SPK-OCA504 - Overview 

 

Overview 

The 

SPK-OCA504 

is a powered two-way speaker system designed for indoor wall 

mounting. The system accepts a line level stereo input and amplifies it using a 
built-in amplifier and outputs a speaker signal to the passive speaker. 

The 

SPK-OCA504 

speaker system features: 

 

Three available inputs (that can either be connected separately or 
connected simultaneously to form a mix of the inputs) that consist of: 

 

A Line level unbalanced stereo audio input on a 3.5mm mini jack 
connector 

 

A balanced stereo audio input on a 5-pin terminal block connector 

 

An unbalanced stereo audio input on two RCA connectors 

 

An output to external amplified or non-amplified speakers 

 

An output to an external sub-woofer  

 

A unique looping output, letting you chain additional pairs of active and 
passive speakers 

 

TREBLE, BASS and VOLUME control knobs  

 

A control panel on the back of the active speaker that controls all the 
functions of both speakers 

 

A magnetic shield 

 

Enhanced bass reflex design 

 

An integrated 2x30W stereo amplifier (no external amplifier required) 

 

A self adjusting power range of 90 to 240V AC  

 

Auto-power shutoff 

The 

SPK-OCA504 

is enclosed in an ABS cabinet and can be mounted indoors on 

the wall, vertically or horizontally. The mounting brackets are made of hardened 
steel that attach to each speaker, letting you rotate each speaker to the left or 
right.
