Thank you for choosing a dBTechnologies Product!

The new SUB 618 is an active subwoofer. It is equipped with one 18” transducer (2.5” voice coil).
It is portable, thanks to the compact size, low weight and the convenient handles.
It allows a mono or stereo input and output connection, and a complete configuration with different parameters
controls. Thanks to the settings of polarity, low-frequencies enhancement, and of possible crossover filtering in
output, it is possible to use it in different scenarios. A typical configuration is the matching with B-Hype and Opera
series speakers, thanks to the M20 pole mount on the top. The subwoofer is also stackable.

1) Unpacking

The box contains:
N°1 SUB 618
N°1 Mains cable (VDE)
This quick start and warranty documentation

2) Easy installation

SUB 618 is equipped with:

A – Houses for stack mounting
B – M20 pole mount

C – Handles (1 x side)

NEVER USE THE HANDLES TO SUSPEND
THE SPEAKER!

Those mechanical particulars were thought for an easy
use and for different configuration needs.

In the pictures above are shown two examples of
configuration for the use of SUB 618.
The matching with a speaker (like one of the OPERA or
B-HYPE series) allows a perfect performance in an
extended frequency range. SUB 618 is perfect for
gigging bands, like for small-medium venue
installations. The mechanical houses on the top of the
subwoofer cabinet allow the stacked use.

4 – Outputs Mode (Link or Xover mode)
5 – Subwoofer Setup (Polarity switch) and

Subwoofer Mode button (Flat/Boosted)

6 – LEDs (Limiter, Signal / ON)
7 – Mains input connector
8–Power switch (ON, OFF)

configuration (see also the complete user manual and
accessories instructions for further information),
connect the audio input (mono) or inputs (stereo) (1).
Connect the output (mono) or outputs (stereo) (2) and
consequently set the Subwoofer level to 0 dB in the
right position (3).

b) Set properly the Outputs Mode (4), (“Link” in case of
direct link connection, “Xover” in case of 120 Hz
crossover, for example when in use with a OPERA or B­HYPE series model).

c) Choose the Subwoofer Polarity (Normal or Reverse)
(5) to obtain the proper behavior. It is possible to add
a low-frequencies boost (5) with the related Subwoofer
Mode switch.

d) Connect the VDE cable to the related connector (7).
Then turn ON the power switch (8). The, the
“Signal/ON” LED (6) turns on, signaling the proper
