Connection

The 786 is the perfect partner for your microphone, providing you with two channels of audio purist

quality preamplification. The 786 delivers up to 70dB of sonically transparent gain to reveal the detail

and audio signature of even the most esoteric studio mics. It transforms their low level output signal to

a clean high level, high current output for direct connection to the line level inputs of your mixer, DAT

machine, sampler, or any other recording medium that accepts line level, analog input.

1. Bypassing a console's preamp with the 786.

1. Mount the 786 in a 2U rack space. The 786 requires a two rack-space height and a standard

19 inch rack-space width. It can be mounted above or below anything that doesn't obstruct

the vents of the 786. Ambient temperatures should not exceed 95°F (35°C) when equipment

is powered.

2. Make sure that AC power is not connected to your 786.

3. Connect your mic cables to the audio inputs of the 786.

4. Set the front panel of the 786 to the desired settings, including phantom power and Low-Z.

Connect the audio output of the 786 to the console's LINE INPUT, and ensure that the con-

sole's input selection switch is set to LINE, and the console's gain control is set at its nominal

operating level (ie: +4dBu).

NOTE: If you are using a mic with a separate power supply, such as a tube microphone, make sure that you are

not sending +48V phantom power from the 786 to the mic. Use the +48V Phantom Power switch on the 786

for all other microphones which require phantom power.

5. Turn the 786's large Gain control counter-clockwise to the +15dB position, and the Fine con-

trol to 0dB, and apply power to the 786. Make sure your console's gain slider is at approxi-

mately nominal level ("0dB") and begin to slowly increase the gain of the 786 using the large

Gain control. You should increase the gain until the recording device is operating at nominal

signal input level. Refer to Figure 2 below for hooking up the 786 to a console.
