Line v Speaker Connections
B.Sc. (Hons) Multimedia Computing
Media Technologies
Speaker output signal has volume and bass/treble modifications - poorer quality for recording
Line connectors provide a flat signal without any added amplification (gain) or eq. i.e ‘flat’

Speakers
B.Sc. (Hons) Multimedia Computing
Media Technologies
Room acoustics very important Reference or ‘monitor’ speakers - tell it like it is’
i.e. give no coloration from hardware eq. Headphones - can be accurate way to monitor
sound quality - but speakers considered best sound monitoring device

Dynamic Microphones
B.Sc. (Hons) Multimedia Computing
Media Technologies
Versatile and ideal for general-purpose use. Use a simple design with few moving parts. Sturdy and resilient to rough handling. Better suited to handling high volume levels,
such as from certain musical instruments or amplifiers.
No internal amplifier and do not require batteries or external power.
Microphones: Dynamic
B.Sc. (Hons) Multimedia Computing
Media Technologies
Condenser Microphones
B.Sc. (Hons) Multimedia Computing
Media Technologies
Condenser microphones require power from a battery or external source.
Audio signal is stronger signal than that from a dynamic.
More sensitive and responsive than dynamics
Good for capturing subtle nuances in a sound.
Microphones:Condenser
