JAUH
