!10 dB external volume control.
AMlO/20B - As version A but the gain can be reduced to
completely eliminate the signal. Used in
AMlOP/21.
AMlO/20C - Reconfigured as a single channel bridged
amplifier with auxilliary centre tapped high
impedance output. Used in DK4/44 Conductor's
Desk.

Headphone Monitoring Amplifier. Dual Stereo Headphone
Amplifier for artists in Studios. Incorporates independant
volume controls and input selector switches for each
amplifier. A pair of headphones is plugged into a standard
PO jack inside the lid of the unit and after being clamped
securely by an adjustable P clip emerges through a slot at
each end thus preventing the loss of the headphones. An
auxilliary jack on each end of the uni t allows a second
pair of headphones to be connected for test purposes or a
loudspeaker amplifier to provide locally derived
loud speaking cue/foldback. The unit consists of a diecast
box mounted on a modified microphone. A multipair cable
emerges through the base of the stand and carries 24 V dc
and 3 stereo programme feeds to the unit. The cable is
typically 8 m long and terminates in either a Varicon 38 or
26 pole OB bayonet plug. It is in any case easily removed.
Originally intended for SSL 4000E Multitrack Consoles.
Power requirements 24 V dc at 250 mA max. Approx. 750 mm
high Box 220 x 120 x 100 including controls. Supersedes
the AMlO/18 which was abandoned. Sub-units AM10/20B.
