CONTROLS
-
INPUT SENSITIVITY
This control sets the input sensitivity of the TNA-2800SA. Turned fully anti- clockwise, the system will accept a nominal +10dB signal such as that from a high output mixing console, whereas when set to 0dB it is more suited to lower-level inputs such as those from PA link outs. +10dB sensitivity is recommended for most setups. Increase if you need more volume. -
STATUS LEDs
4 LEDs for each woofer, A and B. Power, signal present, protect system and limiter are all highlighted by their respective LED. -
CROSSOVER SELECTOR
Adjust the full range frequency limit of the sub from 70Hz (fully anti- clockwise) to 120Hz (fully clockwise). A full range setting is also included to aid setup and troubleshooting. -
PHASE SWITCH
Switch the signal phase of the output between 0˚ and 180˚, with respect to the input signal. Swap the phase to better integrate the subwoofer into a full speaker system and keep it in phase with the rest of the speakers. Useful when the sub is positioned in a
corner for example. Link out is not affected by this. -
DELAY CONTROLS
Add a delay to your signal if required to keep the sub in sync with the rest of the sound system. Two switches are provided, with the left controlling the delay in milliseconds and the right in microseconds. Can also be used to implement a cardioid function along with the phase switch, multiple subwoofers required.

range frequency response. -
USB-B SOCKET
This socket is for service updates only and is typically not to be used. -
POWER SOCKET
Connect the provided twist lock power cable here to power the subwoofer from mains power. Note, as this system is typically wired into a distribution system, we only provide the actual twist lock power connector socket, and any mains wiring must be made by the end user. Mains voltages are deadly, and all wiring must be performed by qualified personnel only. If in doubt consult a qualified electrician.
TWIST LOCK POWER CONNECTOR WIRING INFORMATION
The TNA-2800SA comes with an unterminated twist lock power connector
compatible connector. It is the user’s responsibility when making the mains
cable assembly to ensure the wiring conforms to local regulations / codes. It
is vital that cable of suitable gauge is used. INSTALLATION
Installation of the product should only be carried out by qualified installers. Do not attempt any rewiring or reconfiguring if you do not possess the relevant training.
Carefully unpack your TNA-2800SA and check that no damage has occurred during transportation.

WARNING: Due to the heavy weight of the product, at least two persons are required to move and install the TNA-2800SA.
The TNA-2800SA comes with four heavy duty castors and fixing screws. If the amplifier is to be a portable system, it is recommended to fit these for easy transportation.
Connect the input socket to either your signal source or a link out from another speaker.
Select your required phase and delay to ensure the subwoofer is kept in phase with the rest of the system. Note that the placement of the product and the direction it faces, compared to the other speakers, will determine how out of phase the output initially is and a verification measurement is recommended.
Finally, when the input is connected, and all rear panel settings are correct, follow the power cycle below to power up the 2800SA.
POWER CYCLE
The TNA-2800SA is a very powerful subwoofer, and when powered on with a signal present, can be affected by transient surges that could damage the speakers.
To ensure this doesn’t occur, follow the sequence below when powering on (and in reverse for powering off):- Ensure power switch is off.
- Connect to power by plugging in the twist lock power cable and turning the mains switch on.
- Connect the input signal, ensuring it is muted and turned to its lowest setting.
- Power the subwoofer on.
- Set the input sensitivity to the required level.
- Unmute the audio source and slowly increase the level.

We strongly advise you to keep your original transit carton, since in the unlikely event that your unit should develop a fault, you will be able to return it to you dealer for rectification securely packed.
-
Amplifier Connection: In order to avoid damage, Generally it is advisable to establish and follow a pattern for turning on and off your system. With all system parts connected, turn on source equipment, mixers, effects processors etc, BEFORE turning on your amplifier. Many products have large transient surges at turn on and off which can cause damage to your speakers. By turning on your amplifier LAST and making sure its level control is set to a minimum, any transients from other equipment should not reach your loud speakers. Wait till all system parts have stabilised, usually a couple of seconds. Similarly when turning off your system always turn down the level controls on your amplifier and then turn off its power before turning off other equipment.
-
Cables: Never use shielded or microphone cable for any speaker connections as this will not be substantial enough to handle the amplifier load and could cause damage to your complete system. Use good quality shielded cables everywhere else.
