SAFETY PRECAUTIONS

For your safety and the safety of others, be sure to read and understand all safety and opera­tional instructions before attempting to use the TCL-2. WARNING: The TCL-2 internal cir-
cuitry carries lethal voltages. Carefully observe all warnings, precautions, and instructions on
the TCL-2 and as described in the instructions supplied with the unit.

1. WATER, MOISTURE, AND SPILLAGE
Do not attempt to use the TCL-2 in, near, or around water or in unusually moist environments,
such as near a sink or swimming pool. Prevent liquids or any other materials or objects from spill­ing or falling into the TCL-2 unit.

2. HEAT AND VENTILATION
Be sure to allow adequate ventilation to TCL-2 and avoid using or installing unit in close proxim­ity to heat sources, such as heaters, stoves, radiators, power amplifiers, spotlights, or other heat­producing appliances or equipment.

3. POWER SOURCES AND POWER CORD PROTECTION
The TCL-2 Power Supply should be connected to a power source only of the type described in
the operating instructions or as marked on the Power Supply. Route the power cord so that it is
not likely to be walked on or pinched by having objects placed on it. Pay particular attention to
plugs, receptacles, and the point where the AC power cord exits the TCL-2.

4. GROUNDING
For your safety, it is extremely important that the grounding pin of the 3-wire power cable (in­cluded with unit) be inserted into a grounding type 3-pin power outlet. If you are unable to insert
the plug into an existing outlet, contact an electrician to install a properly grounded 3-pin power
outlet, preferably with OFI protection.

5. DAMAGE REQUIRING SERVICE
This unit should be repaired or serviced by qualified personnel whenever:

· The AC power cord has been damaged, or

· Objects have fallen or liquid has spilled into any TCL-2 unit, or

· The unit does not function properly or exhibits a marked change in performance, or

· The unit has been abused, dropped, or damaged, or

· The unit has been exposed to rain or moisture

6. SERVICING
Lethal voltages are found inside the TCL-2 chassis. The user should not attempt to repair or service
this unit. All servicing and/or repairs should be referred to Millennia Media.

If, after reading all instructions, precautions, and warnings, you have remaining questions, please
contact Millennia Media directly before attempting to use your TCL-2. Retain this owner’s manual
as a record of your purchase to aid positive identification in the event of loss.

TCL-2

QUICK START!

READ THIS!! The TCL-2 operates with lethal operating
voltages -- the voltage inside the TCL-2 can kill you. Never,
under any circumstances, remove the top cover. Refer to a
qualified electronics technician any and all servicing, tube
replacement, and other operations which require the top
cover to be removed.

Congratulations on your purchase of the Millennia Media TCL-2 with Twin Topology. The
TCL-2 is the result of meticulous listening tests on numerous circuit, topology, and packaging
designs. Your TCL-2 is a finely tuned instrument intended for critical professional applications
— we feel it is the world's most sonically neutral analog EQ. With the emergence of 24+ bit
digital audio, recording engineers are faced with a new requirement for undistorted dynamic
range. The TCL-2 meets this challenge exceptionally well.

Before connecting power to the TCL-2, assure that the rear panel voltage selection fuse block
switch is set correctly. In the USA, the TCL-2 is shipped with the voltage selection block set to
100-120 VAC. At this voltage setting, a pair of 1 amp 5 x 20 mm slow blow fuses have been
factory installed. If you change the voltage selection block to 200-240 VAC usage, be sure to
change both fuses to 500 milliamp (0.4 amp) slow blow types.

The TCL-2 enclosure measures 19" wide x 3.5" high x 12.5" deep and is designed for mounting
into a standard 2U, 19" equipment rack. If the TCL-2 is mounted in a road case or other rack
which is prone to strong vibration or shock, it is recommended that the rear of the TCL-2 be
supported or otherwise reinforced to withstand such conditions. The TCL-2 requires adequate
ventilation. To assure proper air circulation and operation, leave at least one rack space open
above and below the TCL-2.

The TCL-2 is designed on a common ground topology. For high quality operation, and for your
own safety and the safety of others, do not defeat the purpose of the earth grounding pin on the
A/C power cord!

TCL-2 REAR PANEL

(1) INPUTS "In 1 (Left), In 2 (Right)"

Conventional 3-pin female XLR input jacks for all balanced or unbalanced line level signals. In­put impedance is greater than 10k ohms when "10 dB" gain range switch is engaged (+/- 10dB),
greater than 40k ohms when gain range switch is disengaged (+/- 20dB), and greater than 100k
ohms when optional balanced inputs are installed. Standard TCL-2 line input is unbalanced us­ing pin 1 as chassis ground, pin two as signal, and pin 3 tied to audio ground.

(2) OUTPUTS "Out 1 (Left), Out 2 (Right)"

Conventional 3-pin male XLR output jacks. Output is unbalanced. Pin 1 is chassis ground, pin
2 is signal, and pin 3 is tied to audio ground. J-FET topology output impedance is 55 ohms.
Vacuum tube output impedance is 150 ohms.

(3) EARTH/AUDIO GROUND JUMPER

A barrier terminal which ties earth ground to audio ground. If ground "hum" loops are experi­enced when using the TCL-2, removing this jumper may help. Using this jumper, the integrity
of the chassis/earth ground connection is never compromised.

(4) AC VOLTAGE MAINS SELECTION "100-120" or "200-240"

A power entry module with a removable fuse holder block. This fuse holder block is selectable
for 100 to 120 Volt or 200 to 240 Volt worldwide mains powering. The fuse block contains two
fuses — one fuse is in series with the hot power line while the other fuse is in series with the
neutral power line. Both fuses must be installed. To change the mains voltage selection, remove
IEC power connector and assure that the TCL-2 is not connected to mains power. With a non­conductive tool, gently pry the fuse block away from the power entry module. Remove the
two fuses and replace both with type as shown below. Slide out the internal PC Board, turn it
over, and reinsert the PCB so that the desired AC mains voltage appears in the viewing window.
Double check that the fuses installed correspond to the AC mains voltage range which appears
in the viewing window. Gently push the fuse block back until flush and snug.

FUSES:
For 100-120 VAC mains, use 5x20mm, 1A, slow blow, 250V, Littelfuse 239 or equivalent.
For 200-240 VAC mains, use 5x20mm, 500 mA, slow blow, 250V, Littelfuse 239 or equivalent.

(5) POWER ENTRY "IEC Power Receptacle"

An IEC-type AC line-power receptacle for use with removable cords. Use only the power cord
provided with the TCL-2 unit or equivalent U/L approved type SV, SVT, SJ, or SJT AC power
supply cord. Do not defeat the third pin earth ground! If ground lifting is desired, remove the
Earth/Audio Ground Jumper strap (item number 3, above).

NOTE: Units configured for 200-240 do not have a power cord included. Contact your dealer
or distributor for a cable appropriate for your country.
