Shadow Hills Industries / Hammer Forged Mono GAMA

The Shadow Hills Industries Hammer Forged Mono GAMA is a new Mono Gama (Golden Age Microphone Amp) featuring innovative technology developed by engineers at the Shadow Hills Austin Research Facility.

■ Microphone Preamplifier

■ API 500 Series Module

This model incorporates Shadow Hills' proprietary ""Stack Technology"" and ""Transformer Switching Matrix,"" amplifying microphone and unbalanced signals to the highest level for superior sound quality.

It can process signals appropriately and output them optimally even in the most demanding environments.

■ Microphone Level Control

At the heart of the Mono GAMA is a Shadow Hills discrete operational amplifier. This amplifier, with its uncompromising design, delivers high resolution and sonic depth across a wide frequency range. It is particularly characterized by its clear sound and excellent transient response, ensuring maximum performance in any recording environment.

■ Gain Control

Equipped with a rotary attenuator, the amplification level of the signal input from the microphone or line can be easily adjusted with a rotary knob.

Turning clockwise increases the gain, and turning counterclockwise decreases the gain.


■Channel Controls

The Mono GAMA features phantom power, polarity (polarity reversal), and attenuation functions.

Phantom Switch: Supplies the 48V phantom power required for condenser microphones.

Polarity Switch: Reverses the polarity of microphone and line signals, useful for phase adjustment during recording and mixing.

Attenuate Switch: Allows adjustment of input signal volume via a balanced attenuator.

- Microphone Input: -18dB attenuation

- Line Input: -8dB attenuation

All input signals pass through transformer coupling and are output through Shadow Hills' proprietary transformer switching matrix.

■Output Transformer Switching Technology

Equipped with a proprietary transformer switching matrix, the characteristics of the output transformer can be changed by switching a switch. This allows for free customization of frequency response and distortion characteristics, enabling sound shaping tailored to your application.


■Four Transformer Settings

- Nickel Transformer

Achieves low distortion and flat low-frequency characteristics

Upper bandwidth: 1dB bandwidth at 10kHz

- Discrete

Transformerless position

Achieves extremely clear and uncolored sound

Ultra-fast transient response

- Steel Transformer

The most colored sound

Tight curve with a +1dB boost at 40Hz

Sound quality changes significantly depending on the programmed material

- Stack

A fusion of nickel and steel transformers

Produces stronger saturation and harmonics, providing a distinctive sound

■Durability and Practical Design (Operative Deployment)

Shadow Hills engineers conducted thorough durability testing on the Mono GAMA design to ensure optimal performance in all environments. As a result, it boasts superior durability and is designed to withstand harsh operating conditions.

The Shadow Hills Hammer Forged Mono GAMA is a professional preamp that delivers top-tier sound quality and flexibility for recording and mixing. With four transformer settings and high-quality discrete operational amplifiers, it allows you to create the optimal sound in any environment.
