Offering the user an unsurpassed level of sonic control, the TranZformer GT combines an API 525 feedback-type compressor with a guitar-optimized 3 band equalizer, both independently in/out switchable. The unit also features phase invert switches on each output, ground lift, clip indicator and transformer output. Like all API products, the TranZformer GT is built to API's exacting standards and remains true to the design philosophy that has made API the leader in professional analog gear for nearly 50 years.

Output connections

1/4" Hi-Z unbalanced output w/ variable level control

XLR Male balanced line output, fixed level

*Balanced line output level is +6dB higher than Hi-Z output with Level control fully clockwise.

Output Impedance:

Hi-Z output: 7.5k

Balanced Line output: Less than 75

Gain Control:

9.2dB - 30dB, Variable, Hi-Z output

15.2dB - 36dB, Variable, Balanced line output

Level Control: -inf. to 0dB, Variable, Hi-Z output only

Maximum output level before clipping

Hi-Z Output: +21dBu

Balanced Line Out: +27dBu

Frequency Response: +0, -0.5, 20-20kHz, both outputs, low-capacitance cable
Noise: -75dBu
THD+N: Less than 0.01%
Tone Control: 200Hz & 1500Hz Peaking, 5kHz Shelving, continuously-variable boost/cut, +/-16dB range.

Compressor

Ratio: Varies from 2: to 20: depending on compressor control setting.

Attack (fixed): Less than 5ms

Release (fixed): 100ms average (frequency-dependent for natural envelope tracking)

Compressor Control (6 Switchable settings): 1 = subtle compression, 6 = maximum compression. Turning clockwise Increases gain reduction (lower threshold) while simultaneously raising output level to match.
