SAFETY & OPERATING PRECAUTIONS

Important symbols:

This symbol appearing on the product or in this manual indicates the presence of dangerous voltage within the product enclosure that presents the risk of electric shock injury. When this symbol appears next to an operation discussed in this manual, only qualified technical personnel should perform that operation.

This symbol indicates important operating or maintenance instructions that should be read carefully. Failure to observe these instructions could result in damage to this product or other equipment.

WARNINGS:

While no hazardous voltage is present within this product during normal operation, please observe the following warnings regarding any AC-powered equipment into which this product is installed:  To reduce the risk of electric shock injury, do not remove the access

covers on AC-powered equipment. Refer servicing to qualified personnel.

 This unit is intended for indoor operation only  Do not operate this unit in the presence of rain, liquids or condensing

moisture.

 Do not expose the unit to dripping or splashing liquids.  Do not place liquid-filled objects on the unit.  Do not defeat the earth ground connection in the AC power cable.  Do not defeat intended AC power connection polarization.  Do not use a damaged or excessively worn cord to connect the equipment

to AC power.

CAUTIONS:

 Severe damage to pT2-500 will occur if incorrect power supply voltages

are applied to the card edge connector. Please consult the “CONNECTIONS” section in this manual for proper power supply specifications/connections.

Disclaimer: Product failure caused by improper voltage application cannot be covered under warranty.

 Liquid entering the product enclosure is likely to cause performance

degradation or failure. Failures due to moisture entering the enclosure cannot be covered under warranty. Should liquid spill on the unit, immediately disconnect it from the AC power source and contact TRUE Systems for servicing instructions

 This product is designed to operate in an ambient temperature range of

10C to 50C (50F to 122F).

PRODUCT OVERVIEW

Thanks for using our product! We appreciate the confidence you place in TRUE Systems by purchasing the pT2-500 microphone preamplifier/instrument DI. We

design our products to deliver stunning musical accuracy, uniquely useful features, exceptional value, and reliability. Every aspect of this product design was determined by careful listening tests and extensive user feedback. Please feel free to contact us with questions or comments. And, we always appreciate hearing about (and hearing) successful projects you’ve completed!

NEW TYPE 2 CIRCUIT DESIGN

The pT2-500 is the first instance of our new-technology Type 2 circuit design. Our Type 2 design provides the traditional ultra-resolution musicality of our original design

preamps, but adds serious analog depth and warmth. In short: It sounds BIG!

New technology alone certainly doesn’t guarantee better sonic performance (frequently, just the opposite). But, frankly, neither do transformers, Class A circuit topology, through-hole components, etc., etc. We’ve spent great effort designing, refining, and working with major component manufacturers in order to implement the Type 2 design. And, we believe you’ll be very pleased with the results!

FEATURES

 API™ 500 series module format  Totally Balanced Topology for:

 insensitivity to ground noise/loops  Insensitivity to EMI, both external and from adjacent modules/power supplies  reduced distortion

 Rail-to-Rail design for:

 higher internal headroom  higher maximum input level without pad (up to +22dBu)  higher output level without transformer and excessive power supply current

 0.1% precision resistors for:

 exceptional Common-Mode and Output Signal Balance performance  excellent unit-to-unit sonic consistency

 “Real DI” IN and THRU jacks for:

 Easy hookup to amps for simultaneous DI and amp’d tracking or live sound  Easy hookup to other DI’s or effects for simultaneous tracking or live sound

 Detented, continuous Gain Control and Dual Gain Ranges for:

 easy gain resetability  easy gain setting over wide gain ranges

 Steel Enclosure for:

 protection from EMI and RFI  protection from ESD and handling contamination/damage

 80Hz High Pass Filter  4-Level Signal Meter
