SAFETY WARNINGS

Intended to alert the user to the presence of uninsulated ‘Dangerous Voltage’ within the products enclosure that may be sufficient to constitute a risk of electrical shock to persons.

Intended to alert the user of the presence of important operating and maintenance (Servicing) instructions in the literature accompanying the product

CAUTION: Risk of electrical shock – DO NOT OPEN.
To reduce the risk of electrical shock, do not remove the cover. No user serviceable parts inside. Refer servicing to qualified personnel.

WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance please read the operating instructions for further warnings.
WARNING

After unpacking your amplifier check that it is factory fitted with a three pin ‘grounded’ (or earthed) plug. Before plugging into the power supply ensure you are connecting to a grounded earth outlet.

GENERAL INSTRUCTIONS

In order to take full advantage of your new product and enjoy long and trouble-free performance, please read this owner’s manual carefully, and keep it in a safe place for future reference.

Unpacking: On unpacking your product please check carefully for any signs of damage that may have occurred whilst in transit from the HH factory to your dealer. In the unlikely event that there has been damage, please re-pack your unit in its original carton and consult your dealer. 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, 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, tape decks, cd players, 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 bass 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 bass 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.
Servicing: The user should not attempt to service these products. Refer all servicing to qualified service personnel.

The U.S. Government’s Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures: According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Earplugs or protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation.
Symbols & nomenclature used on the product and in the product manuals, intended to alert the operator to areas where extra caution may be necessary, are as follows:

INTRODUCTION

The TNA-2120SA active subwoofer features dual HH custom designed 12-inch low frequency drivers and three channel Class D amplifier. Totaling 4800 watts (peak), the TNA-2120SA is capable of not only powering the internal dual driver subwoofer, but via two full-range outputs, powering up to 6 x TNA-2051 mid/high enclosures simultaneously. Achieving a max SPL of 137dB with a frequency response of 52Hz – 20KHz (-10dB) with TNA-2051 fitted.

6 expertly crafted DSP modes efficiently optimise the audio response of the system to meet the user’s needs. Whether that’s ground stacked flat response, or flown with subtle bass lift, the TNA-2120SA comes equipped to support multiple applications, venues, and events as either a portable or suspended loudspeaker system.

The acoustically optimised, 15mm plywood enclosure includes 8 x M8 Integrated fixing points, that allow suspension via the TNA-BRK1 bracket (available separately) for an installed live sound solution. Alternatively, linking with the TNA-DF1 dolly frame, transforms the TNA-2120SA in to an easily transportable, live sound system. A perfect solution for rental companies and non-fix installations.

GETTING STARTED

This manual contains important information regarding correct and safe operation of your TNA system. Please read it thoroughly in order to get the best performance and reliability from your HH product.

POWER CYCLE

Many products have large transient surges at turn on and off which can cause damage to your speakers. Following the sequence below for power-up and the reverse for power down will prevent this from occurring:
POWER CYCLE

CONTROL PANEL

INPUT: Accepts a balanced/unbalanced line level XLR terminated signal.
VOLUME: Controls the overall output level of the TNA-2120SA and the level present at FULL RANGE OUTPUT-A and FULL RANGE OUTPUT-B.
MUTE / PROTECT INDICATOR: This illuminates if a fault condition occurs. In this instance, the amplifier will shut down to prevent further damage. Normal operation will resume once the fault condition has been rectified.
PLEASE NOTE: On power down, the MUTE/PROT indicator will illuminate to indicate the system is muted.At this point it is safe to disconnect any cables.
POWER INDICATOR: Illuminates when the unit is connection to the main supply and switched on.
CLIP: The led illuminates if any of the in-circuit limiters are triggered.
Reduce the VOLUME control to rectify this.
LINK OUT: A balanced output linked directly from the INPUT.
PRESET SELECT and STATUS INDICATORS:

The onboard DSP optimises the equalisation characteristics for both FULL RANGE-A and FULL RANGE-B outputs. Cycle through the presets via the PRESET button, in conjunction with the DSP PRESET chart.
1A: FULL RANGE OUTPUT-A, optimised for 2 x TNA-2051, 0° tilt.
1B: FULL RANGE OUTPUT-B, optimised for 2 x TNA-2051, 0° tilt.
2A: FULL RANGE OUTPUT-A, optimised for 2 x TNA-2051, 8° tilt.
2B: FULL RANGE OUTPUT-B, optimised for 2 x TNA-2051, 8° tilt.
3A: FULL RANGE OUTPUT-A, optimised for 2 x TNA-2051, 0° tilt.
3B: FULL RANGE OUTPUT-B, optimised for 2 x TNA-2051, 8° tilt.
4A: FULL RANGE OUTPUT-A, optimised for 3 x TNA-2051, 0° tilt.
4B: FULL RANGE OUTPUT-B, optimised for 3 x TNA-2051, 0° tilt.
5A: FULL RANGE OUTPUT-A, optimised for 3 x TNA-2051, 0° tilt.
5B: FULL RANGE OUTPUT-B, optimised for 3 x TNA-2051, 8° tilt.
6A/B: FULL RANGE OUTPUT A/B, full range outputs for use with loudspeakers of your choice.

GROUND LINK: Is used to reduce the potential problem of earth loops when connecting to other equipment via the LINK OUT.
The control isolates/connects signal ground to safety ground of the LINK OUT XLR.
SUB OUT: A balanced line level signal for connecting additional active cabinets or a feed to a in-house PA system.
THIS OUTPUT CANNOT DIRECTLY DRIVE A LOUDSPEAKER.
MODE: It is important to set the mode switch properly to get the best performance from the system. When the mode switch is set to LINE OUT, the XLR out is a full range line level signal, when the mode switch is set to Sub Out, the XLR out has a low pass filter applied for direct connection to another powered subwoofer.
PLEASE NOTE: When set to SUB OUT, the internal woofers also have a Hi- pass filter applied, effectively making a true three-way system. If no external subwoofer is used, be sure to leave this switch set to LINE OUT mode.
FULL RANGE – A/B: Two high power outputs via speakON compatible connectors.
Each output is driven via its own amplifier channel and is capable of driving into a 4 Ohm load or greater.
Always connect the LOUDSPEAKER-A OUTPUT to the Input of the TNA-205I which is physically closest to the TNA-2120SA. The DSP Presets have taken proximity into account and offer subtle differences in the FULLRANGE A and B outputs.
POWER SWITCH: Turns the system On and Off. Ensure the VOLUME control is set to minimum when switching the unit On or Off.
TWIST LOCK MAINS POWER INLET: Connect the included PowerCON compatible mains lead here. The TNA-2120SA contains a universal mains power supply, and will operate from 100V~ to 240V~. Ensure the mains cable is earthed.
VENTILATION SLOTS: To ensure prolonged and reliable use. DO NOT block or obstruct the ventilation slots on the rear panel.
PLEASE OBSERVE THE PANEL SAFETY WARNINGS!
