The Yamaha HA8 is an 8-channel balanced microphone and line amplifier designed primarily to add versatile input capability to Yamaha DMP-series Digital Mixing Processors and DMR Digital Multitrack Recorders. It features individual channel mute switches, switchable phantom power for condenser microphones, a five-position pad switch, and a 30 dB gain control per channel.
| Total Harmonic Distortion (Max Gain) | Less than 0.05 % |
|---|---|
| Hum & Noise | -128 dB (58 dB S/N) |
| Maximum Voltage Gain | 74 dB |
| Power Requirement (US/Canada) | 120 V AC, 60 Hz |
| Dimensions (W x H x D) | 480 x 88 x 338 mm |
It acts as the master phantom power switch for all 8 channels and should only be turned ON when using phantom-powered condenser microphones.
The five-position pad switch inserts attenuation prior to the head amplifier, allowing input sensitivity to be varied over an extremely wide range.
A lit or flashing red LED indicates that the signal level is 3 dB below clipping, meaning there is a danger of overloading and distorting that channel.
