APEX(Audio Products of Excellence)사는 품질을 우선으로하는 이름 그 자체에 의미를 담고 있습니다. APEX사는 1990년 이후 프로오디오 시장을 시작으로 PE-133 싱글 디바이스에 그래픽EQ와 멀티 파라미터/놋치 필터를 내장한 제품을 시작, 파라그래픽EQ 역시 시장에 첫선을 보였습니다. APEX의 목표는 항상 음향의 고품질을 위한 혁신적인 디자인의 아날로그 및 디지털 제품개발에 있습니다. 풍부한 경험자와 젊은 엔지니어로 구성된 팀웍을 바탕으로 현 프로오디오 시장에서 오늘도 새로운 제품개발을 위해 노력하고 있습니다.

  • Professional quality and reliability
  • Mute control for each input and output section
  • Mono sum for each input and output section
  • Comprehensive LED metering, with Clip indication
  • Electronically balanced inputs and outputs (XLR connectors throughout)
  • RF filtering on audio I/O and mains supply
  • Universal switch-mode power supply
  • Optional front panel guard for security


Each stereo input provides clear and precise LED metering, with the addition of Mute, Mono Sum and gain adjustment facilities. Similarly, each stereo output section comes fitted with identical features, with the addition of independent mix controls for both stereo inputs, allowing unique stereo mixes to be sent to each output.

The dBZ-48 provides the versatility to be employed in many situations.

For security purposes, an optional front panel guard is available to prevent anyone from tampering with the dBZ-48 controls.

As found with all Apex products, audio quality and reliability are of primary importance. The dBZ-48 continues this philosophy with very low noise and distortion figures, immunity against external RF sources and electronically balanced I/O (enabling long cable runs to be achieved with minimal signal degradation).

Zone Mixer
The dBZ-48 allows installers to mix two stereo sources (for example, a multi-disc CD player and a hard disk based playout device) to four separate zone outputs.
The four stereo outputs can then be wired to active speakers, amplifiers or speaker management systems in each zone.

The dBZ-48 can quickly be configured to provide mono outputs if required without the need to alter any internal parameters.

Stereo Distribution Amplifier
It is now a common requirement to distribute a single stereo source to multiple destinations, whether they be to rooms in an installation or theatre, to FOH and Monitor consoles or for dedicated broadcast or recording feeds. The dBZ-48 comfortably provides this functionality in a way that is simple, effective and quick to configure.

Stereo Merge
In many situations there is a requirement to merge multiple stereo sources. It may be the case that in a live environment the output of two FOH consoles need to be merged together. Alternatively there may be a requirement to free channel resources on a FOH console by removing any CD or hard disk playout device. The solution is to mix these sources together within the dBZ-48. By using the dBZ-48 the process is quick and efficient.
