Brooks RM 909 Jam Sync

A generation of new SMPTE according to the input SMPTE signal

Grouping
1) Controlling the gain of several individual channels with a Group Fader.
2) The mixing together of several individual audio signals to send a mixed signal out of the console to record a track on a multitrack tape machine.

Brooks Hi Fi speakers Absorption
Short for the term Acoustical Absorption (quality of a surface or substance to take in, not reflect, a sound wave).

Balanced input/output
A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example.

Brooks RM 909 reviews House Sync
A synchronization signal such as SMPTE time code that is used by all recorders in the control room.

Hearing Limitation
An inability of the ear to hear important characteristics of sound under certain conditions. Characteristics that can be affected include pitch, level, clarity, presence and direction.

Error Concealment
Putting replacement information bits into a digital audio signal to replace lost bits when the digital recording or processing system cannot verify whether the lost bits were l's or 0's but can make a good guess by comparing the known bits that were close in position to the lost bits.

Line Level
1) An amplified signal level put out by an amplifier and used as the normal level that runs through the interconnecting cables in a control room.
2) A low level signal such as the signal in a guitar cord. Most parts of a PA require a line level signal. Remember, however, that speaker outputs are not line level. Plugging speaker outs into line ins will result in damage to the equipment
