Features

• Accomodates virtually any tape reproduce head.

• Low noise design utilizes an optimum combination of IC and discrete circuitry for lowest residual electronics noise.

• Wide equalization adjustment range for both NAB and IEC recording characteristics, 1-7/8 to 30ips.

• Multi-turn trim adjustments and fully regulated power supply assure stability of settings and drift-free operation.

• Entire electronics amplifier subassembly unplugs from the front panel for ease of maintenance.
