Headphone Distribution Amp
The 99-1215 Harris Headphone amp, originally
designed for the BMX
digital console, can be
repurposed to not only create a headphone amp
system for the studio, but to also give studio
speaker level control to the studio host position.
The 99-1215 has six outputs (typically for one
host and five guests, but in this application for
one host, four guests and one studio monitor am-
plifier) that connect to Harris 99-1214-x head-
phone panels using CAT-5 cables.
The following illustration shows how to use the
99-1215 headphone system with the NetWave. The
three inputs (Host, Co-Host and Guest) connect
to the NetWave console studio outputs: Host HP,
Monitor and Guest HP. By properly setting the
two rear panel switches (S1 and S2) per the illus-
tration, the headphone amp outputs are assigned
as: Host (#1), studio monitor (#2), and up to four
Guests (outputs #3 to #6).

NOTES:
1. Mount this panel below the countertop, or inside the
studio cabinet rack space holding the power amp, mic
processors, headphone amp, etc. The 42" long host
Monitor Fader wiring plugs into this panel.
2. Make a 1/4" TRS adapter cable (tip is the left channel,
ring is the right channel) to go from the 99-1214-1 jack to
the studio monitor power amp. For most applications, the
unbalanced signals easily drive balanced amp inputs. If in
doubt, use an unbalanced to balanced line adapter.
3. To set the monitor output levels on an amplifier with
trim or level controls: adjust the amp controls to full off. Set
the Monitor fader on the studio panel to 0 (full on). Set the
console Studio Monitor pot to maximum. Assign a signal to
the Studio Monitor output, then adjust the amplifier controls
for the desired loudest level. If the signal into the amp is too
hot, adjust the console Studio Monitor pot down until the
signal is not being overdriven and leave it in this position.
Use the Monitor fader in the studio to adjust the speaker
volume as required. The console logic mutes the monitor
audio whenever any studio microphone is on. The output
dims when the console talks to the studio. Talk is routed to
both the studio speakers and to the host headphones. The
guest headphones do not receive talk.
