Yes, that’s correct. Though the spectrum used is something that should always be pointed out. One DAB+ block (transmission signal or mux) has a fixed on-air signal width of about 1535 kHz (1.5 MHz). In DRM, one block (or mux) has a fixed on-air signal width of 100 kHz (the same in VHF bands II/FM-band and band-III) which is incidentally half the analogue FM spectrum of 200 KHz. Each DRM block carries up to 3 (between 0 and 3) audio services (with PAD data each) plus 1 dedicated data service.

However, for efficient transmission setups, multiple such DRM blocks from one single or even several independent broadcasters can be placed side-by-side in the spectrum (one block every 100 kHz) and all the blocks can be broadcast from a single transmitter (in band II and III).
